Of all the fun topics in botanical-style aquarium keeping, few hold my interest as much as substrates.
I imagine the substrate as this magical place which fuels all sorts of processes within our aquariums, and that Nature tends to it in the most effective and judicious manner.
Yeah, I'm a bit of a "substrate romantic", I suppose.😆
Particularly in transitional habitats, like flooded forests, etc. the composition and characteristics of the substrate plays a huge role in the ecology of the aquatic habitat. The presence of a lot of soils, clays, and sediments in these substrates, as opposed to just sand, creates a habitat which provides a lot of opportunity for organisms to thrive.
The substrates are not just "the bottom."
They are diverse harbors of life, ranging from fungal and biofilm mats, to algae, to epiphytic plants. Decomposing leaves, seed pods, and tree branches compose the substrate for a complex web of life which helps the fishes we're so fascinated by to flourish. And, if you look at them objectively and carefully, they are beautiful.
Detritus ("Mulm") located in the sediments is the major source of energy and/or nutrients for many of these dynamic aquatic habitats. The bacteria which perform all the important chemical reactions, such as converting ammonia to nitrite, nitrates to nitrogen, releasing bound-up nutrients, neutralizing hydrogen sulfide, etc. will obtain essential nutrients from the detritus (this is what autotrophic bacteria that metabolize ammonia/ammonium or hydrogen sulfide for energy do).
These bacteria may also "harvest" those nutrients, as well as metabolize (aerobically or anaerobically) the organic compounds present in the detritus for energy, just like heterotrophs do.
The processing of nutrients in the aquarium is a fascinating one; a real "partnership" between a wide variety of aquatic organisms.
Yes, there is a lot of amazing biological function occurring in these layers. And of course, fostering this dynamic in the aquarium is one of the things we love the most. It's all part of our vision for the modern, botanical-style aquarium.
Now, hobbyists have played with deep sand beds and mixes of various materials in aquariums for many years, and knowledgable proponents of natural aquarium management, such as Diane Walstad, have discussed the merits of such features in far more detail, and with a competency that I could only dream of! That being said, I think the time has never been better to experiment with this stuff!
Again, we're talking about utilizing a wider variety of materials than just sand, so the dynamics are quite different, offering unique functions, processes, and potential benefits.
I've been thinking through further refinements of the "deep botanical bed"/sand substrate relationship. I've been spending a lot of time over the years researching natural aquatic systems and contemplating how we can translate some of this stuff into our closed system aquaria.
Before we talk about the actual substrate materials again, let's think about the processes that we would like to foster in a substrate, and the potential negatives that may be of concern to those of us who play with botanicals in our substrate configurations
One of the things that many hobbyists ponder when we contemplate creating deep, botanical-heavy substrates, consisting of leaves, sand, and other botanical materials is the buildup of hydrogen sulfide, CO2, and other undesirable compounds within the substrate.
Well, it does make sense that if you have a large amount of decomposing material in an aquarium, that some of these compounds are going to accumulate in heavily-"active" substrates. Now, the big "bogeyman" that we all seem to zero in on in our "sum of all fears" scenarios is hydrogen sulfide, which results from bacterial breakdown of organic matter in the total absence of oxygen.
Let's think about this for just a second.
In a botanical bed with materials placed on the substrate, or loosely mixed into the top layers, will it all "pack down" enough to the point where there is a complete lack of oxygen and we develop a significant amount of this reviled compound in our tanks? I think that we're more likely to see some oxygen in this layer of materials, and I can't help but speculate- and yeah, it IS just speculation- that actual de-nitirifcation (nitrate reduction), which lowers nitrates while producing free nitrogen, might actually be able to occur in a "deep botanical" bed.
And it's certainly possible to have denitrification without dangerous hydrogen sulfide levels. As long as even very small amounts of oxygen and nitrates can penetrate into the substrate, this will not become an issue for most systems. I have yet to see a botanical-style aquarium where the material has become so "compacted" as to appear to have no circulation whatsoever within the botanical layer.
Now, sure, I'm not a scientist, and I base this on close visual inspection of numerous aquariums, and the basic chemical tests I've run on my systems under a variety of circumstances. As one who has made it a point to keep my botanical-style aquariums in operation for very extended time frames, I think this is significant. The "bad" side effects we're talking about should manifest over these longer time frames...and they just haven't.
We need to look at substrates literally as an aquatic organism. And, like aggregations of organisms, they may be diverse, both morphologically and ecologically. They're a dynamic, functional part of the miniature ecosystems we create in our aquariums. We've used the "basic" stuff for a generation. It's time to open up our minds to a few new ideas. To rethink substrate. To reconsider why we incorporate substrate, and what we use.
What kinds of materials can we employ to create more "functional" substrates (which just happen to look cool, too?). What kinds of functions and benefits can we hope to recreate in the confines of our aquariums?
First off, think beyond just sands...or anything resembling "conventional" aquarium substrate. Think about what goes on in the benthic (bottom) regions in the natural habitats we love, and what benefits or support the materials which aggregate there provide for the organisms within the ecosystem.
Understand that the substrate is a dynamic, extremely important part of the aquarium, too. And what we construct our substrate with, and how we manage it, is of profound importance to our fishes!
Fostering fungal growth, as well as other microorganisms and small crustaceans, should be a huge component of the "why" we do this. These organisms, as we've discussed repeatedly, form a part of the "food chain" within our captive ecosystems, and offer huge benefits to the aquarium not only as potential supplemental nutrition for fishes, but as a means to process and export nutrients from within the botanical-style aquarium.
So, yeah, in summary- the substrate plays a huge role in the function of a botanical-style aquarium. We can create a "facility" with substrate materials which provides not only unique aesthetics- it provides priceless benefits: Production of supplemental nutrition for our fishes, and nutrient processing via a self-generating population of creatures that compliment, indeed, create the biodiversity in our systems on a more-or-less continuous basis.
True "functional aesthetics!"
A combination of finely crushed leaves, bits of botanicals, small twigs, etc. can form the basis for a more "biologically active" and even productive substrate. As these materials break down, they are colonized by fungi and biofilms, and impart tannins, lignin, and other sources of carbon into the water to fuel a variety of microbial growth.
As you might have gathered by now, we are an advocate of some rather "unconventional" substrate materials, particularly a classification what we call "Sedimented Substrates."
Yeah, that'd be ours. NatureBase "Igapo", "Varzea", and the upcoming "Mangal", "Floresta" and "Selagor", are examples of substrates which have a lot of sediments and clays in their formulation. These substrates realistically replicate the composition, function, and look of soils which are found in many tropical aquatic habitats.
In fact, most of our NatureBase substrates have a significant percentage of clays and sediments in their formulations. These materials have typically been something that aquarists have avoided, because they will cloud the water for a while, and often impart a bit of color. Like, that's a problem? We also have some botanical components in a few of our substrates, because they are intended to be "terrestrial" substrates for a while before being flooded...and when this stuff is first wetted, some of it will float. And that means that you're going to have to net it out, or let your filter take it out.
You simply won't have that "issue" with your typical bag of aquarium sand!
You can mix them with any of the above-mentioned commercially-available sands, or use them alone. You can gradually add water (as in our "Urban Igapo" concept), or simply fill your tank form day one. Expect significant cloudiness for several days as the materials settle out, though. Don't rinse these substrates...just put them to work right away.
Now, although you can (and should) play with these substrates "wet" from the start, I'd be remiss if I didn't remind you again that the igapo and varzea substrates were initially intended to be "terrestrial" for a period of time, to get the grasses and plants going, and then inundated.
