We've had a lot of requests lately to discuss how we start up our botanical method aquariums. Now sure, we've covered this topic before over the years; yet, as our practices have evolved, so has our understanding about why we do things the way that we do- and why it works.
Establishing a new botanical method aquarium is an exciting, fun, and interesting time. And the process of creating your aquarium is shockingly easy, decidedly un-stressful, and extremely engaging.
The main ingredients that you need are vision, a bit of knowledge, and... patience.
Bringing your tank from a clean, dry,"static display" to a living, breathing microcosm, filled with life is an amazing process. This, to me is really the most exciting part of keeping botanical method aquariums.
And how do we usually do it? I mean, for many hobbyists, we've been more or less indoctrinated to clean the sand, age water, add wood, arrange plants, and add fishes. And that works, of course. It's the basic "formula" we've used for over a century.
Yet, I'm surprised how we as a hobby have managed to turn what to me is one of the most inspiring, fascinating, and important parts of our aquarium hobby journey into what is more-or-less a "checklist" to be run through- an "obstacle", really- to our ultimate enjoyment of our aquarium.
When you think about it, setting the stage for life in our aquariums is the SINGLE most important thing that we do. If we utilize a different mind set, and deploy a lot more patience for the process, we start to look at it a bit differently.
I mean, sure, you want to rinse sand as clean as possible. You want make sure that you have a piece of wood that's been soaked for a while, and..
Wait, DO you?
I mean, sure, if you don't rinse your sand carefully, you'll get some cloudy water for weeks...no argument there.
And if you don't clean your driftwood carefully, you're liable to have some soil or other "dirt" get into your system, and more tannins being released, which leads to...well, what does it lead to?
I mean, an aquarium is not a "sterile" habitat. Let's not fool ourselves.
The natural aquatic habits which we attempt to emulate, although comprised of many millions of times the volumes of water volume and throughput that we have in our tanks- are typically not "pristine"- right? I mean, soils from the surrounding terrestrial environment carry with them decomposing matter, leaves, etc, all of which impact the chemistry, oxygen-carrying capacity, biological activity, and of course, the visual appearance of the water.
And that's kind of what our whole botanical-method aquarium adventure is all about- utilizing the "imperfect" nature of the materials at our disposal, and fostering and appreciating the natural interactions between the terrestrial and aquatic realms which occur.
Of course, much like Nature, our botanical-method aquariums make use of the "ingredients" found in the abundant materials which comprise the environment. And the "infusion" of these materials into the water, and the resulting biological processes which occur, are what literally make our tanks come alive.
And yeah, it all starts with the nitrogen cycle...
We can embrace the mindset that every leaf, every piece of wood, every bit of substrate in our aquariums is actually a sort of "catalyst" for sparking biodiversity, function, and yes- a new view of aesthetics in our aquariums.
I'm not saying that we should NOT rinse sand, or soak wood before adding it to our tanks. What I AM suggesting is that we don't "lose our shit" if our water gets a little bit turbid or there is a bit of botanical detritus accumulating on the substrate. And guess what? We don't have to start a tank with brand new, right-from-the-bag substrate.
Of course not.
We can utilize some old substrate from another tank (we have done this as a hobby for decades for the purpose of "jump starting" bacterial growth) which also has the side benefit of providing a different aesthetic as well!
And, you can/should take it further: Use that slightly algal-covered piece of driftwood or rock in our brand new tank...This gives a more "broken-in look", and helps foster a habitat more favorable to the growth of the microorganisms, fungi, and other creatures which comprise an important part of our closed aquarium ecosystems.
In fact, in a botanical-method aquarium, facilitating the rapid growth of such biotia is foundational.
It's perfectly okay for your tank to look a bit "worn" right from the start. Functional aesthetics once again! the look results from the function.
In fact, I think most of us actually would prefer that! It's okay to embrace this. From a functional AND aesthetic standpoint. Employ good husbandry, careful observation, and common sense when starting and managing your new aquarium.
So don't obsess over "pristine." Especially in those first hours.
The aquarium still has to clear a few metaphorical "hurdles" in order to be a stable environment for life to thrive.
I am operating on the assumption (gulp) that most of us have a basic understanding of the nitrogen cycle and how it impacts our aquariums. However, maybe we don’t all have that understanding. My ramblings have been labeled as “moronic” by at least one “critic” before, however, so it’s no biggie for me as said “moron” to give a very over-simplified review of the “cycling” process in an aquarium, so let’s touch on that for just a moment!
During the "cycling" process, ammonia levels will build and then suddenly decline as the nitrite-forming bacteria multiply in the system. Because nitrate-forming bacteria don't appear until nitrite is available in sufficient quantities to sustain them, nitrite levels climb dramatically as the ammonia is converted, and keep rising as the constantly-available ammonia is converted to nitrite.
Once the nitrate-forming bacteria multiply in sufficient numbers, nitrite levels decrease dramatically, nitrate levels rise, and the tank is considered “fully cycled.”
And of course, the process of creating and establishing your aquariums ecology doesn't end there.
With a stabilized nitrogen cycle in place, the real "evolution" of the aquarium begins. This process is constant, and the actions of Nature in our aquariums facilitate changes.
And our botanical-method systems change constantly.
They change over time in very noticeable ways, as the leaves and botanicals break down and change shape and form. The water will darken. Often, there may be an almost "patina" or haziness to the water along with the tint- the result of dissolving botanical material and perhaps a "bloom" of microorganisms which consume them.
This is perfectly analogous to what you see in the natural habitats of the fishes that we love so much. As the materials present in the flooded forests, ponds, and streams break down, they alter it biologically, chemically, and even physically.
It's something that we as aquarists have to accept in our tanks, which is not always easy for us, right? Decomposition, detritus, biofilms- all that stuff looks, well- different than what we've been told over the years is "proper" for an aquarium. And, it's as much a perception issue as it is a husbandry one. I mean, we're talking about materials from decomposing botanicals and wood, as opposed to uneaten food, fish waste, and such.
What's really cool about this is that, in our community, we aren't seeing hobbyists freak out over some of the aesthetics previously associated with "dirty!"
It's seen as a fundamental part of the evolution of the tank.
And soon, you'll see the emergence of elegant, yet simple life forms, such as bacterial biofilms and fungal growths. We've long maintained that the appearance of biofilms and fungi on your botanicals and wood are to be celebrated- not feared. They represent a burgeoning emergence of life -albeit in one of its lowest and (to some) most unpleasant-looking forms- and that's a really big deal.
Biofilms, as we've discussed ad nauseam here, form when bacteria adhere to surfaces in some form of watery environment and begin to excrete a slimy, gluelike substance, consisting of sugars and other substances, that can stick to all kinds of materials, such as- well- in our case, botanicals. It starts with a few bacteria, taking advantage of the abundant and comfy surface area that leaves, seed pods, and even driftwood offer.
The "early adapters" put out the "welcome mat" for other bacteria by providing more diverse adhesion sites, such as a matrix of sugars that holds the biofilm together. Since some bacteria species are incapable of attaching to a surface on their own, they often anchor themselves to the matrix or directly to their friends who arrived at the party first.
Tannin's creative Director, Johnny Ciotti, calls this period of time when the biofilms emerge, and your tank starts coming alive "The Bloom"- a most appropriate term, and one that conjures up a beautiful image of Nature unfolding in our aquariums- your miniature aquatic ecosystem blossoming before your very eyes!
The real positive takeaway here:
Biofilms and fungal growths are really a sign that things are working right in your aquarium! A visual indicator that natural processes are at work, helping forge your tank's ecosystem.
About a year ago, had a discussion with our friend, Alex Franqui. His beautiful Igarape-themed aquarium pictured above, "bloomed" beautifully, with the biofilms, fungal growths, and sediments working together to create a stunning, very natural functioning- and appearing-ecosystem. He was not repulsed at all. Rather, he was awed and fascinated...He celebrated what was occurring in his tan. He has an innate understanding of the ecological process, and replaced "fear and loathing" with excitement.
Alex is a hardcore aquascaper, and to see him marveling and rejoicing in the "bloom" of biofilms in his tank is remarkable.
He gets it.
And it turns out that our love of biofilms is truly shared by some people who really appreciate them as food...Shrimp hobbyists! Yup, these people (you know who you are!) go out of their way to cultivate and embrace biofilms and fungi as a food source for their shrimp.
They get it.
And this makes perfect sense, because they are abundant in Nature, particularly in habitats where shrimp naturally occur, which are typically filled with botanical materials, fallen tree trunks, and decomposing leaves...a perfect haunt for biofilm and fungal growth!
Nature celebrates "The Bloom", too.
There is something truly remarkable about natural processes playing out in our own aquariums, as they have done for eons in the wild.
Time for a little thought experiment...
You're a fish.
Seriously. Make yourself a fish...for a second. (I think I'd be a Black Ghost Knife, FYI. What, you thought I'd be a Cardinal Tetra or something? Really? Sheesh!)
Your main goals in life are avoiding predators, finding food, and reproducing. The "finding food" part is what we're focusing on in this experiment.
Now, back to being you for a second.
Would you like to move into a house which didn’t have a refrigerator full of food? I wouldn’t, for sure. Unlike humans, fishes seem to have not lost their "genetic programming" for grazing and hunting for food. Let’s face it—most of the waking hours of aquatic animals are devoted to acquiring food and reproducing. They need to have some food sources available to "hunt and graze" for.
So why not help accommodate our your animals’ needs by supplementing their prepared diet with some “pre-stocked” natural foods in their new home? You know, slow down, get things "going" a bit, and then add the fishes?
I’m not talking about tossing in a few frozen brine shrimp hours before the first fishes go in the tank—I’m talking about a deliberate, systematic attempt to cultivate some living food sources within the system before a fish ever hits the water! Imagine a “new” system offering numerous foraging opportunities for its new inhabitants!
in our world, that might mean allowing some breakdown of the botanicals, or time for wood or other botanicals to recruit some biofilms, fungi- even turf algae on their surfaces before adding the fishes to the aquarium.
“Scott. You’re being impractical here! It could take months to accomplish this. I’ve just spent tons of money and time setting up this tank and you want me to deliberately keep this tank devoid of fishes while the biofilms form and Daphnia reproduce?”
I am a bit crazy. I’ll give you that.
Yet, with my last few systems, this is exactly what I did.
Well, for one thing, it creates a habitat for sighs which is uniquely suited to their needs in a different way.
Think abut the way most fishes live. They spend a large part of their existence foraging for food. Even in the cozy, comfortable confines of the aquarium.
So, why not create conditions for them which help accommodate this instinctive behavior, and provide opportunities for supplemental (or primary!) nutrition to be available to them by foraging.
Now, I have no illusions about this idea of "pre-stocking" being a bit challenging to execute.
I’m no genius, trust me. I don’t have half the skills many of you do but I have succeeded with many delicate “hard-to-feed” fishes over my hobby “career.”
Any "secret" to this?
None at all. I'm simply really fucking patient.
Success in this arena is simply a result of deploying..."radical patience." The practice of just moving really slowly and carefully when adding fishes to new tanks.
A really simple concept.
I mean, to some extent, we already deploy this practice with our botanical-method tanks, right? The very process of creating a botanical-method aquarium lends itself to this "on board supplemental food production" concept. A concept that's pretty analogous to what occurs in Nature, right?
And one of the most important functions of many botanically-influenced wild habitats is the support of food webs. As we've discussed before in this blog, the leaf litter zones in tropical waters are home to a remarkable diversity of life, ranging from microbial to fungal, as well as crustaceans and insects...oh, and fishes, too! These life forms are the basis of complex and dynamic food webs, which are one key to the productivity of these habitats.
You can do this. You can foster such a "food web"- or the basis for one- in your aquarium!
Wait a minimum of three weeks—and even up to a month or two if you can stand it, and you will have a surprisingly large population of micro and macro fauna upon which your fishes can forage between feedings.
Having a “pre-stocked” system helps reduce a considerable amount of stress for new inhabitants, particularly for wild fishes, or fishes that have reputations as “delicate” feeders.
And think about it for a second.
This is really a natural analog of sorts. Fishes that live in inundated forest floors (yeah, the igapo again!) return to these areas to "follow the food" once they flood. In fact, other than the physical flooding itself, this pursuit of food sources is the key factor in the migration of fishes into these habitats.
So, what would some candidate organisms be for "pre-stocking" a botanical-style aquarium?
How about starting with (okay, sounding a bit commercial, I know, but...) the versatile Purple Non Sulphur Bacteria (PNSB), Rhodopseudomonas palustris- the species which forms our product, "Culture." PNSB are useful for their ability to carry out a particularly unusual mode of metabolism: "anaerobic photoheterotrophy."
In this process, they consume organic wastes while inhabiting moderately illuminated and poorly oxygenated microhabitats (patches of detritus, leaf litter beds, shallow depths of substrate, deeper pores of expanded clay media, etc.). In addition to helping to maintain an ecologically stable microhabitat, "Culture" provides a nutritious live food source for zooplankton as well as soil mesofauna.
Yeah, these guys form the "foundation" of your food chain! (And yeah, we'll have "Culture" back in stock soon...we're re-thinking the packaging to make the product more affordable!)
Next, perhaps some "starter cultures" of organisms like Paramecium, Euglena, etc. You know, "infusoria" from the old school aquarium literature. And then, small crustaceans like Daphnia, and copepods of various types.
Pure cultures of all of these organisms are available online from various biological supply houses. They're a fantastic source of biodiversity for your aquarium!
Of course, the more daring among you may want to introduce various worms, like "Black Worms" or Tubifex worms, if you can find clean cultures of them. For that matter, even "blood worms", which are actually the larval phase of the midge.