So, yeah, you'll have to make a mental shift to appreciate a different look and function. And many hobbyists simply can't handle that. We've been up front with this stuff since these products were released, to ward off the, "I added NatureBase to my tank and it looks like a cloudy mess! This stuff is SHIT!" type of emails that inevitably come when people don't read up first before they purchase the stuff.
And the warning and mental shift indoctrinations have worked. No one has freaked out.
Instead, we're hearing how incredibly natural these aquariums look, and how the biological diversity and stability of these tanks are.
What goes on in an aquarium with sediments, botanicals- or leaves, in this instance as the total "substrate" or "hardscape", as the case may be, is that they become the basis for biological activity in the tank. As we have discussed a million times here, as botanicals break down, they recruit bacteria, fungi, and other organisms on their surfaces.
That's the "big deal" about substrates.
Mix it up. Play with sediments, crushed leaves, broken bits of botanicals..All sorts of natural "stuff" which would previously have been considered "dirty" and "bad for long term maintenance" in almost anyone's book. Look at the advantages that can be realized, instead of the potential risks involved in experimenting.
Open your mind up to accept the look and function- and the "aesthetic challenges" of using non-traditional materials in your substrates.
Stay creative. Stay excited. Stay bold. Stay studious...
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.
Part of the aquarium hobby experience is screwing stuff up.
There are so many things that we do as aquarists which involve variables beyond our control, that failure in some things is almost inevitable.
And, after a lifetime in the hobby, I will occasionally reflect back on some of the great successes that I’ve had...and on some of the many, many failures that I’ve been involved with! Failures aren’t that bad, really. In fact, they're pretty damn helpful...As the sayings goes, “Nothing is ever wasted- it can always serve as an example of what NOT to do!”
Yeah, because if you learn from them, failures or disasters are extremely valuable tools for self-education.
I was thinking about my worst-ever aquarium disasters, and, fortunately, there have not been all that many...However, the ones I have had have been notable...and very educational!
My biggest mistakes came out of my own arrogance, really. Yes, arrogance. A desire to flaunt the "rules" set by Nature.
Usually, they were "created" when I tried to do something that disregarded simple logic (and a century of aquarium common sense), like trying mixes of fishes that were absurd, or overstocking tanks...stuff like that.
For example, from my reef keeping experience- not all that many years ago, actually- I was going to be the ONE reefer to keep several Centropyge angelfish in his reef, including a Lemonpeel, Vrolicki, Coral Beauty, Flame Angel, and Bicolor! If you don't know anything about the dwarf angelfish of the genus Centropyge, the one thing you SHOULD know is that they are very territorial, and don't generally get along with others of their own species. And mixing different species is a traditional "recipe" for disaster.
Oh, and most of the ones I wanted to keep had a well-earned reputation for snacking on coral tissue...What could go wrong here?
This was a recipe for failure that even the most inexperienced reefer could see coming. Of course, I was "experienced", so I knew better, right?
Nonetheless, I really thought I could pull this off in a large reef with specialized aquascaping... I was convinced that it could work and that I'd be the envy of the reef aquarium world for doing so...Not only did this experiment end with some "predictable" results (a lot of nice corals getting snacked on), it resulted in 5 very ticked-off, very beaten up dwarf angels! No shit? Who would have seen that coming, right?
Just plain stupid...For some reason, I really thought that my “methodology” would pay off and that it could work...WRONG.
But hey. I did it. I failed at it. I OWN it.
I distinctly remember a dubious experiment on the side of my parents' house one summer when I was a teen, attempting to culture mosquito larvae...yeah, you know how well THAT went down! I think that was the most mosquito bites I've ever had in one summer...
But I learned my lesson....
Or the time I tried to build my own fluidized reactor. It sounded like noble project, but the reality was that I started with a bad concept and used cheap PVC materials that didn't quite match up. Yeah, it didn’t work, and the resulting leaks and total lack of functionality reflected my DIY "skills!" It was a good thought, but really poor on the "execution" side.
Completely unlike the Angelfish fiasco, which was a “lose-lose” proposition! Nowadays, if I have the urge to do DIY, I simply break out the credit card and purchase whatever it is I was thinking of making. Aquarium equipment manufacturers LOVE me!
Another lesson learned.
Oh, or there was that time I tried to make a continuous-feed brine shrimp hatcher...Shit, do you know how LONG it takes to get brine shrimp eggs out of the water column in your tank?
A really long time.
However, failing- and I mean this in the most literal sense- can actually be beneficial in so many ways, especially if you share your failures publicly. Right now, somewhere out in the aquarium hobby world, there is another hobbyist contemplating one of the same absurd, disaster-inevitable ideas that you brought to life...
Perhaps it's not some huge, epic-disaster-bound system failure...Maybe, it's just something that's a bad decision; one that should be aborted on, but isn't likely to be- and the outcome is already well known in the hobby...
Maybe it's in our nature as hobbyists; we just love to tempt fate. And look, I get it...I've written on these very pages that sometimes, we need to go against the grain and try new ideas.
Even after 6 years of pushing this idea of botanical-style aquariums, we're still learning some new ideas, creating "best practices", and evolving techniques. We still make a few mistakes. And, like many hobbyists, we're still trying to get our heads around the "big picture" of the approach, which seems so contradictory to what has been passed down as "the way to do stuff" in the hobby for generations.
It makes many people uncomfortable to take leaps of faith. And, sure, despite the successful implementation of these techniques for several years by thousands of hobbyists, there is always a chance of failure.
It's scary. It can be viewed as "irresponsible" by some. At the very least, you might question the efficacy and safety of some of this stuff.
It makes sense.
We ask you to make a lot of mental shifts accept some ideas which seem to go "against the grain" of long-held hobby "best practices" and philosophies of aquarium management.
We ask you to understand what you are doing what you are doing, and what the rationale behind the approach is.
One thing that you do get when ideas are shared like this is the benefit of the body of work; the experience- good and bad- of a large community of hobbyists who have went down this same path. The key to taking an idea from "fringe" to "best practice" is sharing.
Sharing of mistakes made, the refinements done, and the "tweaks" that yielded consistent success.
It starts by creating a hobby culture of sharing.
Sharing of our mistakes is every bit as important as sharing our amazing successes.
So imagine, for a moment, if you do a quick “confessional” post on Instagram or Facebook about your biggest aquarium screw up, and just one hobbyist who is contemplating a similar thing stumbles on it, and then decides NOT to recreate your disaster!
Think of the savings in money, frustration, and innocent animals’ lives...It’s all good. "Failure" makes you a more successful aquarist- IF you learn from the mistake, and IF you share it with others!
It's kind of fun, too!
So, don’t hide your failures.
Trumpet them from the highest mountain. Savor them. Run around, scream, share, yell at people if you must...But tell ‘em that you screwed something up...Tell them how, why, and what it was that you did to screw it up!
Then laugh about it and feel better! Look at the absurdity of the thing you did.
Of course, some seemingly counter-intuitive ideas do work.
Sometimes, you try something that YOU think will be a mess, but your friends know will work, because they've done it many times, and have refined the idea and practices. You're a bit scared...and you do it anyways based on their ideas! And it DOES work! Like recently, when my friend convinced me to try several male Apistos of different species in my display tank...I was like, "Dude...really?"
And he said, "Trust me." And I did. And it was awesome!
Think about "failure" in the context of the bigger picture...
The neat thing about mistakes, screw-ups, and "failures" is that they often lead to something far, far better than whatever it was that you initially failed at. Because, if you take the time to ask yourself why it happened, and reconstruct the process, and make necessary adjustments and recalibration, you'll often find that the idea can work- just in a slightly different manner than you originally thought.
And failures are only failures if you don't learn from them.
Even in our business, we screw up shit all the time, and usually it's our own fault. And we try to learn from them and refine our processes to make sure that they don't happen again.
In fact, I've been working on a piece on the many screw-ups we’ve made here at Tannin. It’s actually kind of funny, because there ARE so many!
"Marketing blasphemy", you say? No. Not at all. Rather, it’s a living embodiment of practicing what we preach...
As humans, we all make bad decisions from time to time. Some are the result of pushing boundaries...others are simply bad judgement. Again, how the mistake was made isn't quite as important as learning from it is.
We will all benefit from being human, being honest, and getting through our trials and tribulations in fish keeping together. And yeah, we all have more to gain than to lose from sharing our mistakes.
What’s the biggest screwup- the worst mistake- that you’ve made in aquarium keeping? What did you learn from it?
Don’t be shy. Own it. Share it. Your "failure" will likely lead to others succeeding...So, it wasn’t really a failure after all, right?
Stay bold. Stay thoughtful. Stay honest. Stay curious. Stay experimental...
And Stay Wet.
A big thought about our botanical-style aquariums:
The aquarium-or, more specifically- the botanical materials which comprise the botanical-style 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 utilize the organic compounds present in the water as a nutritional source.
Oh, the part about the biofilms and fungal growths sounds familiar, doesn't it?
Let's talk about our buddies, the biofilms, just a bit more. One more time. Because nothing seems as contrary to many hobbyists than to sing the praises of these gooey-looking strands of bacterial goodness!
Structurally, biofilms are surprisingly strong structures, which offer their colonial members "on-board" nutritional sources, exchange of metabolites, protection, and cellular communication. They form extremely rapidly on just about any hard surface that is submerged in water.
When I see aquarium work in which biofilms are considered a "nuisance", and suggestions that it can be eliminated by "reducing nutrients" in the aquarium, I usually cringe. Mainly, because no matter what you do, biofilms are ubiquitous, and always present in our aquariums. We may not see the famous long, stringy "snot" of our nightmares, but the reality is that they're present in our tanks regardless.
The other reality is that biofilms are something that we as aquarists typically fear because of the way they look. In and of themselves, biofilms are not harmful to our fishes. They function not only as a means to sequester and process nutrients ( a "filter" of sorts?), they also represent a beneficial food source for fishes.
Now, look, I can see rare scenarios where massive amounts of biofilms (relative to the water volume of the aquarium) can consume significant quantities of oxygen and be problematic for the fishes which reside in your tank. These explosions in biofilm growth are usually the result of adding too much botanical material too quickly to the aquarium. They're excaserbated by insufficient oxygenation/circulation within the aquarium.
These are very unusual circumstances, resulting from a combination of missteps by the aquarist.
Typically, however, biofilms are far more beneficial that they are reven emotely detrimental to our aquariums.
Nutrients in the water column, even when in low concentrations, are delivered to the biofilm through the complex system of water channels, where they are adsorbed into the biofilm matrix, where they become available to the individual cells. Some biologists feel that this efficient method of gathering energy might be a major evolutionary advantage for biofilms which live in particularly in turbulent ecosystems, like streams, (or aquariums, right?) with significant flow, where nutrient concentrations are typically lower and quite widely dispersed.
Biofilms have been used successfully in water/wastewater treatment for well over 100 years! In such filtration systems the filter medium (typically, sand) offers a tremendous amount of surface area for the microbes to attach to, and to feed upon the organic material in the water being treated. The formation of biofilms upon the "media" consume the undesirable organics in the water, effectively "filtering" it!
Biofilm acts as an adsorbent layer, in which organic materials and other nutrients are concentrated from the water column. As you might suspect, higher nutrient concentrations tend to produce biofilms that are thicker and denser than those grown in low nutrient concentrations.
Those biofilms which grow in higher flow environments, like streams, rivers, or areas exposed to wave action, tend to be denser in their morphology. These biofilms tend to form long, stringy filaments or "streamers",which point in the direction of the flow. These biofilms are characterized by characteristic known as "viscoelasticity." This means that they are flexible, and stretch out significantly in higher flow rate environments, and contract once again when the velocity of the flow is reduced.
Okay, that's probably way more than you want to know about the physiology of biofilms! Regardless, it's important for us as botanical-style aquarists to have at least a rudimentary understanding of these often misunderstood, incredibly useful, and entirely under-appreciated life forms.
And the whole idea of facilitating a microbiome in our aquariums is predicated upon supplying a quantity of botanical materials- specifically, leaf litter, for the beneficial organisms to colonize and begin the decomposition process. An interesting study I found by Mehering, et. al (2014) on the nutrient sequestration caused by leaf litter yielded this interesting little passage:
"During leaf litter decomposition, microbial biomass and accumulated inorganic materials immobilize and retain nutrients, and therefore, both biotic and abiotic drivers may influence detrital nutrient content."
The study determined that leaves such as oak "immobilized" nitrogen. Generally thinking, it is thought that leaf litter acts as a "sink" for nutrients over time in aquatic ecosystems.
Oh, and one more thing about leaves and their resulting detritus in tropical streams: Ecologists strongly believe that microbial colonized detritus is a more palatable and nutritious food source for detritivores than uncolonized dead leaves. The microbial growth which occurs on the leaves and their resulting detritus increases the nutritional quality of leaf detritus, because the microbial biomass on the leaves is more digestible than the leaves themselves (because of lignin, etc.).
Okay, great. I've just talked about decomposing leaves and stuff for like the 11,000th time in "The Tint"; so...where does this leave us, in terms of how we want to run our aquariums?
1) Add a significant amount of leaf litter, twigs, and botanicals to your aquarium as part of the substrate.
2) Allow biofilms and fungal growths to proliferate.
3) Feed your fishes well. It's actually "feeding the aquarium!"
4) Don't go crazy siphoning out every bit of detritus.
Let's look at each of these points in a bit more detail.
First, make liberal use of leaf litter in your aquarium. I'd build up a layer anywhere from 1"-4" of leaves. Yeah, I know- that's a lot of leaves. Initially, you'll have a big old layer of leaves, recruiting biofilms and fungal growths on their surfaces. Ultimately, it will decompose, creating a sort of "mulch" on the bottom of your aquarium, rich in detritus, providing an excellent place for your fishes to forage among.
Allow a fair amount of indirect circulation over the top of your leaf litter bed. This will ensure oxygenation, and allow the organisms within the litter bed to receive an influx of water (and thus, the dissolved organics they utilize). Sure, some of the leaves might blow around from time to time- just like what happens in Nature. It's no big deal- really!
The idea of allowing biofilms and fungal growths to colonize your leaves and botanicals, and to proliferate upon them simply needs to be accepted as fundamental to botanical-style aquarium keeping. These organisms, which comprise the biome of our aquariums, are the most important "components" of the ecosystems which our aquariums are.
I'd be remiss if I didn't at least touch on the idea of feeding your aquarium. Think about it: When you feed your fishes, you are effectively feeding all of the other life forms which comprise this microbiome. You're "feeding the aquarium." When fishes consume and eliminate the food, they're releasing not only dissolved organic wastes, but fecal materials, which are likely not fully digested. The nutritional value of partially digested food cannot be understated. Many of the organisms which live within the botanical bed and the resulting detritus will assimilate them.