Some organisms, such as nematodes and chironomids ("Bloodworms!") will dig into the leaf structures and feed on the tissues themselves, as well as the fungi and bacteria found in and among them. These organisms, in turn, become part of the diet for many fishes.
These organisms, in turn, become part of the diet for many fishes.
And the resulting detritus (here we go again!) produced by the "processed" and decomposing plant matter is considered by many aquatic ecologists to be an extremely significant food source for many fishes, especially in areas such as Amazonia and Southeast Asia, where the detritus is considered an essential factor in the food webs of these habitats.
It performs the same function in an aquarium- if we allow it to.
And of course, if you observe the behavior of many of your fishes in the aquarium, such as characins, cyprinids, Loricariids, and others, you'll see that, in between feedings, they'll spend an awful lot of time picking at "stuff" on the bottom of the tank. In a botanical method aquarium, this is a pretty common occurrence, and I believe an important benefit of this type of system.
When you start seeing your fishes "graze" casually on the materials that pop up on your driftwood and botanicals, you start realizing that, although it might not look like the aesthetics we have had in mind in years past, it is a beautiful thing to our fishes!
You can do this.
Remember, it's all part of the game with a botanical-influenced aquarium. Understanding, accepting, and celebrating "The Bloom" is all part of that "mental shift" towards accepting and appreciating a more truly natural-looking, natural-functioning aquarium.
The "price of admission", if you will- along with the tinted water, decomposing leaves, etc., the metaphorical "dues" you pay, which ultimately go hand-in-hand with the envious "ohhs and ahhs" of other hobbyists who admire your completed aquarium when they see it for the first time.
Stay studious. Stay diligent. Stay observant. Stay patient...
And Stay Wet.
through line (N): "A common or consistent element or theme shared by items in a series or by parts of a whole."
I recently returned from another speaking gig.
This time, I was in St. Louis, Missouri, in the midwest of the U.S. I visited a club with some very advanced, super-talented hobbyists, some who are icons in various hobby specialities. It was a lot of fun, as they almost always are. However, this one- THIS trip- left me with some really profound revelations about the hobby which I'm still processing.
An added bonus is that I was able to visit the amazing botanical method aquariums of our friend, Melanie Holmes. It was beyond satisfying to see a truly talented hobbyist find Her way in the hobby, evolving from "traditional" planted aquascaped tanks into the botanical method.
Observing her work, it was easy to see how Her skill from one "genre" translated into our little speciality. The "through line" was a great understanding of the ecology of aquariums. Here tanks were a celebration of life, aesthetic, and ecology. Any one of them was among the best botanical-method aquariums ever created, IMHO.
I was also able to visit a fish room of a very advanced killifish breeder, and it was not only educational for me, it was enlightening...I took particular note of the techniques and approaches that he was utilizing to manage a large number of aquariums, and to keep a "work flow" of fishes going at all times.
Perhaps what was most memorable to me was how he made adjustments to his techniques, like inducing spawning, egg collection, incubation, and production of live foods.
His function-first approaches to light and temperature manipulation, egg collection, incubation approaches, and even how fry were reared- all demonstrated a keen understanding of the needs of his fishes, and an understanding of the environments- and environmental cues- which the fishes needed to trigger spawning events.
Although the process was more "methodical" than "natural", in that it involved sort of "deconstructing" how Nature works in the wild- all of the techniques he employed were simply practical and simple recreations of natural processes to accomplish what Nature does-just in a more "controlled" manner.
Killifish, IMHO, are the ultimate example of how fishes are intimately tied to their habitats. The techniques which modern killie keepers utilize to spawn their fish, incubate the eggs, and rear the resulting fry are a direct distillation of an understanding of this relationship.
Indeed, there was a "through line" of sorts, running from the wild savannah pools and forest streams of East Africa, to the tightly-controlled environment of this suburban St. Louis basement.
It was profound. It was inspiring. It was amazing.
Now, sure, I wasn't seeing fishes being kept in tanks with accumulations of leaf litter over a shallow sedimented substrate, with overhanging terrestrial vegetation. Literal recreations of their natural habitats. Rather, I was seeing the pragmatic application of "biotope replication!" Yeah, it doesn't always have to look like it to function like it!
A huge "unlock" for me, really.
What we've longed called "natural" in the aquairum hobby can take on more than one meaning. I mean, I have consistently railed on the use of the term "natural" when those "high concept", artistically-styled "Nature Aquariums" are proferred to us as "natural" for some very specific reasons; in particular, the fact that they are often touted as "looking just like Nature", an assertion which makes me want to vomit. They generally don't look like wild aquatic habitats.
They're simply beautiful aquariums, skillfully executed.
However, I really can't deny that, on a purely ecological level, they DO function like natural aquatic systems to a certain extent, relying on energy/nutritoinal inputs, and yielding growth of aquatic plants. It's just again, a sort of "deconstructed" approach.
I think that it's the "cultural arrogance" and embrace of the most superficial aspects of aquarium keeping, coupled with the constant assertion that these tanks "look like natural aquatic habitats" by the proponents who surround the "Nature Aquarium" movement, which has always turned me off about them.
Not the work itself.
The reality is that these systems do require the aquarist to reproduce natural processes to some extent in order to be successful. An understanding of the ecology of aquatic plants and their environment is necessary.
Another "through line" from Nature to aquarium...
And of course, there is what we call the "botanical method"- an approach that seeks to more literally recreate the ecology of wild aquatic ecosystems in the aquarium.
To a certain extent, it's the "oldest game in town" in the aquarium world- the approach which lovers of aquatic life centuries before us took to keeping fishes: Toss in some soil, leaves, twigs, and plants and attempt to recreate the wild aquatic habitat as accurately as possible. We incorporate these materials in our tanks because they're what's found in the environments from which our fishes come, right?
Yeah. An homage to Nature by attempting to replicate the function of Nature. And making the effort to understand the relationship between fishes and their habitats.
It's not some arcane idea, is it?
A "through line", for sure!
All we are doing with any aquarium, wether we are conscious of it or not- is attempting to reproduce the functions of natural aquatic ecosystems in our tanks.
The idea of creating a multi-tiered ecosystem, which provides a lot of the requirements needed to operate successfully with just a few basic maintenance practices, the passage of time, a lot of patience, and careful observation- is something that has been discussed, but rarely executed in the modern aquarium hobby until quite recently...
Not because it's difficult to execute.
Not because it's hard to grasp the underlying concepts.
It's because it's difficult to try something which seems so "contrary" to what we are constantly exposed to in social media and elsewhere. It means doing something which we may find uncomfortable, because we're told it's "dangerous" or "reckless" or "dirty" or whatever, by pundits who neither understand nor appreciate what it means to embrace a truly natural, ecological approach to aquarium keeping.
It means adopting a different outlook, accepting a different, yet very beautiful aesthetic. It's about listening to Nature instead of the dude on Instagram with the flashy, artistically-presented, gadget-driven tank. It's not always comfortable at first for some to try, and it initially seems like you're somehow doing things wrong.
Yet, executing this type of tank is about as basic as aquarium-keeping gets.
The difficult part is understanding that this is an extremely natural, ecologically beneficial process, and accepting that it does facilitate the appearance of some things that you might not be comfortable with initially (like, cloudy water, fungal threads, biofilms, decomposition...all that stuff!). Making those mental shifts to accept something different than what the aquarium hobby establishment has proffered as the way to go for generations...
Yet it's not that different than what our distant ancestors did when they set up what we now refer to as an "aquarium."
A through line...one which requires mental shifts and adoption of a long-term mindset.
You have to give things time to establish and settle.
It's about patience.
It's about faith.
Faith in Mother Nature, who's been doing this stuff for eons. Faith that you're doing something which embraces Nature's processes so fully.
The truest, straightest "through line" there is in the aquarium hobby.
Stay diligent. Stay curious. Stay observant. Stay patient. Stay engaged...
And Stay Wet.
Our approach to aquarium keeping is as much a "mindset" as it is a practice. And, although the practical techniques are relatively easy to grasp and execute, the philosophical components can be confusing and seem a bit contradictory at times.
We preach radical patience, yet completely embrace the idea of dramatically changing things within the greater "mindset."
Yeah, you should just do what feels right to you.
And sometimes, that means creating an aquarium which doesn't look anything like you'd want it to until long after it's been established. Other times, it means tearing stuff apart immediately and "re-directing" your tank based on a different vision.
Yet, I always urge you to take a slightly longer view of what''s going on in your tank. Not to rush to completely tear your aquarium apart just because it doesn't seem to be getting to where you want it to go right after you set it up.
Stuff takes time.
Looking back on some of my favorite tanks that I've executed in the past few years, it becomes increasingly obvious to me that these systems really didn't completely hit that "look and feel" that I want until long after they'd evolved naturally...however long that took. It seems that , in the botanical-method aquarium, stuff needs to acquire a "patina" of biofilm, a "stain" from the tannins, and decomposition of botanical materials needs to really begin before one of these systems turns "functional" as well.
That's part of why using aesthetics only as an evaluation criteria for a successful botanical-method aquairum falls a bit short, IMHO.
I mean, every new botanical-method tank likely looks cool to a broader swatch of the aquarium world from day one, if you're just using superficial aesthetics as your metric...But the long-established ones stand out for what they really are. After 4-6 months, that's when things get really special. After Nature has done a lot of the real "work" on the tank.
The decomposition of materials in water impacts our aesthetics greatly, as we all know by now. And that is what's so intriguing. The crisp leaves and dry, lifeless twigs that you submerge will evolve into a dynamic, ever-changing microcosm.
Every tank can get there.
Simply by exercisng patience, and letting your aquarium be.
I've long held that perhaps my fave botanical-method aquarium of all was the one I did about 3 years ago..an aquarium utilizing mangrove wood, extensive leaf litter, and catappa bark throughout. This is probably the only tank in recent years that I've truly regretted changing and moving on from! 😂
I knew what it was I wanted from the tank at the start, but it didn't look like much at first...It would have tested a lot of people's faith if they saw it in it's early stages!
It literally looked like shit for the first couple of months of it's existence: Slightly tinted water, a contrived-looking "campfire-like" wood stack, bare sand, and mostly intact botanical materials. I had to do a bunch of "iterations" with the hardscape to get it where I wanted it. It looked quite "contrived" at points, but I knew instinctively that if I waited it out, let Nature do Her thing- that the potential was huge in this tank.
Sure enough, a few months in, biofilms started forming. The wood acquired that "patina" we talk about so much. Leaves and botanicals broke down...And the water took on perhaps the most earthy-looking, deeply mysterious color I've seen in a botanical-influenced blackwater aquarium.
By some standards, the water in the tank could be described as almost "turbid"- taking on an appearance as though there were fine materials in the water column. Yet, the tank had a real magical appearance with the lighting; the fishes were as colorful, relaxed and happy as any I've ever seen, and the water parameters were spot-on and consistent for as long as the tank was set up.
The essence of "wabi-sabi", for sure. Transience, the ephemeral aspects of our botanicals...the wonders of Nature, embraced.
It just took a little time.
I could have "intervened" at a number of junctures- trying to "circumvent" these aesthetic "deviations" while the tank was evolving. However, I knew not to. I knew that the long-term gains from letting this system evolve would far exceed any "relief" I'd gain from siphoning out the biofilms, removing decomposing leaves, and clearing the water.
And, as usual- Nature delivered...because I didn't get in Her way.
We've done this numerous times with similar results. Inauspicious starts.
Botanical-method aquariums typically require more time to evolve than more "conventional" aquariums do. They are dependent upon the development of a specialized ecology, which includes fostering organisms like fungal growths and biofilms.This process can be "expedited" or manipulated a bit, but to achieve truly meaningful and beneficial results, you just can't rush stuff!
You can't interrupt it, either.
When you do, as we've learned, results can be, well- "different" than they would be if you allow things to continue on at their own pace. Not necessarily always "bad"- just not as good as what's possible if you relax and let Nature run Her course without interruption. Following a plan is never a bad idea; it can lead to some exciting destinations.
However, the ability to "pivot" and "go with the flow" is really important, too.
It's not always a bad idea to switch things around if you're suddenly inspired to do so. What I hate to see is when hobbyists attempt to "intervene" on the processes which are occurring in the tank- like the recruitment of biofilms and fungal growths, the breakdown of leaves, etc. THAT'S a problem, imho. You can change the "overall theme" without irrevocably interrupting Nature's processes.
Yeah, there IS a certain kind of "intervention" which I occasionally embrace myself. As I've previously discussed here, on occasion, I'll start to execute on an idea I've had, and very early (or sometimes, not so early) in the process, I'll completely lose interest in it for whatever reason (it can be anything from "not feeling it!" to "I hate that I can't hide that heater!"), and the desire to abort and move on to something else on my "to do list" beckons.
In general, however, I play a really long game.
One which acknowledges that the fact that our botanical-method aquariums evolve over very long periods fo time, not reaching the state that we perhaps envisioned for many months. My actions reflect this mindset. Unless there is some major emergency, about the only thing that I might do is to add a few more botanicals, re-arrange some wood, or just wait it out.
Of course, if you really are "not feeling it" (it happens!), does it mean tearing the whole thing apart and starting over?
You can change the "look" or aesthetic direction of an aquairum- fairly significantly- without disrupting its function.
One of the things I've done a lot in recent years when making big changes to aquariums is to keep the substrate layers from my existing tanks and "build on them." It makes a ton of sense, really. Why waste this goodness, just because the "theme" of the "new" tank is different than the existing one?
Your South American-themed tank won't be that much different if you change up the "hardscape" to turn it into s Southeast Asian-themed tank, while leaving the substrate layer intact, right?
In other words, I'm taking advantage of the well-established substrate layers, complete with their sediments, decomposing leaves and bits of botanicals, and simply building upon them with some additional substrate and leaves. I've done this many times over the years- and I'm sure a lot of you have, too-it's hardly a "game-changing" practice, but it's something not everyone talks about.
I believe that preserving and building upon an existing substrate layer provides not only some biological stability (ie; the nitrogen cycle), but it has the added benefit of maintaining some of the ecological diversity and richness created by the beneficial fuana and the materials present within the substrate.
I know many 'hobby old timers" might question the safety- or the merits-of this practice, mentioning things like "disturbing the bacterial activity" or "releasing toxic gasses", etc. A lot of 'em would rather have you simply remove this stuff altogether. It's "all or nothing" for them! I'm not sure how leaving the substrate layer intact is problematic. It doesn't "die." I believe that particular belief is steeped in "aquarium mythology", conflates a lot of different ideas and topics, and has generally been misapplied and misunderstood over the years.
I simply have never experienced any issues of this nature from this practice. Well maintained systems generally are robust and capable of evolving from such disturbances. And we're not really "disturbing" the substrate when we preserve it, are we? Moving around a few pieces of wood or rock might cloud the water a bit, but it's not wholesale disturbance of the substrate.
I see way more benefits to this practice than I do any potential issues.
Since I tend to manage the water quality of my aquariums well, if I say so myself, I have never had any issues, such as ammonia or nitrite spikes, by doing this- in fresh or saltwater systems. It's a logical way of maintaining stability and continuity- even in an arguably disruptive and destabilizing time!
This idea of a "perpetual substrate"- keeping the same substrate layer "going" in successive aquarium iterations- is just one of those things I believe that we can do to replicate Nature in an additional way.
Well, think about it for just a second. In Nature, the substrate layer in rivers, streams, and yeah, flooded forests and pools tends to not completely wash away during wet/dry or seasonal cycles.
Oh sure, some of the material comprising the substrate layer may get carried away by currents or other weather dynamics, but for the most part, a good percentage of the material- and the life forms within it- remains when the water recedes. Wind and weather add additional materials to the now terrestrial environment, which become part of the aquatic habitat when the waters return.
So, by preserving the substrate from the previous iteration of your aquarium, and perhaps "refreshing" it a bit with some new materials (ie; sand, sediment, gravel, leaves, and botanicals), you're essentially mimicking some aspects of the way Nature functions in these wild habitats!
And, from an aquarium management perspective, consider the substrate layer a living organism (or "collective" of living organisms, as it were), and you're sure to look at things a bit differently next time you "re-do" a tank!
I suppose, one could view the process of "perpetuating" the substrate almost like persuing "eternal youth"- it's not entirely possible to achieve, but you can easily embrace the idea of renewal and continuity within your aquarium. It's a very natural process. Perhaps it's even beneficial in some way over the long term?
Things change in Nature, some things are utilized elsewhere, and other things are preserved in situ. Nothing goes to waste.
Rather, stuff gets "folded" into the changing ecosystem. Leaves on the forest floor become a lush ecological niche for fungal growth and bacteria, and a grazing substrate for fishes when submerged. Tree branches become "attachment points" for epiphytic plants, sponges, and other aquatic life forms.
Nature is very efficient. We should take a cue from Her! "Disruption" is often a form of renewal and evolution in Nature.
Patience, as always, is the key ingredient here. Of course, this is a hobby, and it should be fun...and you should feel free to change stuff up if it's not. However, make it a point to consider your actions in the "big picture", and it takes on a greater significance.
You need to have an understanding that you're creating a dynamic environment, not simply an "aquascape." And it's constantly evolving- even when you're not ripping it apart! It's anything but "static"-sort of like a planted aquarium, but in reverse (rather than plants growing, the botanicals are, for want of a better word "diminishing")! At any given time, you'll have materials like leaves in various states of decomposition, seed pods, slowly softening, breaking down, and recruiting biofilms and a "patina" of fungal growth.
It begs the most fundamental of questions about our botanical method practice:
What happens over time in a botanical method aquarium? What changes occur along the way?
Well, typically, at its simplest, as most of you who've played with this stuff know, the botanicals will begin to soften and break down. Botanical materials are the very definition of the word "ephemeral." Nothing lasts forever, and botanicals are no exception! Pretty much everything we utilize- from Guava leaves to oak twigs- starts to soften and break down over time.
Most of these materials should be viewed as"consumables"- meaning that you'll need to replace them over time if you want maintain some environmental consistency. Again, perfectly analogous to what occurs in Nature.
You're not an "aquascaper" in the classic hobby sense when you play with these types of systems. Rather, you're a a sort of "superintendent" to Nature, helping Her do what she has done for eons. You're not simply an idle "passenger," either- you play an active role in conceiving, setting up, and maintaining such a system. You need to take some cues from Nature, and that often means simply standing by and observing as she does Her work and goes through Her process.
You learn. You evolve with your aquarium, on a very real level.
Sometimes, it requires intervention on your part- at least in your own mind, perhaps. Other times, it simply involves sitting back, letting things unfold, and observing patiently.
Watching a display aquarium evolve and sort of "find itself" naturally over time is proving to be one of the most enjoyable discoveries I've made in the hobby in decades. It's a mindset that I actually had in my youth- by necessity, because I had very limited resources except for time- yet lost as I grew into adulthood and "evolved" in the hobby. With more skills and economic resources, I could "do more"- but the reality is that it wasn't always the right thing.
It took me a few decades after hitting so-called "advanced" hobbyist status before it really hit me that, by simply studying the function of natural ecosystems, all of the answers I needed to be successful as an aquarist were right there! I just needed to figure out which questions to ask.
I'm still deep in that process, decades later!
By understanding that my aquariums are governed by the same "laws" which apply to natural aquatic ecosystems, and developing and following simple practices and husbandry routines to embrace this, and monitoring what's occurring in the tank (as opposed to constantly trying to intervene to "pre-empt" what we in the hobby have commonly perceived to be problems), I've personally had more beautiful, healthy and stable aquariums, and...more success than ever before.
Accepting that there is most definitely an elegant, yet complex ecological "dance" in our aquariums, and becoming an "active monitor" instead of an "active intervener" has added an enjoyable and rewarding aspect to my love of the hobby.
I think that this approach to the "dance" not only makes you a more engaged hobbyist, it gives you a remarkable appreciation for the long term evolution of an aquarium; an appreciation for the pace by which Nature operates, and the direction in which your aquarium ultimately goes.
By doing this, you get the enjoyment of seeing the "evolution" every day! Observing and enjoying the subtle nuances of your aquarium at every stage of its existence. With my "go slow" mindset and practice, the differences are subtle in the short term- the "payoffs" really more apparent over the longer term.
Again, it's okay to make changes- even significant ones- to the "theme" of your aquarium. However, it's simply not good practice to interfere with the processes which allow it to become what Nature ( and YOU, too, if you're honest with yourself) wants it to become.
I know, it does feel a bit "yin" and "yang"- like I'm pulling from both sides- telling you, on one hand, that it's okay to make significant changes to a tank, while simultaneously urging you to deploy extreme patience and an almost "sit back and relax" approach...These seemingly diametrically opposite actions actually work really well together when you have the "common denominator" of good intentions, vision, careful actions, and an appreciation for what Nature can do if we let Her.
This philosophy, like so many things I ask you to consider here- doesn't always seem to make any sense.
Until it does.
Be kind to yourself- and to Nature.
Trust that She'll guide your aquarium effectively along the way to its ultimate potential. She won't let you down. Even if you take a slight detour now and again.
Stay confident. Stay observant. Stay curious. Stay patient....
And Stay Wet.
You saw the title.
What exactly am I talking about here?
Today, I want to double back and talk a bit about our gooey friends, the fungi- for just a few minutes. Despite their off-putting appearance to some, they may be among the most beautiful, elegant, and useful organisms we encounter in the aquatic world.
Why do I have such devotion to organisms which most of us find truly revolting in appearance?
Because they are among the most important and useful organisms which we can have in our botanical method aquariums. Think about how they arrive in aquatic ecosystems, what they consume, how they derive nutrition, and what they do for the overall ecosystem.
As everyone knows, when you put stuff in water, one of four things seems to happen:
2) It gets covered in a gooey slime of fungal growth, and "biofilm."
3) It starts to break down and decompose.
4) Both 2 and 3
Now, it's pretty much a "given" that any botanicals or leaves that you drop into your aquarium will, over time, break down. Wood, too. And typically, before they break down, they'll "recruit" (a fancy word for "acquire') a coating of some rather unsightly-looking growth. Well, "unsightly" to those who have not been initiated into our little world of decomposition, fungal growth, biofilms, tinted water, etc., and maintain that an aquarium by definition is a pristine-looking place without a speck of anything deemed "aesthetically unattractive" by the masses!
So, with that little explanatory passage out of the way, let's take a closer look at fungi-the stuff that you'll see covering the leaves, botanicals, and wood that you place into your aquarium, and why you actually WANT the stuff there in the first place.
The fungi known as aquatic hyphomycetes produce enzymes which break down botanical materials in water. Essentially, they are primary influencers of leaf maceration. They're remarkably efficient at what they do, too. In as little as 3 weeks, as much as 15% of the decomposing leaf biomass in many aquatic habitats is "processed" by fungi, according to one study I found!
Aquatic hyphomycetes play a key role in the decomposition of plant litter of terrestrial origin- an ecological process in rain forest streams that allows for the transfer of energy and nutrients to higher tropic levels.
This is what ecologists call "nutrient cycling", folks.
These fungi colonize leaf litter and twigs and such soon after they're immersed in water. The fungi mineralize organic carbon and nutrients and convert coarse particulate matter into fine particulate organic matter. They also increase leaf litter palatability to shredders, which helps facilitate physical fragmentation.
Fungi tend to colonize wood and botanical materials, because they offer them a lot of surface area to thrive and live out their life cycle. And cellulose, hemicellulose, and lignin- the major components of wood and botanical materials- are degraded by fungi, which posses enzymes that can digest and assimilate these materials and their associated organics!
Fungi are regarded by biologists to be the dominant organisms associated with decaying leaves in streams, so this gives you some idea as to why we see them in our aquariums, right?
In aquarium work, we see fungal colonization on wood and leaves all the time. Most hobbyists will look on in sheer horror if they saw the same extensive amount of fungal growth on their carefully selected, artistically arranged wood pieces as they would in virtually any aquatic habitat in Nature!
Yet, it's one of the most common, elegant, and beneficial processes that occurs in natural aquatic habitats!
Of course, fungal colonization of wood and botanicals is but one stage of a long process, which occurs in Nature and our aquariums. And, as hobbyists, once we see those first signs of this stuff, the majority of us tend to reach for the algae scraper or brush and remove as much of it as possible- immediately! And sure, this might provide some "aesthetic relief" for some period of time- but it comes right back...because these materials will provide a continuous source of food and colonization sites for fungal growths for some time!
I know that the idea of "circumventing" this stuff is appealing to many, but the reality is that you're actually interrupting an essential, ecologically beneficial natural process. And, as we know, Nature abhors a vacuum, and new growths will return to fill the void, thus prolonging the process.
Again, think about the role of aquatic hyphomycetes in Nature.
Fungal colonization facilitates the access to the energy trapped in deciduous leaves and other botanical materials found in tropical streams for a variety of other organisms to utilize.
As we know by now, fungi play a huge role in the decomposition of leaves, both in the wild and in the aquarium. By utilizing special enzymes, aquatic fungi can degrade most of the molecular components in leaves, such as cellulose,, hemicelluloses, starch, pectin and even lignin.
Fungi, although not the most attractive-looking organisms, are incredibly useful...and they "play well" with a surprisingly large number of aquatic life forms to create substantial food webs, both in the wild and in our aquariums!
Natural habitats are absolutely filled with this stuff...It's like the whole game here- an explosion of life-giving materials, free for the taking...
Yet, we freak the fuck out about it when it shows up.
Another "mental shift", I suppose...one which many of you have already made, no doubt. I certainly look forward to seeing many examples of us utilizing "what we've got" to the advantage of our fishes! AGAIN: A truly "Natural" aquarium is not sterile. It encourages the accumulation of organic materials and other nutrients- not in excess, of course.
The love of pristine, sterile-looking tanks is one of the biggest obstacles we need to overcome to really advance in the aquarium hobby, IMHO.
Biofilms, fungi, algae...detritus...all have their place in the aquarium. Not as an excuse for lousy or lazy husbandry- but as supplemental food sources to "power" the ecology in our tanks.
And of course, as we've discussed many times here, fungi are actually an important food item for other life forms in the aquatic environments tha we love so much! In one study I stumbled across, gut content of over 100 different aquatic insects collected from submerged wood and leaves showed that fungi comprised part of the diet of more than 60% of them, and, in turn, aquatic fungi were found in gut content analysis of many species of fishes!
One consideration: Bacteria and fungi that decompose decaying plant material in turn consume dissolved oxygen for respiration during the process.
This is one reason why we have told you for years that adding a huge amount of botanical material at one time to an established, stable aquarium is a recipe for disaster. There is simply not enough fungal growth or bacteria to handle it. They reproduce extremely rapidly, consuming significant oxygen in the process.
Bad news for the impatient.
Support. Co-dependency. Symbiosis. Whatever you want to call it- the presence of fungi in aquatic ecosystems is extremely important to other organisms.
You can call it free biological filtration for your aquarium!