Now, we could go on and on about this topic; there is SO much to discuss. However, let's just agree that feeding our fishes is another critical activity which provides not only for our fishes' well-being, but for the other life forms which create the ecology of the aquarium.
And, let's be clear about another thing: Detritus, the nemesis of many aquarists- is NOT our enemy. We've talked about this for several years now, and I cannot stress it enough: To remove every bit of detritus in our tanks is to deprive someone, somewhere along the food chain in our tanks, their nutritional source. And when you do that, imbalances occur...You know, the kinds which cause "nuisance algae" and those "anomalous tank crashes."
The definition of this stuff, as accepted in the aquarium hobby, is kind of sketchy in this regard; not flattering at the very least:
"detritus is dead particulate organic matter. It typically includes the bodies or fragments of dead organisms, as well as fecal material. Detritus is typically colonized by communities of microorganisms which act to decompose or remineralize the material."
Shit, that's just bad branding.
The reality is that this not a "bad" thing. Detritus, like biofilms and fungi, is flat-out misunderstood in the hobby.
Could there be some "upside" to this stuff?
Of course there is.
I mean, even in the above the definition, there is the part about being "colonized by communities of microorganisms which act to decompose or remineralize..."
It's being processed. Utilized. What do these microorganisms do? They eat it...They render it inert. And in the process, they contribute to the biological diversity and arguably even the stability of the system. Some of them are utilized as food by other creatures. Important in a closed system, I should think.
This is really important. It's part of the biological operating system of our botanical-style aquariums. I cannot stress this enough.
Now, I realize that the idea of embracing this stuff- and allowing it to accumulate, or even be present in your system- goes against virtually everything we've been indoctrinated to believe in about aquarium husbandry. Pretty much every article you see on this stuff is about its "dangers", and how to get it out of your tank. I'll say it again- I think we've been looking at detritus the wrong way for a very long time in the aquarium hobby, perceiving it as an "enemy" to be feared, as opposed to the "biological catalyst" it really is!
In essence, it's organically rich particulate material that provides sustenance, and indeed, life to many organisms which, in turn, directly benefit our aquariums.
We've pushed this narrative many times here, and I still think we need to encourage hobbyists to embrace it more.
Okay, I'll admit that detritus, as we see it, may not be the most attractive thing to look at in our tanks. I'll give you that. It literally looks like a pile of shit! However, what we're talking about allowing to accumulate isn't just fish poop and uneaten food. It's broken-down materials- the end product of biological processing. And, yeah, a wide variety of organisms have become adapted to eat or utilize detritus.
There is, of course, a distinction.
One is the result of poor husbandry, and of course, is not something we'd want to accumulate in our aquariums. The other is a more nuanced definition.
As we talk about so much around here- just because something looks a certain way doesn't mean that it alwaysa bad thing, right?
What does it mean? Take into consideration why we add botanicals to our tanks in the first place. Now, you don't have to have huge piles of the stuff littering your sandy substrate. However, you could have some accumulating here and there among the botanicals and leaves, where it may not offend your aesthetic senses, and still contribute to the overall aquatic ecosystem you've created.
If you're one of those hobbyists who allows your leaves and other botanicals to break down completely into the tank, what really happens? Do you see a decline in water quality in a well-maintained system? A noticeable uptick in nitrate or other signs? Does anyone ever do water tests to confirm the "detritus is dangerous" theory, or do we simply rely on what "they" say in the books and hobby forums?
Is there ever a situation, a place, or a circumstance where leaving the detritus "in play" is actually a benefit, as opposed to a problem?
I think so. Like, almost always.
Yes, I know, we're talking about a closed ecosystem here, which doesn't have all of the millions of minute inputs and exports and nuances that Nature does, but structurally and functionally, we have some of them at the highest levels (ie; water going in and coming out, food sources being added, stuff being exported, etc.).
There is so much more to this stuff than to simply buy in unflinchingly to overly-generalized statements like, "detritus is bad."
The following statement may hurt a few sensitive people. Consider it some "tough love" today:
If you're not a complete incompetent at basic aquarium husbandry, you won't have any issues with detritus being present in your aquarium.
Don't neglect regular water exchanges.
Don't fail to maintain your equipment.
Don't ignore what's happening in your tank.
This is truly not "rocket science." It's "Aquarium Keeping 101."
And it all comes full circle when we talk about "filtration" in our aquariums.
People often ask me, "What filter do you use use in a botanical-style aquarium?" My answer is usually that it just doesn't matter. You can use any type of filter. The reality is that, if allowed to evolve and grow unfettered, the aquarium itself- all of it- becomes the "filter."
You can embrace this philosophy regardless of the type of filter that you employ.
My sumps and integrated filter compartments in my A.I.O. tanks are essentially empty.
I may occasionally employ some activated carbon in small amounts, or throw some "Shade" sachets in there if I am feeling it- but that's it. The way I see it- these areas, in a botanical-style aquarium, simply provide more water volume, more gas exchange; a place for bacterial attachment (surface area), and perhaps an area for botanical debris to settle out. Maybe I'll remove them, if only to prevent them from slowing down the flow rate of my return pumps.
But that's it.
A lot of people are initially surprised by this. However, when you look at it in the broader context of botanical style aquariums as miniature ecosystems, it all really makes sense, doesn't it? The work of these microorganisms and other life forms takes place throughout the aquarium.
I admit, there was a time when I was really fanatical about making sure every single bit of detritus and fish poop and all that stuff was out of my tanks. About undetectable nitrate. I was especially like that in my earlier days of reef keeping, when it was thought that cleanliness was the shit!
It wasn't until years into my reef keeping work, and especially in my coral propagation work, that I begin to understand the value of food, and the role the it plays in aquatic ecosystems as a whole. And that "food" means different things to different aquatic organisms. The idea of scrubbing and removing every single trace of what we saw as "bad stuff" from our grow-out raceways essentially deprived the corals and supporting organisms of an important natural food source.
We'd fanatically skim and remove everything, only to find out that...our corals didn't look all that good. We'd compensate by feeding more heavily, only to continue to remove any traces of dissolved organics from the water...
It was a constant struggle- the metaphorical "hamster wheel"- between keeping things "clinically clean" and feeding our animals. We were super proud of our spotless water. We had a big screen when you came into our facility showing the parameters in each raceway. Which begged the question: Were we interested in creating sterile water, or growing corals?
Eventually, it got through my thick skull that aquariums- just like the wild habitats they represent-are not spotless environments, and that they depend on multiple inputs of food, to feed the biome at all levels. This meant that scrubbing the living shit (literally) out of our aquariums was denying the very biotia which comprised our aquariums their most basic needs.
That little "unlock" changed everything for me.
Suddenly, it all made sense.
This has carried over into the botanical-style aquarium concept: It's a system that literally relies on the biological material present in the system to facilitate food production, nutrient assimilation, and reproduction of life forms at various trophic levels.
It's 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 asshole on Instagram with the flashy, gadget-driven tank. It's not always fun at first for some, and it initially seems like you're somehow doing things wrong.
It's about faith. Faith in Mother Nature, who's been doing this stuff for eons.
It's about nuance.
It's about looking at things a bit different that we've been "programmed" to do in the aquarium hobby for so long. It's about not being afraid to question the reasons why we do things a certain way in the hobby, and to seek ways to evolve and change practices for the benefits of our fishes.