GREAT news for the patient, the studious, and the accepting.
Think about this: These life forms arrive on the scene in Nature, and in our tanks, to colonize appropriate materials, to process organics both in situ on the things that they're residing upon (leaves, twigs, branches, seed pods, wood, etc.).
Yeah, if you intervene by removing stuf-f bad things can happen. Like, worse things than just a bunch of gooey-looking fungal and biofilm threads on your wood. Your aquarium suddenly loses its capability of processing the leaves and associated organics, and- who's there to take over?
Okay, I'm repeating myself here- but there is so much unfounded fear and loathing over aquatic fungi that someone has to defend their merits, right? Might as well be me!
My advice; my plea to you regarding fungal growth in your aquarium? Just leave it alone. It will eventually peak, and ultimately diminish over time as the materials/nutrients which it uses for growth become used up. It's not an endless "outbreak" of unsightly (to some) fungal growth all over your botanicals and leaves. It goes away significantly over time.
That's "Fellman Speak" for "Please be more fucking patient!"
Seriously, though, hobbyists tend to overly freak out about this kind of stuff. Of course, as new materials are added, they will be colonized by fungi, as Nature deems appropriate, to "work" them.
It's one of those things in the botanical-method aquarium that we need to wrap our heads around. We need to understand, lose our fears, and think about the many positives these organisms provide for our tanks. These small, seemingly "annoying" life forms are actually the most beautiful, elegant, beneficial friends that we can have in the aquarium. When they arrive on the scene in our tanks, we should celebrate their appearance.
Because their appearance is yet another example of the wonders of Nature playing out in our aquariums, without us having to do anything of consequence to facilitate their presence, other than setting up a tank embracing the botanical method in the first place. We get to watch the processes of colonization and decomposition occur in the comfort of our own home. The SAME stuff you'll see in any wild aquatic habitat worldwide.
For those of you who MUST find some familiar comfort in established philosophy- look no further than the beloved master, Takashi Amano. He laid down this track decades ago...
Yup. I'm channeling Mr. Amano here.
In the botanical method aquairum, Amano's concept of embracing the Japanese philosophy of wabi-sabi takes over. Accepting the transient nature of things and enjoying the beauty of the changes that occur over time.
Part of the game, as we've discussed ad naseum here, is to understand, appreciate, and ultimately embrace the way the aquatic environment is influenced by the fungal growths, biofilms, and decomposition which occurs when botanicals are added into our aquariums.
Remember, your aquairum is not a pice of kinetic art. It's a miniature, closed aquatic ecosystem. Processes which occur in Nature play out daily in your tank.
Yeah, I admit, decades ago, I freaked out about seeing fungal growths in my tanks, too. I'd get a bit scared, wondering if something was wrong, and why no one else's aquariums ever seemed to look like mine. I used to think something was really wrong!
To reassure myself, I would stare for hours at underwater photos taken in the Amazon region, showing decaying leaves, biofilms,and fungi all over the leaf litter. I'd read the studies by researchers like Henderson and Walker, detailing the dynamics of wild leaf litter zones and how productive and unique they were.
I remember telling myself that what I was seeing in my tanks was remarkably similar to what I saw in images and videos of wild aquatic habitats that I wanted to replicate. They seem to look- and even function- so similarly.
I'd pour over my water quality tests, confirming for myself that everything was okay. It always was. And of course I would watch my fishes for any signs of distress...
I never saw them.
Truth be known, I knew that there wouldn't be any issues, because I created my aquariums with a solid embrace of basic aquatic biology; an understanding that an aquarium is not some sort of underwater art installation, but rather, a living, breathing microcosm of organisms which work together to create a biome..and that the appearance of the aquarium only tells a small part of the story.
And another big concept for you to wrap your head around:
Your aquarium- or more specificlally- the colonized botanical materials which comprise the botanical-method aquarium "infrastructure" acts as a biological "filter system."
In other words, the botanical materials present in our systems provide enormous surface area upon which beneficial bacterial biofilms and fungal growths can colonize. These life forms, like fungi, utilize the organic compounds present in the water as a nutritional source, thus creating a "nutrient assimilation process."
Understanding and embracing this has changed everything about how I look at aquarium management and the creation of functional closed aquatic ecosystems.
It's really put the word "natural" back into the aquarium keeping parlance for me. The idea of creating a multi-tiered ecosystem, which provides a lot of the requirements needed to operate successfully with just a few basic maintenance practices, the passage of time, a lot of patience, and careful observation.
It means adopting a different outlook, accepting a different, yet very beautiful aesthetic. It's about listening to Nature instead of the "influencer" on YouTube with the flashy, gadget-driven tank and nothing substantive to back up his vapid narrative. It means educating yourself a bit. It's not always fun at first for some, and it initially seems like you're somehow doing things wrong.
But you're not. And Mother Nature won't let you down if you don't lose faith in Her.
And yeah- it's about faith. Faith in Mother Nature, who's been doing this stuff for eons. She's got this. She'll hook you up...If you allow Her. If you have faith in Her processes.
Stay bold. Stay thoughtful. Stay curious. Stay patient...
And Stay Wet.
Welcome to my mind...
Today's little tale is something which many of you may relate to. Perhaps some of you can't relate to it. Others might simply gain value by remaining comfortably at a distance and watching how this unfolds.
It's all good.
I'm now in the final weeks before setting up some new tanks in my home office in my newly remodeled home for the first time in 18 MONTHS! I'm brimming over with new and old ideas, and at least two or three tanks will be going up in a fairly short period of time...
(Yeah, I'm charging my MacBook from the power strip inside that stand...I mean, I'm not running the tank yet, so why waste the outlet? 😆)
It's really exciting for me.
In fact, it's probably the most excited I've been in the hobby in years. Doing without my usual tanks has been agonizing. Like with many of you, aquariums are a huge part of my life and my sanity! I'm stoked to be getting underway again!
Among other things, the intention is to create a new variation of my brackish water mangrove habitat... A long awaited, smaller, shallow version of the highly successful botanical-style brackish tank I created a few years ago.
And of course, whenever there is salt in the equation, my mind begins to wander...
Even though I'm set up to do a full-blown, high-end coral tank early next year, for some reason I simply can't hold back against the idea of just "going all the way" and creating a mangrove-centric marine tank instead of brackish...
I mean, I've been steadily nudging up the specific gravity to 1.010 in my temporary mangrove tank from 1.005.. It IS getting closer all the time to 1.025...full strength marine water...And I never did a "mangrove-first" saltwater tank before...It's something I've been craving to do for years, rather than having them sort of hanging in the background as "supporting players" to the corals...
Of course, the idea was that this time, I'd make them the stars, with perhaps a few sand-dwelling corals like Goniopora, or maybe Catalaphyllia or Cynarina. Or-maybe a small Sarcophyon or some other soft corals... Fishes would likely be some Pajama Cardinal Fish and/or captive-bred Mandarin Dragonets or something small, like gobies...And some seagrasses! Not just a "reef tank with a mangrove in it", which has been done- or at least, contemplated by pretty much every reefer who's ever lived, lol.
Nope, this is a true mangrove-focused marine aquarium.
It's too tempting to not do this. Right?
So, it would be an incredibly biologically rich, diverse, nitrate-loving saltwater tank...a bit different than the way I'll do my coral focused tank, so there is some fun freedom here!
I've got a great little all-in-one tank to play with- an Innovative Marine "Fusion Lagoon 25", with integrated overflow, a wide foot print, and a DC pump ready to go. And I can swap out my Kessil A80 "Tuna Sun" for that cool Kessil A80 "Tuna Blue" with a spectral controller that has just been staring at me from the box for over a year...Yeah, gear... That thing that reefers love...playing with cool gear...I mean, just having a simple, coral-growth-capable little light for this idea is motivation enough for the hardcore reefer in me.
Can't...resist... I just can't stay away...Must execute...
Or, can I?
I mean, I should do another brackish tank.Yeah, I should, right? Or, maybe not... I dunno...
It would be so easy to ease back into my saltwater roots a bit with a significantly different approach to saltwater than I've done in a decade. Bring the whole Tannin philosophy in. Hell, I've been imagining doing a muddy, mangrove and coral estuary-type tank for years, but my coral-focused mindset wouldn't allow it. I never took the time to execute on this idea, being so busy with them as co-owner of a successful coral propagation/import business.
But, that was then.
And now, with this empty tank, what seems like the right situation, and the idea bubbling up once again, it's becoming irresistible. Time to "scratch the itch", right? And yeah, my reefing friends are teasing me a bit with that "peer pressure" sort of thing to do it that only friends can do.
So the idea I had is ridiculously simple:
A deep substrate of NatureBase "Mangal", perhaps topped or mixed with some fine aragonite sand...Modest water flow, perhaps not even supplementing the return flow from the system pump. Modest LED lighting in the 10,000K range for the corals. The aquarium is situated in a locale which receives more than enough ambient natural light to grow the mangroves...in fact, all they've received for almost 3 years is natural room-filtered sunlight and they have grown from small propagules to beautiful seedlings!
I think the biggest challenge in this tank would be restraint...because it's small (only 25 US gallons- squarely in the "nano" category for a "reef" tank), I simply can't keep a whole bunch of coral and fishes in it. And the bioload in a modest sized tank would reflect that. The ecological diversity, however, is where I'm focusing with this one.
Coral-wise, I think I'd be focusing on one two that I really love- Goniopora or Catalaphyllia.
Wow, the familiar alluring glow of "Windex blue" LED light and that "reef smell" are seared into my psyche - it would be so nice to experience them again, right?
Ahh, then there is the thing that gets me. Stops the whole fantasy in it's tracks. Brings me back from my warm, ignorant bliss into the cold light of reality.
I mean, a small aquarium with relatively aggressive corals like the two mentioned above is basically a self-limiting system. OR should I say, it requires the hobbyist to "cool his or her jets", as the expression goes. Unless I want to go "monospecific", the tank runs the risk of turning into a chemical warfare zone, with the super-aggressive Catalaphyllia or Goniopora essentially chemically beating the living shit out of anything else I'd put in there into submission.
That means, little in the way of coral diversity if I want to be responsible. And I do, of course. And really, when you take into account the displacement for substrate, this "25 gallons" really becomes like, I dunno- maybe 18-19 gallons. Squarely in the "nano"marine tank zone- the idea of which has always turned me off. Why?
Not because they're bad. They're not.
It's because I'd be too limited to execute the plan the way I want to. The way it should be executed in an aquarium.
And dealing with a heavy set of ecological factors in a tiny, well-illuminated, not fully-equipped "reef" tank is a recipe for algal blooms and all of the stuff which takes away from the fun of having a unique system, in my mind. I mean, sure, I can handle that stuff- I have many times. Yet, what I can't handle is being soooo limited and size-restricted. Going in knowingly limited in both scope and equipment is a bad handicap for an enjoyable reef experience, IMHO. Yeah, it's against my mindset with reefs to go this route. I suppose that it can be argued that it shouldn't be- tons of successful hobbyists run gorgeous "nano reefs" and derive great pleasure from them.
But they're not me. I'm not them. And I don't feel like outfitting the crap out of a 25-gallon tank to get the system the way I want it.
Ahh, a "champagne problem" for this little aquarium brat, huh? 😂
There is a lesson here:
The enormous power and value which self-awareness brings to us as hobbyists.
I simply couldn't enjoy this tank in that format because it goes against everything that I've previously believed in. I couldn't take this "vanity detour" simply because I didn't want to wait until Spring, as I've planned, to "get my reefing on."
I mean, that's totally against my "patience first" philosophy, isn't' it?
Yeah, seriously. Just super-lame, IMHO. Lowkey STUPID. A surefire recipe for not having fun. And a deviation from patience. Hell, I waited a year and half to have "real" tanks again- what's another few months to have the "crown jewel" of my home aquarium collection properly in place?
I'm going to have my full-blown coral tank soon enough.
And the "Mangrove-centric" marine tank? Maybe some other time. It'd still a really good idea. Every one of my reefing friends wanted me to do it. And me, Scott Fellman- the "Once and Future Reefer"- 7-time MACNA speaker, coral vendor, reef world "A-lister"... What do I want? That's what really matters. And all of that other nonsense..Will I ever get back to that?
Well, at least, the practicing "reefer" part. Who the fuck cares about the "celebrity" bit? It was fun, but never the motivation. "Check the ego part, Fellman."
Just being a "practicing reefer" is a lot of fun...
But this isn't the time for it. I have a different journey to take. Back to the mangal for me.
The brackish execution is something that is super important to me...and, according to feedback I've received from our community- to many of YOU as well. More hobbyists want to learn about this. Brackish is one of those hobby segments that has simply not gotten the attention it has deserved for many years, and to NOT proceed with my "V2.0" brackish tank would be doing the hobby a bit of a...disservice. Yeah, I need to show others how cool and fun this niche segment of the hobby can be when executed a bit differently.
That's how I think!
I mean, it sounds a bit arrogant, I suppose- but the reality is that most brackish tanks I've seen for decades are, well- shitty. And boring. And as you know- we don't do "shitty and boring" around here.
(Not that I haven't ever done "shitty and boring", mind you- but I have no intentions of ever doing that again- if I can avoid it!).
Tannin was founded on the very idea of doing stuff a bit differently than it has been in the past. About pushing boundaries, poking the metaphorical beehive, and just generally approaching things in unique ways. To not do this is a violation of my own ethos, and the founding principles of our company!
Our mission statement in our business plan is, literally, "Do cool shit."
I'm totally serious.
And we WILL do cool shit.
And what about the "mental detour" I took- multiple days of scheming, researching, even talking to my fellow reef geeks...? It was a good exercise. A great exercise, really. One which pushed me to do that "imagineering" as Disney used to call it- to think about ways to execute ideas that formerly were just..ideas. It wasn't a waste of time at all.
I enjoyed all of it.
And I came really, really close to doing it...
I mean, sure, I know that I could have pulled it off.
But in the end, it wasn't right.
It would be abandoning my ideals and principles while engaging in what at best would be a journey into an area that wouldn't have really fulfilled me. Now, there is a lot to be said about the occasional "mental detour"...I mean, always indulge yourself, scheme, think through, research, talk about it with friends...But in the end, you HAVE to listen to yourself; to do what makes your heart really sing.
To do anything less is to deny yourself- and maybe even others- the beauty, joy, and inspiration that can only come when intention, ideas, philosophy, and execution synch up.
Sure, sometimes you actually will have to take the detour. You may and up loving it and creating something brilliant. Or you may be disheartened by it. You never know until you push right to the edge- or further sometimes. Ask anyone who's been there before.
Yet, in this instance, for the reasons we just talked about, and many more that I haven't even begun to articulate here, I'm staying "on plan." I know that this is where I really want to go with this tank at this time. I know that's where I need- and want- to be.
I hope that this little journey into my personal mindset has touched you somehow. I hope that it brought you value. Maybe, perhaps- it gave you the courage to move forward on that little detour, Or, perhaps it made you rethink- and yanked you back from the ledge. Perhaps it simply made you laugh and be thankful that you're not me! 😆
Regardless of how this little discussion touched you today- I hope that it taught you the value of listening to yourself in the hobby. Always.
Yeah, it's time for the cliched Steve Jobs quote- 'cause it's damn applicable in this instance, isn't it?
"Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice."
So, yeah. Stay on task. Stay brave. Stay thoughtful. Stay diligent. Stay creative. Stay patient...
And Stay Wet.
One of the things that we find ourselves doing in the aquarium hobby is using " a little of this and that" in our tanks, because-well- because we seem to be fixated on lots of variety of "stuff" in our tanks, right?
I mean, there is nothing wrong with using a diversity of materials in our aquariums to express our creativity, and I DO own a company which sells a significant variety of natural aquascaping materials...However, I think it's important to consider exactly what it is we're trying to accomplish in our tanks when we select and employ botanical materials in our aquariums.
As we've discussed a lot around here, the idea of using natural materials, like wood, leaves, seed pods, and roots is a faithful representation of many of the wild habitats we obsess over. And more important, it's a functional methodology of fostering natural processes and a healthy ecology in our tanks.
Are you simply trying to add some aquascaping interest to your tank? Are you interested in manipulating the aquarium water chemistry? Perhaps you're attempting to replicate a very specific ecological niche? Setting up a system for breeding fishes or rearing their fry?
There are many, many applications for botanicals in aquariums. A wide range of things you can do with them, and an even wider range of botanicals to do the job. And the most important "job" for botanicals in our aquariums, IMHO, is to foster the ecology of the aquarium...The so-called "microbiome."
And the important thing to know in this context is that you don't have to use 25 different botanicals and leaves in your aquarium to achieve this ecology within your tank. The reality is that, organisms like fungal growth, bacteria, Paramecium, and other microfauna are typically not tied to a specific leaf or seed pod, so not having a huge variety doesn't mean that you won't be able to achieve a significant microbiome within your tank.
So from a "biodiversity" or ecological standpoint, there is no reason why you would need a huge variety of botanicals in a given aquarium. It really boils down to aesthetics. Or, if you're trying to be more "biotopically accurate"- it depends upon the variety of materials that you'd expect to find in the habitat you're interested in replicating.
For example, a flooded forest might have a lot more ( in both density and variety) leaves and seed pods than say, a fast-flowing river, stream, or a small oxbow lake might have. Other locales might simply have a lot of a few materials, like branches and leaves, but minimal amounts of seed pods and other materials.
Maybe you're not trying to replicate any specific habitat at all. Perhaps it's simply a creative expression with botanicals. That's fine. You can use as many or as little as you want...and you still get the "functional" aspects if you don't "edit" them!
How your botanical-style aquarium looks and (to a lesser extent, functions) is dependent upon these types of characteristics. Yet, it's really a matter of what works best for the aquarium that you are trying to create. The power of restraint is a very important factor when playing with botanicals!
Now again, with all of the cool botanical materials available to hobbyists here and elsewhere, it's certainly fun to use a large variety of different materials in your tank! I personally have always been of the opinion that too much variety in a given tank is sort of distracting and just somehow doesn't always look good. I mean, it certainly can..it just doesn't always! Somehow, using a little less variety in a given tank seems to just look a bit better, IMHO.
However, as we've mentioned already, if you're replicating a specific habitat that might have a wide variety of materials in a given small locale, it makes sense, right?
And there is the benefit of a field of botanicals not only cultivating microbial and fungal food sources for fishes, there is the direct consumption of the botanicals (or their constituent materials) by fishes.
Yes, direct consumption of botanicals by fishes is something that we haven't talked all that much about over the years here.
It's long been known that many species of fishes, particularly Panaque/Panaqolus and some Hypostomus/Cochliodon love botanical stuff. These species are equipped with teeth specifically "designed" to gouge wood. And there's probably another odd one or two that consume it as well. Now, you should be aware that wood "eaters" don't consume the wood per se, they consume it as a "by-product" of their overall feeding strategy.
(The "business end" of Panaque nigrolineatus by Neale Monks, used under CC BY-SA 3.0)
In fact, some recent scientific studies have corroborated digestive enzyme activity profiles and gastrointestinal fermentation levels in the fishes’ GI tracts, suggesting that the "wood-eating catfishes" are not true xylivores, such as beavers and termites, but rather, are detritivores like so many other fishes from the family Loricariidae.
In fact, the conclusion of one study indicated that "..the fishes’ whole digestive strategy ranging from intake, to passage rate, digestive enzyme activities, gastrointestinal fermentation, and decreasing surface area in the distal intestine suggests that these fishes are geared for the digestion and assimilation of soluble components of their detrital diet.
However, the wood-eating catfishes do take macroscopic detritus (i.e., woody debris) and reduce it to <1 mm in diameter, which likely has significant consequences for carbon cycling in their environment. Given that much of the Amazonian basin is unstudied, and much of it is under threat of deforestation (leading to more wood in waterways), the wood-eating catfishes may play a crucial role in the dynamics of the Amazonian ecosystem, and certainly in the reduction of coarse woody debris."
(German DP. Inside the guts of wood-eating catfishes: can they digest wood? Journal of Comparative Physiology B, Biochemical, Systemic, and Environmental Physiology. 2009;179(8):1011-1023. doi:10.1007/s00360-009-0381-1.)
And it has some implication for how we keep these fishes in our botanical-style aquariums, right? I mean, we have no shortage of pics of your Plecos tearing into various botanicals, ranging from leaves to seed pods, like the Calotropis pods, Cariniana pods, etc. So, based on the study above, it would suggest that at least part of the pods do form a part of the diet of these fishes, and in the process of consuming them, the fishes are helping enrich the aquarium habitat.
Now, the botanicals themselves may not be "the whole meal" for many fishes, but the biofilms, algal threads, and other biocover which grow on them do provide foraging for many fishes. A number of us have noticed a wide-ranging variety of fishes, from Barbs to characin to cichlids, feeding actively on the materials on the materials which are "recruited" by submerged botanicals.
This type of activity has led me to postulate that the use of botanicals can perform a definite "feeding support function" for a wide variety of fishes. So, I suppose, one advantage of a variety of botanical materials in one tank is that it increases your chances of having something palatable to someone in the tank!
If you've followed us for any length of time, you're well aware that we are not just pushing you to play with natural, botanical-style aquariums only for the pretty aesthetics. I mean, yeah, they look awesome, but there is so much more to it than that. We are almost as obsessed with the function of these aquariums and the wild habitats which they attempt to represent!
Understanding why you're choosing to throw botanicals in your aquarium is as important as it is to understand how to employ them. Regardless of how you employ the botanicals, I cannot stress enough the need to go SLOWLY. There is no need to rush and dump everything in at one time, or in huge quantities. Particularly in an established aquarium, where your animals are used to a certain stable range of parameters...It goes without saying that if your introducing materials which can influence water chemistry and quality, you will need to go slow and exercise common sense.
And, since botanicals are actively "breaking down" in your aquarium over their "service lifetimes", it's important to employ good husbandry techniques (i.e.; monitoring of water quality, water changes, regular filter media changes, etc.). Just remind yourself that aquatic botanicals create a "dynamic" environment, and you'll enjoy using them that much more!
Apart from, "What pods should I use for a _____________ style setup?" the most common question we receive is ""Do I leave them in or let them break down in my tank?"
And of course, our simple, likely unsatisfying answer is..."It's your call!"
It's as much about your aesthetic preferences as it is long-term ecological stability of the aquarium. It's a decision that each of us makes based on our tastes, management "style", and how much of a "mental shift" we've made o except the transient nature of a botanical-style aquarium and its function. There really is no "right" or "wrong" answer here. It's all about how much you enjoy what happens naturally versus what you choose to control in your tank.
I tend to favor Nature. Every time. It's not even close.
But that's just me.
And of course, we can't ever lose sight of the fact that we're creating and adding to a closed aquatic ecosystem, and that our actions in how we manage our tanks must map to our ambitions, tastes, and the "regulations" that Nature imposes upon us.
Yes, anything that you add into your aquarium that begins to break down is bioload.
Everything that imparts proteins, lignins, tannins, organics, etc. into the water is something that you need to consider. However, it's always been my personal experience and opinion that, in an otherwise well-maintained aquarium, with regular attention to husbandry, stocking, and maintenance, the"burden" of botanicals on your water quality is surprisingly insignificant.
Even in test systems which I intentionally "neglected" by conducting very sporadic water exchanges, once I hit my preferred "population" of botanicals (by building them up gradually), I have never noticed significant phosphate or nitrate increases that could be attributed to their presence.
So, once and for all- is adding a bunch of botanicals to your aquarium "dangerous?"
I mean, it could be, in some instances. Like, adding large quantities of fresh botanicals to an established, stable tank all at once is a recipe for problems. But, this is "Aquarium Keeping 101", right? Like, what would you expect that would happen? Why would you even do that?
It's about common sense.
The reality is, adding botanicals to your tank and using them, replacing them regularly, etc, is no more "dangerous" than anything else we do as aquarists. You simply need to go slowly, apply common sense, follow our prep instructions, and observe your tank carefully.
Look, stuff can still occasionally go wrong, even when you follow instructions and employ common sense. Never lose sight of the fact that aquariums are closed natural ecosystems, and changing the delicate ecological balance within them always risks disrupting established biological processes- and that can have consequences for your fishes.
But, you already KNOW that
It's the reality of Nature, and a reminder that, although we can control some things, Mother Nature calls the shots...
So, the power of "chilling out"- the ability to exercise restraint; to not go crazy adding a ton of stuff all at once- is a huge and very, very important skill for all who play with botanicals to acquire.
I'll bet that you already have.
Stay creative. Stay curious. Stay excited. Stay restrained...
And Stay Wet.
As human beings, thankfully, each one of us is different. As hobbyists, this is especially true, and completely evident when one considers the wide variety of approaches we take to creating and managing our aquariums.
And, fish geeks being fish geeks, we all have our little idiosyncrasies and quirks. I know that I have some that get to me.
Like, a desire to make radical changes, seemingly out of the blue. Now, sure, I am the guy who gives a lot of his tanks and ideas plenty of time and space to "breathe" and develop over time. I'm pretty patient when it come to letting my tanks evolve.
However, I admit- I DO like to change stuff up sometimes.
Ever wake up one morning and...it just..hits you? That urge to change up your aquarium; it's look, "theme"- whatever?
I don't think that it's just a "me" thing, either.
It's part of being a fish geek, I think.
We look at our existing aquarium and say, "I really love it, but...."
We reach for some towels, grab a bucket, and it's on!
I think it's part of the mental makeup- the fabric, if you will- of the fish geek.
We're sort of almost "programmed" to want to switch stuff up after a while, right? It's like we want to create, modify, renew...or just try something different.
For many hobbyists, their one aquarium is the only one they can have- at least for now, but possibly forever. Space, economics, time, etc, all come into play, and there really isn't much you can do except work with the one you've got. I mean, it's a blessing to have even one...but to the serious fish geek, that desire to move on to a greener pasture (or should we say, "bluer river?")-to just taste some new stuff- seldom retreats.
Can you relate?
I think- think- that it's often augmented by my desire as the Tannin "mothership" and a need to continuously showcase new ideas and botanicals. Well, maybe that's an excuse.
But hey, we all love to try new stuff, right?
I know that I do.
And it's funny, because I think that even though I fancy myself as this restless "conceptual" guy who is constantly evolving his ideas, the reality is that my "makeovers" are seldom that radical- rather, their little iterations that represent incremental changes or improvements over previous designs.
I tend to "stay in my lane", and not stray all that far from it.
I almost envy those of you who can make radical changes at the spur of the moment without regret or a whole lot of consideration.
I often wonder why I play with such a tight set of characteristics- you know, certain wood arrangements, use of specific textures, colors, etc. Although I'm definitely prone to "over-analyzing" stuff at times, it's fun now and then to step out of my own mind and look at stuff as if I'm a "third party" of sorts.
Maybe I have that sort of "comfort zone" that I tend not to push myself out too far from. I mean, I operate in a pretty radical "sector" already- the blackwater, botanical-style world. It's not everyone's cup of tea, being pretty different from the conventional, "clear water" aquariums we all know so well. I realized a long term ago that, when I make changes to my tanks, they're almost always more like "iterations" of the existing concept.