It takes time to grasp this stuff. However, as with so many things that we talk about here, it's not revolutionary...it's simply an evolution in thinking about how we conceive, set up, and manage our aquariums.
Sure, the aquairum is a "filter" of sorts, if you want to label it as such. However, it's so much more: A small, evolving ecosystem, relying on natural processes to bring it to life.
Wrap you head around that.
It might just change everything in the hobby for you.
Stay open-minded. Stay thoughtful. Stay bold. Stay curious. Stay diligent. Stay observant...
And Stay Wet.
As you know, we receive a lot of questions around here about all sorts of aquarium-related topics. Usually, my answer is directly to the individual who asked, in the form of an email or DM. Sometimes, however, the answer is such that it is best addressed in the form of a blog post!
Recently, a hobbyist asked me what my opinion was of the botanical-style aquarium as a type of "aquascaping approach", and how it fits in the overall aquascaping "universe." Exactly what our "thing" is...
First, I start with my assertion that the botanical-style aquarium is NOT an aquascaping "style"- it's a methodology to create a more natural-functioning aquarium by utilizing botanical materials to "fuel" the process. The look is a "collateral benefit" of the methodology.
I admit, I've never really been much of an "aquascaper."
You know- those hobbyists who can take a few rocks and a piece or two of wood and turn them into some sort of amazing design. That takes amazing talent and vision. And I made peace with that decades ago! I greatly admire those true artists who can employ all sorts of technique, color-coordination, and ratio and such snd come up with some incredible stuff with seeming ease.
On the other hand, I look at a lot of aquascaping work, admire the effort and talent and such, and then get this feeling in my gut that I can't always explain. Well, I can, but it's not always...nice. Like, I look at many "modern scapes" and just kind of...yawn.
Ouch, I'm sounding like a proper asshole, I know.
But seriously, it's not that I think their work is shitty or something...I just find the "styles" of many of the beautiful tanks out there which the world goes crazy over to be just a bit..boring. Or, should I say- not my taste. Yeah, that's better.
It's weird, I do like certain planted tanks that just blow me away. Our friend, George Farmer, does amazing planted 'scapes which I would happily have in my own home if I had the talent. I love the work of our own Johnny Ciotti- a guy who was trained as a classic "Nature Aquarium Style" 'scaper, yet, a true artist who can take botanical elements and create stunning botanical-style aquariums with ease. Jeff Sense of Aquarium Design Group is another person who can work with just about any "media" you give him- rocks, wood, plants- and crank out something that is unmistakingly original, dynamic, and gorgeous.
I'll never be as talented as those guys. And I'm perfectly okay with that. I'm comfortable in my own skin. And it's largely because, a long time ago, I found what I truly love, and work with that. I think we should all have that degree of comfort with what we love. Sadly, many hobbyists don't- and feel that-in order to be considered "talented" or whatever- that they have to embrace a certain style or technique.
I often think about the so-called "diorama style" tanks that pop up in contests, and are all over Instagram or whatever. They require enormous talent to execute, but they're far more "art" than they are "natural aquariums", I suppose. And I guess that's what gets me- these weird fantasy scapes have live plants and glued-together rock and wood and stuff, but they are anything but "natural", IMHO.
I guess what gets me is that the aquascaping world lauds these scapes as "the shit"- and sure, they are fantastic- amazing work. When they're called "natural", that sends shivers down my spine...I mean, doesn't Nature offer scenes that are equally as complex, interesting, and challenging to pull off? And, with the added bonus that you can replicate the function of these habitats, I can't see why you don't see more representations of flooded forests, vernal pools, Pantanal meadows, etc. in the major aquascaping contests.
I imagine how amazing a tank one of those diorama-style 'scapers could pull off if he/she tried to replicate an actual aquatic habitat as found in Nature. With there talent and ability to bring a vision to life....wow! I mean, sure, such a tank won't have a beach scene, winding road into a forest, or a mountain range, or any of that other cliche stuff- but it will have all of the amazing vibrancy and intricate structure of natural aquatic habitats. The possibilities are endless.
I've postulated about why we don't see more of these things in contests..
However, the benefits of entering tanks like this would be many, including calling attention to the wonders of the natural world, and the precious wild habitats which are often threatened by human activities.
I think that a good part of the reason is that these natural habitats aren't "tight" from a design standpoint. They don't -on the surface, at least-seem to require any "discipline" in order to replicate. You have to cede a certain amount of your work to Nature. I think that freaks out a lot of artistic aquascapers.
Nature, and Her many ecological niches and features, provides an endless array of habitats to recreate in the home aquarium. And my "POV" has always been to look at these niches, figure out how and why they formed, and why they look the way that they do. By researching the processes which helped create the habitat, I'm challenged to create an aquarium which attempts to replicate both the form and the function of it.
Some of these habitats are not what you'd expect to see in an aquairum. They look- and function- fundamentally different from what we've worked with before.
Some of the aesthetics of these wild habitats freaks people out. They look so...random...so...undisciplined, if we were to ascribe artistic terms to them. It's a world where we set up the system to allow Nature to do the "finishing" work. It require s a certain trust in natural processes, and the ability to let go. The ability to realize that what we see is a "finished product" is only the very beginning.
"The Delta at the intersection between science and art.”
That's where I play.
I like it here. A lot of you do, too.
This "not quite a biotope aquarium" and "not quite an artistic aquascape" thing is the perfect "sweet spot" for my interest, attention, and skills. And I think it's the place where I can be most useful to the hobby. Biotope-inspired, I suppose. A more forgiving, easygoing "style" which places function over aesthetics, yet somehow always leads to something that I find aesthetically pleasing.
It's a strange, yet wonderful place, where I've made the many "mental shifts" that allow me to enjoy the beauty and elegance of stuff like decomposing leaves, sediment, biofilms, fungal growths, random aggregations of leaves, etc. A place where much of the attraction is because the aquariums I create are intended to let Nature do some of the work.
If I were forced (and yeah, "forced" is the right word, because there are no defining "rules" here...no way) to offer some defining characteristics of the "botanical-style" aquarium, I'd say that a certain "randomness", actually, is it.
I mean, we're all about replicating what happens in Nature, NOT about perfectly proportioned placements and such. Now, I must admit, some of the world-class aquascapers that have worked with our botanicals have applied these concepts to these types of aquariums and have produced stunning results.
However, I think the "raw" botanical aquarium "essence" is about a certain degree of randomness.
I believe that an aquarium that attempts to replicate a scene like the ones we're talking about starts with what looks like really artificial placement of wood, anchored by numerous details which soften, define, and fill in the scape. A sort of analog to the theater/motion picture concept of "mise en scene", where pieces literally set the stage and help tell a story by providing context.
Yes, unlike a scape which depends upon growth of plants to fill it in and "evolve" it, the botanical-style blackwater/brackish aquarium is largely hardscape materials, which requires the adept placement of said materials to help fill in the scene. And of course, part of the "evolution" is the softening, redistribution, and break down of botanical materials over time...just like what happens in nature.
I suppose this little rant could be viewed as a "defense" our "style", which on occasion has been criticized as "sloppy", "lazy", "undisciplined", etc...😆
Perhaps it is to some. However, I think it serves to re-examine what I feel is one of the foundational philosophies of the botanical-style aquarium "aesthetic."
I must confess, it's an aesthetic which certainly doesn't appeal to everyone. In fact, many in the mainstream aquascaping world tended to levy all sorts of "constructive criticisms" and "Yeah, but..." comments about our practices and ideas for a while...Less these days, BTW!
And that is part of the attraction of this the of aquarium for me. Rather than conform thoroughly to some sort of "rules" based on design, layout, and technique, this type of aquarium tends to ask for very basic initial design, and lets Mother Nature handle a lot of the emerging details over time.
I think that there is a certain hunger for something different in the hobby right now. I feel that we've dedicated most of this century to figuring out ways to push back against Nature's processes. We've spent a tremendous amount of time looking for ways to remove things that we don't feel belong in our tanks: Algae, biofilms, decomposition, etc. Stuff that we, as a hobby, feel to be unwelcome, unattractive, and even "detrimental."
And quite honestly, I think we see these things as undesirable or "unsafe" because they are artifacts of outdated thinking...holdovers from a time when we felt that our technology gave us the edge to accomplish what Nature couldn't.
And of course, the reality is that the technology can accomplish some of these things, like nutrient export, heat control, circulation, etc.-but what really powers the miniature ecosystems which our aquariums actually are- is the microbiome: Fungal growths, bacterial biofilms, the process of decomposition, etc. Stuff which looks distasteful to many, yet stuff that is fundamental to the function-and yeah, the look- of our tanks.
It's not just a look. Not just an aesthetic. Not just a mindset...
It's a way to incorporate natural materials to achieve new and progressive results with the fishes and plants we've come to love so much.
And, It's still early days.
A ground floor opportunity for every aquarist who gives this stuff a shot to make a meaningful- and beautiful contribution to the evolving state of the art of the botanical-style aquarium., and to share what Nature really looks like with people all over the world.
I'm fascinated by the "mental adjustments" that we need to make to accept the aesthetic and the processes of natural decay, fungal growth, the appearance of biofilms, and how these affect what's occurring in the aquarium. It's all a complex synergy of life and aesthetic.
And we have to accept Nature's input here.
Nature dictates the speed by which this decomposition process occurs. We set the stage for it- but Nature is in full control. As an aquarist with a botanical-style aquarium, it's our "job" to observe and know when- or if- to intervene by adding or removing botanicals as they break down.
The great Takashi Amano's whole idea in a nutshell was to replicate Nature to a certain extent by accepting it and laying a conceptual groundwork for it to unfold. (Just look at all of the pics of grassy fields and moss-covered fenceposts in Amano's books. He got it. He felt something.) Now, granted, his general aesthetic involved plants and what seems to be a natural-looking aquascape, although executed in an intentionally artistic way.
There is nothing wrong with this. Some of the world's most beautiful aquariums were/are created this way.
However, what I noticed over time in the freshwater world was an almost obsessive, rigid adherence to certain parts of Amano's formula and aesthetic; specifically, ratios, placement of hardscape and plants, and a certain type of aesthetic formula that one had to replicate in order to gain legitimacy or "acceptance" from the community.
I really don't think it was Amano's intent.
"Wabi-sabi", the Japanese philosophy which embraces the ephemeral nature of the existence of things, was/is a key concept in Amano's approach, and it still is.
I think it's fallen into a bit of "disuse", though, in the "Nature Aquarium" movement, as aquarists aspired to replicate the style proffered in his works, perhaps trying to by-pass what seemed to be a less exciting -or less immediately rewarding- part of his approach.
I think that this is why we have some many "diorama-style" tanks in competitions, with "details" like twigs and roots glued to wood...and I also think it's why we see more and more serious aquascapers taking another look at a more realistic type of aquarium utilizing botanicals. Aquariums which embrace decay, detritus, biofilms, and a less "ratio-centric", more "random" natural look.
I think many aquascapers are simply tired of overly-stylized and are leaning back into a truly more natural look. And maybe...perhaps- they're starting to come around to the idea of "functional aesthetics', too!
A less rigidly aesthetically-controlled, less "high-concept" approach to setting the stage for...Nature- to do what she's done for eons without doing as much to "help it along." Rather, the mindset here is to allow nature to take it's course, and to embrace the breakdown of materials, the biofilms, the decay...and rejoice in the ever-changing aesthetic and functional aspects of a natural aquatic system- "warts and all" -and how they can positively affect our fishes.
Wabi-Sabi? Yeah, I think so. I think we embody the concept beautifully.
The initial skepticism and resistance to the idea of an aquarium filled with biofilms, decomposition, and tinted water has given way to enormous creativity and discovery. Our community has (rather easily, I might add!) accepted the idea that Nature will follow a certain "path"- parts of which are aesthetically different than anything we've allowed to occur in our tanks before- and rather than attempting to mitigate, edit, or thwart it, we're celebrating it!
I think this is where Tannin Aquatics falls, if you had to nail us down into one specific "stylistic/philosphical approach" to aquariums.
The "space between", so to speak. Sort of straddling multiple approaches, with Nature as the ultimate "critic."
This can take us to some really cool places.
Let's go there.
Stay creative. Stay excited. Stay bold. Stay thoughtful...
And Stay Wet.
One of the absolute "givens" in the aquarium hobby is the necessity of doing some stuff your self- figuring out and executing ways to fix things, set stuff up, accomplish all sorts of aquarium-related tasks, ranging from the most mundane to the highest-level practices, and everything in-between.
Now, there is a significant body of hobby knowledge about all sorts of stuff out there- I mean, we've been at this for a while now.
The aquarium hobby as we know it has really been around for about 100 plus years (Okay, nerd- I know that the Ancient Greeks and Chinese kept carp, or whatever-but we're talking about the "modern" aquarium hobby, okay? That's really like the last century.). During that time, lots of stuff has been figured out- the nitrogen cycle, many of the critical environmental needs of our fishes, husbandry practices, heater and filter technology, etc...
All well and good, but there is a lot of information out there- and a lot of ways to do things...And no real "central clearing house" for information, right? You have to dig for it sometimes You have to use your brain, ask around, utilize Google, read blogs and magazine articles, haunt forums, etc. And even then, you literally have to sort the B.S. and drivel from the real, useful information.
No one said this shit was easy...But it's not difficult, either.
Take for example, gadgets.
Unlike many of you, I am one of those aquarists who barely has the "Quasi-DIY Gene", and I know it. I can scheme out and plumb my reef aquarium, set up a canister filter, coordinate a flow pattern with off-the-shelf electronic pumps, dial in a CO2 regulator, etc. I can almost program a controller without throwing it at the wall, so I suppose that's progress. But that's the outer limits of my hobby mechanical skill set.
In the "serious" aquarium hobby, this is considered fairly basic stuff. However, when it comes to the hardcore stuff, like building a reliable and safe auto top off system, constructing a custom stand, or assembling my own LED lighting array, that's where I beg off and seek the guidance of fellow fish geeks that love that kind of stuff.
I know my limits.
Like most of you, I've acquired a fairly extensive set of rather obscure skills, like understanding the nuances of ball valves, re-starting a canister filter, culturing Daphnia, adjusting a CO2 solenoid, etc. These are skills you sort of accumulate by either observing other fish geeks, or just by jumping in and doing them.
And, occasionally you'll figure out how to get something like a calcium reactor or doser going on the first try, be it through luck or just having the skills required. However, if you're like most fish geeks, more often than not, you'll get it about 80% right the first try.
Just read the instructions...er, sort of...
Have you ever noticed that there is really no "instruction manual" for aquarium projects, or even for many of the pieces of equipment that we use? Okay, yeah, there are some famous You Tubers who do have videos on some of that kind of stuff...There are resources out there for almost everything. If you look really hard.