Yeah, the "next steps" are often subtle in nature.
And I think that it's sort of "baked into" the idea of botanical-style aquariums: We set the stage for what nature does. Rather than trying to create a "finished product", I think those who operate in our arena tend to set the stage and let Nature do the rest of the work over time.
Interestingly, you can still make seemingly dramatic changes to your aquariums, and yet leave considerable parts of them intact and functional. This works great with botanical-style aquariums.
Nature does this all the time.
The idea of leaving the substrate and leaf litter/botanical "bed" intact as you "remodel" isn't exactly a crazy one. And conceptually, it's sort of replicates what occurs in Nature! Materials accumulate on top of other materials, facilitating new biological growth, continued foraging for resident fishes, and a more or less uninterrupted ecology.
Yeah, think about this for just a second.
As we almost constantly discuss, habitats like flooded forests (Igapo and Varzea), meadows, vernal pools, igarape, and swollen streams, which tend to encompass terrestrial habitats, or go through phases where they are terrestrial habitats- for a good part of the year.
In these wild habitats, the leaves, branches, soils, and other botanical materials remain in place, or are added to by dynamic, seasonal processes. For the most part, the soil, branches, and a fair amount of the more "durable" seed pods and such remain present during both phases.
The biggest "disruption" in these habitats is often the transformation from terrestrial to aquatic. However, the "hardscape" (to borrow an aquarium term) largely remains intact.
Sure, a "makeover" of an aquarium can be a seriously disruptive event (for both YOU and your fishes!).
On the other hand, if you take the mindset that this is a "transformation" of sorts, and act accordingly, it becomes more of an evolutionary process. This is something I've done for many years- like a lot of you have, and it not only makes your life a bit easier- it can create pretty good outcomes for the fishes we keep.
The "Urban Igapo" idea that I've been touting for a good part of the past 3 years is a very deliberate execution of this "iterative process", and it's taught me quite a bit about how these habitats function in Nature, and what kinds of benefits they bring to the aquarium.
We've talked about the idea of "flooding" an aquarium setup designed to replicate an Amazonian forest before. You know, sort of attempting to simulate some of the processes which happen seasonally in Nature. With the technology, materials, and information available to us today, the capability of creating a true "year-round" habitat simulation in the confines of an aquarium/vivarium setup has never been more attainable.
These are deliberate, more transformative executions by design.
However, making changes to every existing aquarium does not need to be a super-complicated, highly disruptive thing, right? I’m not advocating 360-degree changes in your aquarium management approach every time something doesn’t give you desired results in 3 days, or every time you're "not feeling it." That's a recipe for chaos.
What I am thinking about here is developing the "mental ability" to get yourself easily out of a situation that is simply not working for you- for the benefit of your animals, budget, time- and sanity. Shit, it’s a hobby, so if you’re not enjoying it, what’s the point?
So, maybe it’s not “move fast and break things” for you…perhaps it’s “move at a nice rate of speed and change moderately quickly when things don’t work out.”
What are the benefits of adopting a “move fast” philosophy- or at least the gist of it- for you as an aquarist?
First, you can test a lot of ideas and concepts on your tank relatively quickly, in “real time”, rather than just reading about them on the forums. If you have a general idea of where you want to go with your tank, but are interested in a few approaches, this is not a bad way to go.
You can work in multiple ideas to see if they work, and throw out the ones that don’t, relatively quickly. Now, again, I’m not talking about major hardware shuffles (“Yeah, the 350 was too small, so three weeks later, I broke it down and ordered a 700.” That’s pure insanity). Nope, I’m talking about “tweaks”, like deciding to feed your predatory fishes only at night- or a few days a week…or, perhaps dosing fertilizers only when the display is dark. Changing flow patterns, feeding times, light combinations. "Pulsing" leaf additions...Tweaking.
Not full-scale, drain-the-tank-and-start-from-scratch overhauls.
Second, you can certainly learn stuff at a more rapid clip, right? If you’re giving yourself the opportunity to “audition” a practice, philosophy, procedure, etc., you can find out if something makes sense a whole lot more than if you commit 1,000 percent to a rigid philosophy of “I’m only going to do it this way.”
Even if you don’t get the "whole picture" of what’s happening in your tank, attempting quick little experiments can give you an indication of the general direction or trend- an answer to a little piece of the puzzle that you can incorporate to evolve more successfully in the long term.
Finally, this philosophy actually can force you to look at things more "honestly."
In other words, if you decided to do something that maybe you thought might not work- by committing yourself to a “nothing is sacred” attitude at the start of your project, you can evaluate things in a more direct manner, and change things up as necessary to assure overall success of the tank and the health of its inhabitants. If you throw the “fun” part back into the equation, and share your trials and tribulations with other hobbyists, it certainly makes it more enjoyable to stop being stubborn and try to make things work, right?
Of course, for every action, there’s an equal and opposite reaction, right? So, what are the downsides to a rapid-iteration, “move fast and break things” philosophy?
To begin with, you will probably build some “mental debt.” In other words, as you rapidly make changes and move things along, you may tend to overlook other things. Human nature, right? You tend to look at every change or iteration as a big experiment, and that you can “fix stuff later”- a kind of dangerous trap to fall into, especially when you think of the potential impact on living organisms.
It’s one thing to make intelligent, measured changes, but to take shortcuts, non-sustainable work-arounds, and “band aids” harbors potential hidden dangers. Be alert to this. Your “pursuit of perfection” could result, ironically, in you never quite getting it right?
In addition, you might find yourself “burnt out” rather quickly. I mean, if you’re chaotically trying every new idea, every new gadget that’s out there in trying to find quick solutions, you will not likely enjoy this hobby for very long. It’s a marathon, not a sprint, right? I mean, it’s a “hobby” at the end of the day. Yet, each day I read forum posts from dozens of hobbyists who flail helplessly in multiple directions, trying every little thing to "change-up" their tank, in a desperate attempt to solve a relatively simple problem.
Algae issues are notorious for soliciting this kind of behavior- the desire to get the problem “solved” has resulted in many disasters (like using all sorts of chemicals and medications to eradicate algae, when the reality is that it could have been eradicated or managed with husbandry tweaks to begin with…). Some of these "fixes" result in a destroyed biome and dead fishes.
Think before you forge ahead with potentially long-term detrimental "fixes."
So, in summary. Changing stuff up- even relatively rapidly- isn't a bad thing, if it's done for the right reasons. Maybe it's "Aquatic A.D.D." or something (I have this theory, lol), but I think it can actually be a good thing. I even think I understand why some people change up their tanks so often.
With me, I suppose I could rationalize occasional bouts of this "fast change syndrome" by telling myself that it's a matter of wanting to try a lot of concepts out which get's me moving. The desire to move into different directions, despite having limited resources of space, time, or money.
Better to let the full range of your imagination inspire and guide you, instead of limit you. That's why I treasure thinking outside the box so much. Not because it's cool to just do things differently "because." Rather, it's because it's really important to follow up on some of those thoughts and ideas we have. Every single one has the potential to lead to some breakthrough or advancement in the hobby.
Use the relentless flow of ideas- and your ability to execute and accept change- to your advantage.
Every single one has potential.
Don't downplay those ideas that pop into your head from time to time, even if it means changing some stuff up. And they don't always have to be super well thought-out ideas, either.
Sometimes, you can play a "hunch", a "feeling", or a "whim"-and come up with something great.
Can't you think of at least a few things that you tried on a whim, only to realize later that they were incredible efforts that brought you so much joy?
I'll bet that you can.
Execute each one in it's own time. Let them breathe. Develop them. Or squash them quickly.
But do try them.
Because it's far better to do something than to just think about it, IMHO.
Consistency is important.
However, change can be good. Really good.
Stay dedicated. Stay focused. Stay reflective. Stay happy...
And Stay Wet.
One of the toughest things in the aquarium hobby is to face the possibility of losing fishes. When you think about it, the idea of keeping live tropical fishes in an aquarium is pretty incredible to begin with. What we take on isn't necessarily "difficult" in many instances. The techniques have been known and shared in the hobby for generations. However, the awesome thing is that we are able to obtain and maintain these organisms in the first place, right?
And when you add into the equation that are completely responsible for creating essentially the entire environment in which they reside, it becomes even more incredible, right? What we do is pretty special.
However, unlike keeping many other animals as"pets", like dogs, cats, hamsters, rabbits, etc., we have the unique ability to create representations- functional and aesthetic-of the natural habitats from which they come. We can do all sorts of environmental manipulations, and embrace all sorts of evolutions within their aquariums to represent aspects of their natural habitats.
And this ability brings with it a lot of opportunity to innovate, as well as the assumption of some risk.
Yeah, the process of creating, optimizing and managing a specialized aquatic habitat is subject to risk, whether we expect it or not.
The risk that we might not have acclimated our fishes correctly to the new environment that we have created. Risk that our management of the environment may not be be as controlled, consistent, or appropriate for the long-term health of the fishes.
This is not unique to the botanical-style aquarium, of course. It's something that we run into with all types of aquariums and fish-keeping endeavors, from the most basic goldfish bowl (arrghh!😂) to the most sophisticated reef aquarium system.
Risk permeates this hobby. It's something that is almost never discussed, but it is at the forefront of almost everything do. Risk abounds. We take risks every single time we purchase fish. And the responsibility to manage the risk- to mitigate any potential bad outcomes-lies squarely on our shoulders as hobbyists.
A classic, easy example? When repurchase that new fish, we immediately have to chose whether or not we will quarantine it before placing it into our tank. If we don't, we run the risk of introducing illness to our other healthy fishes. And, when we do quarantine (yay!),we STILL risk the possibility that the fish might not make it through. That it might not eat, or that a disease (the very reason you quarantine in the first place!) may manifest itself and possibly kill the fish in the quarantine system.
When we first started Tannin Aquatics, the idea of utilizing seed pods, bark, leaves, branches and stuff in aquariums to manipulate the environmental conditions wasn't completely unknown. Hobbyists have been doing it for generations to some extent. However, when we embarked on our mission to curate, test, and ultimately introduce new and different botanical materials into the hobby, we know it was a risk.
Some might have proven to be toxic to fishes. Some might have been collected from polluted environments that had noxious chemicals. Some might have been intended for other purposes, and sold to us by unscrupulous suppliers, who had them treated with laquers or other industrial chemicals. We found this out the hard way a few times, killing fishes in our test tanks in the process.
Horrible to lose innocent animals, but part of the challenge we accepted when we intended to become leaders in this new arena. Releasing untested materials to fellow fish keepers and killing them was not an option. We had to assume the risk of testing ourselves. Vetting of suppliers was, and continues to be, crucial. Good quality source material doesn't guarantee success- but it does mitigate some of the risk.
When we developed techniques for the preparation of botanicals for aquarium use, it was to help mitigate some of the risks that are inherent when you place natural terrestrial materials into a closed aquatic environment.
Yet, even with the development of "best practices" and recommended approaches and technique for safely utilizing botanicals in our aquariums, we knew that there was an even bigger, more ominous risk out there...Human nature.
Yes, when I started playing with botanicals in my aquariums almost two decades ago, I made a fair number of mistakes. Sometimes, they cost the lives of my fishes.
And killing fishes sucks.
Some mistakes were caused by my lack of familiarity with using various materials. Most were caused by not understanding fully the impact of adding botanical materials to a closed aquatic ecosystems. All were mitigated by taking the time to learn from them and honestly asses the good, the bad, and the practical aspects of using them in our aquariums.
And that meant developing "best practices" to help mitigate or eliminate issues as much as possible, even though the "practices" may not be the easiest, most convenient, or expedient way to proceed.
I KNEW that there would be people who might kill their fishes by adding lots of botanicals to their established systems without reading and following the instructions concerning preparation, cadence, and what to expect. I knew there would be people who would criticize the idea, "edit" the processes or recommended "best practices", talk negatively about the approach and generally scoff and downplay what they didn't know, understand, or do.
It's human nature whenever you give people something a bit different to play with...They want to go from 0-100 in like one day. And I knew that some of these people would go out on social media and attempt to trash the whole idea after they failed. This, despite all of our instructions, information, and pleas to follow the guidelines we suggested.
After more than six years of running Tannin, I have pretty much identified the two most common concerns we have for customers associated with utilizing botanicals in their aquariums. Curiously, our two biggest concerns revolve around our own human impatience and mindset- not the botanical materials themselves.
The first is... preparation.
We are often asked why we don't feel that you can, without exception, just give any of your botanicals "a quick rinse" and toss them into your aquarium.
After all, this is what happens in nature, right? Well, shit- yes...but remember, in most cases, there is a significant "dilution factor" caused by larger water volumes, currents, biologically-rich substrates, etc. that you encounter in natural aquatic systems. Even in smaller bodies of water, you have very "mature" nutrient export systems and biological equilibriums established over long periods of time which handle the influx and export of organic materials.
However, even in Nature, things go awry, and you will occasionally see bodies of water "fouled" by large, sudden influxes of materials (often leaves, grass clippings, etc.)- sometimes after rain or other weather events- and the result is usually polluted water, large algal blooms, and a pretty nasty smell!
In the aquarium, of course, you have a closed system with a typically much smaller water volume, limited import of fresh water, limited filtration (export) capacity, and in many cases, a less robust ecological microcosm to handle a large influx of nutrients quickly.
So you know where I'm going with this:
Fresh botanical materials, even relatively "clean" ones, are often still "dirty", from collection, storage, etc. They may have dust, airborne pollutants, soil or silt (depending upon where they were collected), even cobwebs, bird droppings, and dead insects (yuck!).