That's the key. Even in this hyper-searchable era, you still need to dig for stuff you want to find out more about. That's life. Decades ago, it was time to go to the library, go to a fish club meeting, or hang out at the LFS and pick the brains of some hardcore hobbyists. Those things still work, btw.
We as a group are pretty damn impatient, though! I will literally have times when I share a link on Instagram or Facebook to an article I wrote on a specific topic, like, preparing botanicals or whatever- and in the comments on the post, someone will inevitably ask, "Cool! How do you prepare those things before you add them to your tank? Do you have to boil them?"
Like, WTF? JUST CLICK ON THE FUCKING LINK!
I mean, it gets me sort of cranky. Like, how lazy are we?
I suppose, in all fairness, it's the desire to obtain more exact, more concise, or more immediate information that results in these bizarrely annoying questions. Like, "Just cut to the chase. How long do I have to boil my Cariniana pods for?"
That's why infographics exist, right?
Ok, you get my drift.
I mean, why should they? There are so many variations on how to do stuff, what exact components to use, and how long it takes (ie; how difficult it is) that anything more than generalities about many topics is not only hard to share- it's likely irresponsible.
Yeah, you kind of need to research what you can, roll up your sleeves, take a deep breath, and just go for it. Or, you can pay someone to do it for you, right? There are many great aquarium service people out there who do just that!
Many aquarium products do come with a diagram, maybe some basic introductory stuff about why it's good to have the piece of equipment (C'mon, you KNOW that already, or you wouldn't have purchased it, right? You STILL need to be sold on why a calcium reactor is a good thing for your reef aquarium after you bought it? That sort of stuff always makes me laugh), and if you're lucky, a decent set of instructions- or an exploded diagram.
Yeah, I agree- in some instances with some products, the manufacturers would be far better off providing a very detailed assembly and placement information for the purchaser, IMHO. Oh, sure, there are many manufacturers who do this, but not all. I know, it sometimes seems like it's "expected" that, as a fish geek, you have this "hidden knowledge database" programmed in your head to figure out how to assemble everything.
And in some ways, a lot of it makes sense. One of my buddies takes the hard stance that, if you can't figure out how to set up a piece of gear you purchased, you're probably not ready for it.
Hard to argue with that, right?
Again, we need to educate ourselves as hobbyists. If you're into this game, you'll WANT to research and learn, right? You're not just getting some gadget "because they say to do it!" -right? If you are, you need to re-think it.
Yeah, skills and experiences do go hand in hand. You sometimes DO need to do stuff to understand it...However, what you don't have "programmed", you can always find by tapping into the "matrix" (sorry, had to borrow the term) of hobby knowledge that is "out there." Have you noticed that? Often times, you must acquire the arcane knowledge that you need by internet search, listening to podcasts, watching You Tube, haunting the LFS, or hanging with your fish-keeping buddies and visiting their setups?
Fun, yes, but often frustrating for some.
There is really no formal "aquarium construction guide" out there. None. Yes, lots of books talk about the theoretical and broad implementation of this gadget or another, but no one has really written a treatise with turnkey information about how to construct a perfect aquarium.
Not really. There is no ONE perfect way.
We all know this- regardless of if we want to admit it or not. And yeah, some stuff you just need to "work through", understand the rationale for, and go for it. You need to learn for yourself. And you DO know by now that having a collection of the best and most expensive trendy gadgets and stuff won't make you a better aquarist. You need to understand the basics of the hobby. I've seen plenty of tanks quipped with the best and baddest of everything which positively sucked.
You know this, however.
Now, I suppose, if you have the DIY thing in your game, you hate this state of affairs, and you can write a bit, there's your calling- write a book on how to equip a modern aquarium system, with detailed diagrams and step-by-step instructions on how to assemble it. Woah! That would upset the entire balance of the universe, because suddenly, hobbyists would have a single resource to turn to for reference on how to do_______! You'd no longer have to go though painful trial and error while building what you feel is a properly-equipped aquarium!
Oh sure, there are some of you who would scoff at the idea, saying that the painful accumulation of this knowledge and the skills to pull of these projects SHOULD be gained through blood, sweat, and tears- you've gotta "pay your dues" by searching for obscure information and failing a few times on the way.
I mean, I understand that. In the end, it makes you a better hobbyist- assuming you don't quit along the way. Don't quit.
And I suppose, one could make an argument for having everything concisely presented on every possible aquarium topic, right? I mean, how would you feel the next time you fly from say, LA to New York, if the two guys up front were "paying their dues" during YOUR flight? Or, if the guy in the surgical scrubs patting your arm as you fall asleep on the operating table is "figuring out your procedure as he goes?"
Yeah, not so good, huh?
Okay, those are a bit extreme.
The answer is likely somewhere in between.
We need to learn most things by learning, studying, researching, and executing. You can always ask questions of a more advanced or experienced hobbyist if you're stuck. However, don't always take the easy way out and just ask for the entire answer for a topic that's widely discussed everywhere, and then get all bummed out because no one is giving you every single concise answer.
Don't be lazy. Do some of the work yourself. Avail yourself to the tons of hobby resources out there. But don't expect that the exact answer to your exact question is always easy to find. You need to dig. You might just learn more than you expected to!
Yes, we all get a bit frustrated looking for answers.
Like, I get it. I can't be totally without compassion on this topic!
Sometimes, we are excited and perhaps a bit overwhelmed at the apparent complexity of a new subject, but we're eager to learn. We just need a push in the right direction. I get that, and that's why, in our area of expertise, I'm always here to help. You'll find that most hobbyists and industry people will do the same....TO a point. And I encourage you to make use of such hobby resources when necessary.
However, for a small but noticeable sliver of the aquarium hobbyist population, there is this "thing" about taking even the slightest initiative to do some research.
"C'mon Scott, it's hard. There's so much stuff out there. Besides, you understand this stuff. And I didn't grow up doing this..."
That's literally a "mashup" of some of the "feedback" I've received from people who asked tons of questions for which the answers were readily available. It makes me scratch my head.
I mean, Google, for example, is one of the greatest resources we've ever had as a species. It's so easy to use and so powerful that it can literally make one wonder if the library as we know it is simply a relic of a gentler, kinder era, perhaps having outlived some of it's usefulness as a "go-to" resource for knowledge (It hasn't IMHO, but you could argue that it has diminished just a bit in value for some...). To not use it is almost absurd in today's era.
Laziness is a shitty trait, IMHO. Don;'t be lazy. You're supposed to enjoy a hobby, right? You should WANT to do some research!
The scariest things are when someone who appears to be operating in a more "advanced" area of the hobby asks a question about something frighteningly basic, like pH, water exchanges, the value of quarantining new fishes, etc. Stuff that's "Aquarium Keeping 101." Like, ask yourself-why are you in the deep end of the pool if you can't even float?
You can do this. You can learn the fundamentals of the hobby, build upon them, and progress to more complex stuff. It's a matter of putting in some time and work. It doesn't have to be drudgery.
Sure, people are there to help along the way. Resources are available...Yet you can't expect a grand "Aquarium Instruction Manual" with answers to 400,000 possible obscure questions on every single aspect of the hobby to just appear for you (Not yet, anyways...perhaps some day!).
And that's okay. The acquisition of knowledge in the hobby is a journey to be enjoyed and savored- not reviled and loathed. Just take a deep breath, and read beyond the cute pic in that Instagram post...Dig to page 3 of a Google search if you haven't found the answer you're looking for just yet. It's there.