Natural materials accumulate "stuff." They're not sterile; made in some high tech "clean room" in a factory in Switzerland, right?
So," just giving botanicals a quick rinse" before tossing them in your tank is simply not good procedure, IMHO- even for stuff you collect from your own backyard. It's more risk to take on. At the very least, a prolonged (30 to 60 minute) steep in boiling hot water will serve to "sterilize" them to a certain extent. Follow it with a rinse to remove any lingering dirt or other materials trapped in the surfaces of your botanicals.
Now, I don't recommend this process simply because I want to be a pain in the ass. I recommend it because it's a responsible practice that, although seemingly "overkill" in some people's minds- increases the odds for a better outcome.
It reduces some of the risk.
The crew up in the cockpit on your flight from L.A. to New York know every system of the Boeing 737Max9 that they fly. But guess what? They still complete the pre-flight checklist each and every time they hop in the plane.
Because it can save lives.
Why should we be any different about taking the time to prepare botanicals? I know it sounds harsh; however, if you skip this step and kill your fishes- it's on you.
Why would you skip this, other than simply being impatient?
Could you get away with NOT doing this?
Sure. Absolutely. Many people likely do.
But for how long? When will it catch up with you? Maybe never...I know I'll get at least one email or comment from a hobbyist who absolutely doesn't do any of this and has a beautiful healthy tank with no problems.
Okay, good for you. I'm still going to recommend that, like I do- that you embrace a preparation process for every botanical item that you add to your aquariums.
Boiling/steeping also serves a secondary, yet equally important purpose: It helps soften and even break down the external tissues of the botanical, allowing it to leach out any remaining subsurface pollutants, sugars, or other undesirable organics to the greatest extent possible. And finally, it allows them to better absorb water, which makes them sink more easily when you place them in your aquarium.
Yes, it's an extra step.
Yes, it takes time.
However, like all good things in nature and aquariums, taking the time to go the extra mile is never a bad thing. And really, I'm trying to see what possible "benefit" you'd derive by skipping this preparation process?
Oh, let me help you: NONE.
There is simply no advantage to rushing stuff.
Like all things we do in our aquariums, the preparation of materials that we add to them is a process, and Nature sets the pace. The fact that we may recommend 30 minutes or more of boiling is not of concern to Nature. It may take an hour or more to fully saturate your Sterculia Pods before they sink.
So be it.
Savor the process. Enjoy every aspect of the experience. And don't you love the earthy scent that botanicals exude when you're preparing them?
And the shittiest thing? Even if you do all this prep, there is STILL risk that you will kill your fishes.
Damn, I'm not ever gonna make it as salesman, huh?
How much to use?
Well, that's the million dollar question.
Who knows? Even that is a guess and decidedly unscientific at best!
It all gets back to the (IMHO) absurd "recommendations" that have been proffered by vendors over the years recommending using "x" number of leaves, for example, per gallon/liter of water. There are simply far, far too many variables- ranging from starting water chem to pH to alkalinity, and dozens of others- which can affect the "equation" and make specific numbers unreliable at best.
Now, nothing is perfect.
Nothing we can tell you is an absolute guarantee of perfect results...You're dealing with natural materials, and the results you'll see are governed by natural processes that we can only impact to a certain extent by preparation before use. But it's a logical, responsible process that you need to embrace for long-term success.
It reduces some of the risk.
And, when it comes time to adding your botanicals to your aquarium, the second "tier" of this process is to add them to your aquarium slowly. Like, don't add everything all at once, particularly to an established, stable aquarium. Think of botanicals as "bioload", which requires your bacterial/fungal/microcrusacean population to handle them.
Bacteria, in particular, are your first line of defense.
If you add a large quantity of any organic materials to an established system, you will simply overwhelm the existing beneficial bacterial population in the aquarium, which will likely result in a massive increase in ammonia, nitrite, and organic pollutants. At the very least, it will leave oxygen levels depleted, and fishes gasping at the surface as the bacteria population struggles to catch up to the large influx of materials.
This is not some sort of esoteric concept, right? I mean, we don't add 25 3-inch fishes at once to an established, stable 10-gallon aquarium and not expect some sort of negative environmental consequence, right? So why would adding bunch of leaves, botanicals, wood, or other materials containing organics be any different?
So please, PLEASE add botanicals to your established aquarium gradually, while observing your fishes' reactions and testing the water parameters regularly during and after the process. Take measured steps.
There is no rush.
There shouldn't be.
It's interesting how the process of selecting, preparing and adding botanical materials to our aquariums has evolved over the time since we've been in business. Initially, as I discussed previously, it was all about trying to discover what materials weren't "toxic" in some way!
Then, it was about figuring out ways to prepare them and make sure that they don't pollute the aquarium. Finally, it's been about taking the time to add them in a responsible, measured matter.
I think our biggest "struggle" in working with botanicals is a mental one that we have imposed upon ourselves over generations of aquarium keeping: The need to control our own natural desire to get stuff moving quickly; to hit that "done" thing...fast.
And the reality, as we've talked about hundreds of times here and elsewhere, is that there really is no "finished", and that the botanical-style aquarium is about evolution. This type of system embraces continuous change and requires us to understand the ephemeral nature of botanicals when immersed in water.
I know I may be a bit "blunt" when it comes to these topics of preparation, practices, and patience- but they are critical concepts for us to wrap our heads around and really embrace in order to be successful with this stuff. And they are absolutely tied to the idea of reducing risk to the greatest extent possible.
All caveats and warnings aside, the art and evolving "science" of utilizing natural botanical materials for the purpose of enriching and influencing the environment of the aquarium is an exciting one, promising benefits and breakthroughs that we may not have even thought about yet!
It's okay to experiment...If we are willing to accept the additional risk.
We stress these points over and over an over, because I get questions every day from hobbyists asking if they really need to prepare their botanicals, and if it's safe to use "_____" in their tanks, etc.
This is indicative, to me, of larger problem in the aquarium hobby.
In a world where people are supposedly not able to retain more than 280 characters of information, and where there is a apparently a "hack" for pretty much everything, I wonder if have we simply have lost the ability to absorb information on things that are not considered “relevant” to our immediate goal. I say this not in a sarcastic manner, but in a thoughtful, measured one.
I'm baffled by hobbyists who want to try something new and simply do next to no research or self-education prior to trying it.
When you read some of the posts on Facebook or other sites, where a hobbyist asks a question which makes it obvious that they failed to grasp even the most fundamental aspects of their "area of interest", yet jumped in head-first into this "new thing", it just makes you wonder! I mean, if the immediate goal is to have "...a great looking tank with botanicals...", it seems to me that some hobbyists apparently don’t want to take the time to learn the groundwork that it takes to get there and to sustain the system on a long-term basis.
I suppose that it’s far more interesting- and apparently, immediately gratifying- for some hobbyists to learn about what gadgets or products can get us where we want, and what fishes are available to complete the project quickly.
This is a bit of a problem. It demonstrates a fundamental impatience, an unwillingness to learn, and a lack of desire to assume some responsibility or risk. The desire to pass the responsibility on to someone- or something- else when shit goes wrong.
And the reality is that it's really all on us.
When it comes to using botanicals- or, for that matter, embarking upon any aquarium-related speacialties, it's really important to contemplate them from the standpoint of reducing and accepting some risk. We, as aquarium hobbyists, are 100% responsible for the lives of the animals under our care. If we don't like the idea of accepting this responsibility, then we should consider another hobby. Simple as that.
I can talk about the "best practices" in our hobby until my face turns green. I can point out the benefits of making mental shifts and being patient endlessly. However, it's up to each one of us to accept- or reject- these ideas, and to accept the outcomes-positive or negative- of our choices about how we embrace-or reject-this stuff.
And, based on what I'm seeing and hearing, a lot of hobbyists simply don't feel that this applies to them.
Okay, I’m sounding very cynical. And perhaps I am. But the evidence is out there in abundance…and it’s kind of discouraging at times.
Look, I’m not trying to be the self-appointed "guardian of the hobby." I’m not calling us out. I’m simply asking for us to look at this stuff realistically, however. To question our habits. To accept responsibility for our actions. No one has a right to tell anyone that what they are doing is not the right way, but we do have to instill upon the newbie the importance of understanding the basics of our craft.
I'm super-proud that we've consistently elevated realistic discussions about unpopular topics related to our hobby sector. Yeah, we literally have blog and podcast titles like, "How to Avoid Screwing Up Your Tank and Killing all of Your Fishes with Botanicals" , or "There Will be Decomposition", or "Celebrating The Slimy Stuff."
If we are worried about risk, we need to take as many steps as possible to understand it. To mitigate it. Some steps are tedious. Unglamorous. Time consuming. Not very fun.
However, they are all steps that we need take to create better outcomes, and to help advance the state of the art of the aquarium hobby- for the benefit of us all.
Risk is part of the hobby. How we accept it, and take it on, is also part of the hobby. It doesn't have to be a dark cloud hanging over everything that we do. Rather, it should be a motivator, an opportunity to improve, and a means to grow.
Stay responsible. Stay curious. Stay engaged. Stay observant...
And Stay Wet.
One of the questions which we are asked less and less these days is, 'What kinds of fishes are suitable for a botanical-style aquarium?" I think that after 6 years of pounding all of these ideas into your heads about all of the strange nuances of botanical-style aquariums, it's almost universally understood that pretty much any fishes can live in them.
On the other hand, when it comes to how we stock our tanks, nothing has really changed...however, it could. And it should, IMHO.
We spend a pretty good amount of time studying, scheming, and pondering how to create a compatible, interesting, and attractive community of fishes within our aquariums.
It's probably among the most enjoyable things that we do in the hobby, right?
As a somewhat eccentric philosopher of all things fish, one of my favorite things to ponder is stuff that we do while creating our aquariums which is- intentionally or otherwise- analogous to the factors in Nature that result in the environments and fish populations that we find so compelling.
If you're like me, you likely spend a little too much time pondering all sorts of arcane aspects of the hobby...Okay, so maybe you're NOT like me, but you probably have a rather keen interest in the way Nature operates in the wild aquatic systems of the world, and stock your aquariums accordingly.
As one who studies a lot of details about some of the habitats from which our fishes come, I can't help but occasionally wonder exactly what it is that brings fishes to a given location or niche within a environment?
Now, the first answer we're likely to proffer is the most apparent...right? I mean, they follow the food!
Fishes tend to move into new areas in search suitable food sources as part of their life cycle. And food sources often become available in habitats such as flooded forest areas after the rains come, when decomposing leaves and botanical materials begin to create (or re-activate, as the case may be) "food webs", attracting ever more complex life forms into the area.
When we create our aquariums, we take into consideration a lot of factors, ranging from the temperament and size of our fish selections, to their appearance, right? These are all important factors. However, have you ever considered what the factors are in nature which affect the composition of a fish community in a given habitat?
Like, why "x" fish is living in a particular habitat?
What adaptations has the fish made that make it uniquely suitable for this environmental niche? Further, have you thought about how we as hobbyists replicate, to some extent, the actual selection processes which occur in Nature in our quest to create the perfect community aquarium?
Now, if you're an African Cichlid lover or reef hobbyist, I'm sure you have!
Social hierarchies, spatial orientations, and allopathic processes are vital to success in those types of aquariums; you typically can't get away with just throwing in a random fish or coral and hoping it will just mix perfectly.
However, for many hobbyists who aim to construct simple "community tanks", it isn't that vital to fill specific niches and such...we probably move other factors to the forefront when thinking about possible additions to our community of fishes: Like, how cool the fish looks, how large it grows, if it has a peaceful temperament, etc. More basic stuff.
However, in the end, we almost always make selections based upon factors which we deem important...again, a sort of near-mimicry of natural processes- and how the fishes work in the habitat we've created for them.
"Unnatural selection?" Or...Is it essentially what nature's does for eons?
Oh, and what exactly is an "aquatic habitat", by the way? In short, you could say that an aquatic habitat is the physical, chemical, and biological characteristics which determine the suitability for habitation and reproduction of fishes.
Of course, these characteristics can determine which fishes are found in a given area in the wild- pretty much without exception. It's been happening for eons.
Approaching the stocking of an aquarium by determining which fishes would be appropriate for the physical characteristics of the tank is not exactly groundbreaking stuff.
However, when we evaluate this in the context of "theme", and what fish would be found within, say, an Amazonian Igarape stream or a Southeast Asian peat swamp, the idea of adding fishes to "exploit" the features of the habitat we've created is remarkably similar to the processes which occur in Nature that determine what fish are found there, and it's the ultimate expression of good tank planning, IMHO.
It's just kind of interesting to think about in that context, right?
Competition is another one of the important factors in determining how fish populations in the wild. Specifically, competition for space, resources (e.g.; food) and mates are prevalent. In our aquariums, we do see this to some extent, right? The "alpha male" cichlid, the Pleco that gets the best cave, and the Tetra which dominates his shoal.
How we create the physical space for our fishes can have significant impact on this behavior. When good hiding spaces are at a premium, as are available spawning partners, their will be some form of social hierarchy, right?
Other environmental factors, such as water movement, dissolved oxygen, etc. are perhaps less impactful on our community once the tank is established. However, these factors figure prominently in our decisions about the composition of, or numbers or fishes in the community, don't they?
For example, you're unlikely to keep Hillstream loaches in a near stagnant, blackwater swamp biotope aquarium, just like you'd be unlikely to keep Altum Angelfish in a fast-moving stream biotope representation. And fishes which shoal or school will, obviously, best be kept in numbers.