And of course- always share what you know when you do figure it all out. Add to the body of knowledge in the hobby.
Just read the instructions...sort of-before you jump. It kind of works. Really!
So, I say to you: Search for knowledge. Ask questions. Execute. Learn from the experience. Share said acquired knowledge. Complain more, if you want, but you might actually find that you'll complain less when you just try stuff.
Stay courageous. Stay diligent. Stay curious. Stay studious. Stay persistent...
And Stay Wet.
A couple of days back, I was chatting with a fellow hobbyist who wanted to jump in to something a bit different within the aquarium hobby, but was afraid of the possible consequences-both socially and in his aquariums. He feared criticism from "them", and that just froze him. I felt bad that he was so afraid of criticism from others should he question the "status quo" within the hobby.
Perhaps my story might be helpful to you if you're afraid of such criticisms.
For generations, we've been told in the aquarium hobby that we need to be concerned about the appearance of all kinds of stuff in our tanks, like algae, detritus, and "biocover".
For some strange reason, we as a hobby group seems emphasize stuff like understanding some biological processes, like the nitrogen cycle, yet we've also been told to devote a lot of resources to siphoning, polishing, and scrubbing our tanks to near sterility.
It's a strange dichotomy.
I remember the first few botanical-style tanks I created, almost two decades ago now, would hit that phase early on when biofilms and fungal growths began to appear, and I'd hear my friends telling me, "Yeah, your tank is going to turn into a big pile of shit. Told you that you can't put that stuff in there."
Because that's what they've been told. The prevailing mindset in the hobby was that the appearance of these organisms was an indication of an unsuitable aquarium environment.
Anyone who's studied basic ecology and biology understands that the complete opposite is true. The appearance of these valuable life forms is an indicator that your aquatic environment is ideal to foster a healthy, diverse community of aquatic organisms, including fishes!
Exactly like in Nature.
I remember telling myself that this is what I knew was going to happen. I knew how biofilms and fungal growths appear on "undefended" surfaces, and that they are essentially harmless life forms, exploiting a favorable environment. I knew that fungi appear as they help break down leaves and botanicals. I knew that these are perfectly natural occurrences, and that they typically are transitory and self-limiting to some extent.
Normal for this type of aquarium approach. I knew that they would go away, but I also knew that there would be a period of time when the tank might look like a big pool of slimy shit. Or, rather, it'd look like a pile of slimy shit to those who weren't familiar with these life forms, how they grow, and how the natural aquatic habitats we love so much actually function and appear!
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 leaf litter zones and how productive and unique they were.
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.
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.
I knew that this type of aquatic habitat could be replicated in the aquarium successfully. I realized that it would take understanding, trial and error, and acceptance that the aquariums I created would look fundamentally different than anything I had experienced before.
I knew I might face criticism, scrutiny, and even downright condemnation from some quarters for daring to do something different, and then for labeling what most found totally distasteful, or have been conditioned by "the hobby" for generations to fear, as simply "a routine part of the process."
It's what happens when you venture out into areas of the hobby which are a bit untested. Areas which embrace ideas, aesthetics, practices, and occurrences which have existed far out of the mainstream consciousness of the hobby for so long. Fears develop, naysayers emerge, and warnings are given.
Yet, all of this stuff- ALL of it- is completely normal, well understood and documented by science, and in reality, comprises the aquatic habitats which are so successful and beneficial for fishes in both Nature and the aquarium. We as a hobby have made scant little effort over the years to understand it. And once you commit yourself to studying, understanding, and embracing life on all levels, the world of natural, botanical-style aquariums and its untapped potential opens upon to you.
Mental shifts are required. Along with study, patience, time, and a willingness to look beyond hobby forums, aquarium literature, and aquascaping contests for information. A desire to roll up your sleeves, get in there, ignore the naysayers, and just DO.
Don't be afraid of things because they look different, or somehow contrary to what you've heard or been told by others is "not healthy" or somehow "dangerous." Now sure, you can't obey natural "laws" like the nitrogen cycle, understanding pH, etc.
You can, however, question things you've been told to avoid based on superficial explanations based upon aesthetics.
Stuff that makes you want to understand how life forms such as fungi, for example, arise, multiply, snd contribute to the biome of your aquarium.
Let's think about fungi for a minute...a "poster child" for the new way of embracing Nature as it is.
Fungi reproduce by releasing tiny spores that then germinate on new and hospitable surfaces (ie, pretty much anywhere they damn well please!). These aquatic fungi are involved in the decay of wood and leafy material. And of course, when you submerge terrestrial materials in water, growths of fungi tend to arise. Anyone who's ever "cured" a piece of wood for your aquarium can attest to this!
Fungi tend to colonize wood because it offers 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 these materials! 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?
And of course, fishes and invertebrates which live amongst and feed directly upon the fungi and decomposing leaves and botanicals contribute to the breakdown of these materials as well! Aquatic fungi can break down the leaf matrix and make the energy available to feeding animals in these habitats. And look at this little gem I found in my research:
"There is evidence that detritivores selectively feed on conditioned leaves, i.e. those previously colonized by fungi (Suberkropp, 1992; Graca, 1993). Fungi can alter the food quality and palatability of leaf detritus, aecting shredder growth rates. Animals that feed on a diet rich in fungi have higher growth rates and fecundity than those fed on poorly colonized leaves. Some shredders prefer to feed on leaves that are colonized by fungi, whereas others consume fungal mycelium selectively..."
"Conditioned" leaves, in this context, are those which have been previously colonized by fungi! They make the energy within the leaves and botanicals more available to higher organisms like fishes and invertebrates!
The aquatic fungi which will typically decompose leaf litter and wood are the group known as “aquatic hyphomycetes”. Another group of specialists, "aero-aquatic hyphomycetes," colonize submerged plant detritus in stagnant and slow- flowing waters, like shallow ponds, puddles, and flooded forest areas. Fungal communities differ between various environments, such as streams, shallow lakes and wetlands, deep lakes, and other habitats such as salt lakes and estuaries.
And we see them in our own tanks all the time, don't we? Sure, it's easy to get scared by this stuff...and surprisingly, it's even easier to exploit it as a food source for your animals! We just have to make that mental shift... As the expression goes, "when life gives you lemons, make lemonade!"
I knew when I started Tannin that I had to "walk the walk." I had to explain by showing my tanks, my work, and giving fellow hobbyists the information, advice, and support they needed in order to confidently set out on their own foray into this interesting hobby path.
I'm no hero. Not trying to portray myself as a visionary.
The point of sharing my personal experience is to show you that trying new stuff in the hobby does carry risk, fear, and challenge, but that you can and will persevere if you believe. If you push through. IF you don't fear setbacks, issues, criticisms from naysayers.
You have to try. In my case, the the idea of throwing various botanical items into aquariums is not my invention. It's not a totally new thing. People have done what I've done before. Maybe not as obsessively or thoroughly presented (and maybe they haven't built a business around the idea!), but it's been done many, many times.
The fact is, we can and should all take these kinds of journeys.
Stay the course. Don't be afraid. Open your mind. Study what is happening. Draw parallels to the natural aquatic ecosystems of the world. Look at this "evolution" process with wonder, awe, and courage.
And know that the pile of decomposing leaves, fungal growth, and detritus that you're looking at now is just a steppingstone on the journey to an aquarium which embrace nature in every conceivable way.
Stay brave. Stay curious. Stay diligent. Stay observant...
And Stay Wet.