"Aquarium Keeping 101", again.
One factor that we typically don't have in our aquaria is predation. I know very few aquarists who would be sadistic enough to even contemplate trying to keep predators and prey in the same tank, to let them "have at it" and see what happens, and who comes out on top!
I mean, there is a lot to this stuff, isn't there?
Again, the idea of creating a tank to serve the needs of certain fishes isn't earth-shattering. Yet, the idea of stocking the tank based on the available niches and physical characteristics is kind of a cool, educational, and ultimately very gratifying process. I just think it's truly amazing that we're able to actually do this these days.
And the sequence that you stock your tank in is extremely pertinent.
I think that you could literally create a sort of "sequence" to stocking various types of fishes based on the stage of "evolution" that your aquarium is in, although the sequence might be a bit different than Nature in some cases. For example, in a more-or-less brand new aquarium, analogous in this case to a newly-inundated forest floor, their might be a lot less in the way of lower life forms, such as fungi and bacteria, until the materials begin breaking down. You'd simply have an aggregation of fresh leaves, twigs, seed pods, soils, etc. in the habitat.
So, if anything, you're likely to see fishes which are much more dependent upon allochthonous input...food from the terrestrial environment. This is a compelling way to stock an aquarium, I think. Especially aquarium systems like ours which make use of these materials en masse.
Right from the start (after cycling, of course!), it would not be unrealistic to add fishes which feed on terrestrial fruits and botanical materials, such as Colossoma, Arowanna, Metynis, etc. Fishes which, for most aquarists of course, are utterly impractical to keep because of their large adult size and/or need for physical space!

Now, a lot of smaller, more "aquarium suited" fishes will also pick at these fruits and seeds, so you're not totally stuck with the big brutes if you want to go this route! Interestingly, the consumption and elimination of fruits by fishes is thought to be a major factor in the distribution of many plants in the region.
Do a little research here and you might be quite surprised about who consumes what in these habitats!
More realistically for most aquarists, I'd think that you could easily stock first with fishes like surface-dwelling (or near surface-dwelling) species, like hatchetfishes and some Pencilfishes, which are largely dependent upon terrestrial insects such as flies and ants, in Nature. In other words, they tend to "forage" or "graze" little, and are more opportunistic, taking advantage of careless insects which end up in the water of these newly-inundated environs.
I've read studies where almost 100 species were documented which feed near-exclusively on insects and arthropods from terrestrial sources in these habitats! As I mention often, if you dive a bit deeper than the typical hobbyist writings, and venture into scholarly materials and species descriptions, you'll be fascinated to read about the gut-content analysis of fishes, because they give you a tremendous insight about what to feed in the aquarium!
Continuing on, it's easy to see that, as the environments evolve, so does the fish population. And the possibilities for simulating this in the aquarium are many and are quite interesting!
Later, as materials start to decompose and are acted on by fungi and bacteria, you could conceivably add more of the "grazing" type fishes, such as Plecos, small Corydoras, Headstanders, etc.
As the tank ages and breaks in more, this would be analogous to the period of time when micro-crustaceans and aquatic insects are present in greater numbers, and you'd be inclined to see more of the "micropredators" like characins, and ultimately, small cichlids.
Interestingly, scientists have postulated that evolution favored small fishes like characins in these environments, because they are more efficient at capturing small terrestrial insects and spiders in these flooded forests than the larger fishes are!
And it makes a lot of sense, if you look at it strictly from a "density/variety" standpoint- lots of characins call these habitats home!
Then there are detritivores.
The detrivorus fishes remove large quantities of this material from submerged trees, branches, etc. Now, you might be surprised to learn that, in the wild, the gut-content analysis of almost every fish indicates that they consume organic detritus to some extent! And it makes sense...They work with the food sources that are available to them!
At different times of the year, different food sources are easier to obtain.
And, of course, all of the fishes which live in these habitats contribute to the surrounding forests by "recycling" nutrients locked up in the detritus. This is thought by ecologists to be especially important in blackwater inundated forests and meadows in areas like The Pantanal, because of the long periods of inundation and the nutrient-poor soils as a result of the slow decomposition rates.
All of this is actually very easy to replicate, to a certain extent, when stocking our aquaria. Why would you stock in this sort of sequence, when you're likely not relying on decomposing botanicals and leaves and the fungal and microbial life associated with them as your primary food source?
Well, you likely wouldn't be...However, what about the way that the fishes, when introduced at the appropriate "phase" in the tank's life cycle- adapt to the tank? Wouldn't the fishes take advantage of these materials as a supplement to the prepared foods that you're feeding them? Doesn't this impact the fishes' genetic "programming" in some fashion? Can it activate some health benefits, behaviors, etc?
I believe that it can. And I believe that this type of more natural feeding ca profoundly and positively impact our fishes' health.
I’m no genius, trust me. I don’t have half the skills many of you do but I have succeeded with many delicate “hard-to-feed” fishes over my hobby “career.”
Because I'm really patient.
Success with this approach is simply a result of deploying "radical patience." The practice of just moving really slowly and carefully when adding fishes to new tanks.
It's a really simple concept.
The hard part is waiting longer to add fishes.
Wait a minimum of three weeks—and even up to a month or two if you can stand it, and you will have a surprisingly large population of micro and macro fauna upon which your fishes can forage between feedings.
Having a “pre-stocked” system helps reduce a considerable amount of stress for new inhabitants, particularly for wild fishes, or fishes that have reputations as “delicate” feeders.
And think about it. This is really a natural analog of sorts. Fishes that live in inundated forest floors (yeah, the igapo again!) return to these areas to "follow the food" once they flood.
It just takes a few weeks, really. You’ll see fungal growth. You'll see some breakdown of the botanicals brought on by bacterial action or the feeding habits of small crustaceans and fungi. If you "pre-stock", you might even see the emergence of a significant population of copepods, amphipods, and other creatures crawling about, free from fishy predators, foraging on algae and detritus, and happily reproducing in your tank.
We kind of know this already, though- right?
This is really analogous to the tried-and-true practice of cultivating some turf algae on rocks either in or from outside your tank before adding herbivorous, grazing fishes, to give them some "grazing material."
Radical patience yields impressive results.
It’s not always easy to try something a little out of the ordinary, or a bit against the grain of popular practice, but I commend you for even thinking about the idea. At the very least, it may give you pause to how you stock your tank in the future, like "Herbivores first, micro predators last", or whatever thought you subscribe to.
Allow your system to mature and develop at least some populations of fauna for these fishes to supplement their diets with. You’ll develop a whole new appreciation for how an aquarium evolves when you take this long, but very cool road.
Stay patient. Stay observant. Stay creative. Stay studious. Stay resourceful...
And Stay Wet.
So, you have this idea for an aquarium.
You kind of see it in your head...you've assembled the materials, got it sort of together.
You add water.
Then, you walk in the room one day, look at it and- you just HATE it.
Like, you're done with it. Like, no re-hab on the design. No "tweaking" of the wood or whatever...You're just over the fucking thing. Ever felt that?
What do you do?
Well, I had this idea for a nano tank a while back. It seemed good in my head...I had it up for a nanosecond.
Even memorialized it with some Instagram Stories posts. Doing that is almost always the sort of thing that forces me to move on something...I mean, if you lay down a public "marker", you've got to go, right?
I thought that the tank would be a sort of "blank canvas" for an idea I had...I liked the idea, in principle.
But I didn't see a way forward with this one. I even took the extraordinary step of removing one element of the tank (the wood) altogether, in the hope of perhaps pivoting and just doing my "leaf only scape V3.0"- but I wasn't feeling it.
A stillborn idea. A tank not capable of evolving to anything that interested me at this time.
So...I let it go.
Yeah, made away with it. Shut it down. Terminated it...
Whatever you want to call it.
That's really a kind of extraordinary step for me. I mean, I'm sort of the eternal optimist. I try to make almost everything work if I can...
I mean, some of my favorite tanks evolved out of this mindset of sticking with something...We'll come back to that in bit.
Not this time, however.
I killed it.
Now, in the hours after the aborted aquarium move, I was actually able to gain some clarity about why I did it.
What made me do it?
I almost always do a sort of "post mortem" analysis when I abort on an idea, and this time was no different. It was pretty obvious to me...the "writing was on the wall" with this one!
I think it centered around two things that I simply can't handle in aquariums anymore.
1) I absolutely can't stand aquariums which don't have some sort of background- be it opaque window tint, photo paper, or paint. This tank had no background. You could see the window behind it, and the trees outside on the street, and...yeah.
2) I disdain seeing filters or other equipment in my aquariums. Like, I hate it more than you can ever even imagine. With really few exceptions, I simply hate seeing filters and stuff. It's only in recent years that I've been able to tolerate seeing filter returns in my all-in-one tanks...and just barely. Now, this nano had a little hang-on-the-back outside power filter...Which I not only saw from the top, but from behind...because-you got it- I didn't have a goddam background on the tank, yes.
I mean, am I that much of a primadonna that I can't handle that? I mean, maybe, but I like to think of it as a situation where I have simply developed an aesthetic sense that just can't tolerate some stuff anymore. I have good ideas, and then I get to equipment...and it sort of "stifles" them a bit.
This is weird.
Okay, yeah, maybe I am prima donna.
What could I have done to salvage this tank? Add a background?
Use a canister filter and glassware, you say?
Oh, sure. That's easy, right? I mean, all you see in the tank are these elegant curves of "lily pipes" and intakes...Maybe a surface skimmer...You just take 'em out and bleach 'em every once in a while and they stay nice and clean, and..
Okay, yeah. Great. On paper, anyways.
IMHO, glassware isn't the "organic art" that everyone seems to place on some lofty pedestal in the hobby. It reminds me of high school chemistry lab (which I think I got a C minus in, so some residual trauma there, no doubt). You think it's beautiful...I think it's simply dreadful.
It's another piece of equipment, which you see on the outside of the tank, too, with its "umbilical" of return lines shooting up along the sides. Now sure, I know these were developed to make an obvious, visible necessity (filter returns) more elegant and beautiful...However, to me, they're just that- obvious, visible, distracting...and ugly.
Hell, I've even made crazy efforts to hide the canister filters beneath my tanks before, when I couldn't hide them within the tank. It's like, I had to do something!
I know, I'm being waaaaay too stupid about this.
Because, really, with a lot of my reef aquarium work, and for that matter, some of my fave botanical-style tanks, you can see some of this stuff. When you see my next reef tank, you might see couple of submersible pumps in the tank , low and deep behind the rock work.
For some reason, it doesn't completely fry my brain in every single situation. I suppose it's a hypocritical thing, but man, sometimes it freaks me out and sometimes I can give it a pass.
Like, why do some tanks get a pass, and others just freak me out with this stuff.
I think, maybe, it's about the "concept"of the tank. Or the context. Like, some of my fave ever tanks, like my leaf-litter-only tanks, typically will have some equipment evident, because they are essentially a "zero-releaf" aquascape, with nothing that you can hide this stuff behind, like wood or rocks, or whatever. It's as "honest" as it gets. If you want to filter and heat the tank, you only have few options.
It never bothered me all that much in those types of tanks.
Yet, in other tanks? Just fugettaboutit!
Yeah, it MUST be about the concept of the tank. Not only will I forgive the visible equipment, sometimes I'll forgive myself the entire poor execution, too. Because, when I look back at some of the stuff I've done, that was definitely the mindset. Like, I was just happy to sort of pull it off, despite how crappy it looked, as this little gem from 2004 graphically illustrates:
Now that I look back on it, there were actually tons of times when I just let a tank evolve, unmolested and unhurried, because something spoke to me...no matter how weird or seemingly dumb the concept may have initially appeared. There was something about it that I believed in...
And occasionally, I'll try something, tear it down, and just regret it. Like, I'll realize, too late, that there was something I liked about the idea, and that I should have kept at it; let it do it's thing.
Like, what IF I kept it in play for little longer?
I mean, could it have evolved into something cool?
I recall a particular experiment I did with Spider Wood, which I let go very early in the game. The arrangement was almost a "reef like" concept...It didn't look right at the time, so I killed it way too early.
Like, a few tweaks to the wood stack, a buildup of substrate in the back of it, a buildup of some leaves and maybe some plants in the back, and it could have been a respectable recreation of the banks of some of the forest floor streams that I've seen in South America.
Yeah, I'd love to try that one again.
Then there were others which I had great faith in right from the start. Even though they looked a bit weird initially, I knew that they'd evolve into something special if I let them be.
Some just hit the right note, despite a possibly shaky start. Just knew that the idea was so special, that given the space and time, they'd eventually hit the right notes...And they did.
And, then, there were those ideas which, despite their unconventional appearance, were iconic to me, because they represented the culmination of although experiment; a transformation from research to idea to reality. Stuff which created a real transformation in the way I look at aquariums. The "Urban Igapo" style aquairums that many of us execute now, arose from just such an idea.
Sometimes, you just know it. You just feel that letting go of your preconceptions, doubts, and fears, rather than letting go of the tank-is just the right move.
Regardless of the idea, or the appearance of your tank, if there is any way to salvage what you feel is a great idea- even if it means just waiting it out for awhile- do it.
You just never know if that one "not so good"idea will turn out to be the one that changes everything for you, and inspires others in the process. Your "fail" might be the unlock- the key- for someone else who was about give up, and then suddenly saw something in your work, and created a tank based on your "failed" concept- executed on an idea-which truly touched others in ways you might not have even thought of.
So, yeah- let go...in the right way.
Stay bold. Stay patient. Stay creative. Stay optimistic. Stay enthusiastic. Stay persistent...
And Stay Wet.
