The Tint

The slow(er) road to success with fish stocking...

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.” 

Why?

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.

Letting go...

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.

Nope.

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.

Don't laugh:

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.

Yeah.

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. 

Weird, huh?

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?

Maybe.

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.

 

It's only a "fail" if you make it one...

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!”

Really.

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?

Yeah. 

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.

Enough said.

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.

Discuss them.

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.

Trust me.

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?

Right!

Stay bold. Stay thoughtful. Stay honest. Stay curious. Stay experimental...

And Stay Wet.

The Botanical-Style Aquarium: A "filter" of its own, and other biological musings...

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?

Let's summarize:

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.

Yeah, detritus.

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.

Just:

Don't overstock.

Don't overfeed.

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.

Cool Places.

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.

That's absurd.

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.

What our fishes eat...The wonder of food webs.

Yes, I admit that we talk about some rather obscure topics around here. Yet, many of these topics are actually pretty well known, and even well-understood by science. We just haven't consciously applied them to our aquarium work...yet.

One of the topics that we talk about a lot are food webs. To me, these are fascinating, fundamental constructs which can truly have important influence on our aquariums.

So, what exactly is a food web?

 

A food web is defined by aquatic ecologists as a series of "trophic connections" (ie; feeding and nutritional resources in a given habitat) among various species in an aquatic community. 

All food chains and webs have at least two or three of these trophic levels. Generally, there are a maximum of four trophic levels. Many consumers feed at more than one trophic level.

So, a trophic level in our case would go something like this: Leaf litter, bacteria/fungal growth, crustaceans...

In the wild aquatic habitats we love so much, food webs are vital to the organisms which live in them. They are an absolute model for ecological interdependencies and processes which encompass the relationship between the terrestrial and aquatic environments.

In many of the blackwater aquatic habitats that we're so obsessed with around here, like the Rio Negro, for example, studies by ecologists have determined that the main sources of autotrophic sources are the igapo, along with aquatic vegetation and various types of algae. (For reference, autotrophs are defined as organisms that produce complex organic compounds using carbon from simple substances, such as CO2, and using energy from light (photosynthesis) or inorganic chemical reactions.)

Hmm. examples would be phytoplankton!

Now, I was under the impression that phytoplankton was rather scarce in blackwater habitats. However, this indicates to scientists is that phytoplankton in blackwater trophic food webs might be more important than originally thought! 

Now, lets get back to algae and macrophytes for a minute. Most of these life forms enter into food webs in the region in the form of...wait for it...detritus! Yup, both fine and course particular organic matter are a main source of these materials. I suppose this explains why heavy accumulations of detritus and algal growth in aquaria go hand in hand, right? Detritus is "fuel" for life forms of many kinds.

Food production- supplementary or otherwise- is something that not only is possible in our tanks; it's inevitable.

I firmly believe that the idea of embracing the construction (or nurturing) of a "food web" within our aquariums goes hand-in-hand with the concept of the botanical-style aquarium. With the abundance of leaves and other botanical materials to "fuel" the fungal and microbial growth readily available, and the attentive husbandry and intellectual curiosity of the typical "tinter", the practical execution of such a concept is not too difficult to create.

We are truly positioned well to explore and further develop the concept of a "food web" in our own systems, and the potential benefits are enticing! 

Work the web- in your own aquarium!

Stay curious. Stay observant. Stay creative. Stay diligent. Stay open-minded...

And Stay Wet.

Just read the instructions...sort of.

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.

Not bad.

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?

Books will talk in sweeping generalities about stuff like the need for a multistage canister filter in an Mbuna tank, or a kalk stirrer or reactor for a reef, and maybe even have a computer-generated diagram showing where it is in the setup scheme. However, you never see things like, "In order to make the reactor work, you'll need a ______ pump, two feet of 1/2" vinyl tubing, two ball valves, and enough room in your equipment area to accomodate a 4" x 20" reactor body. The assembled unit should be placed approximately 4 inches to the side of the sump, with enough clearance to____________."

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. 

Weird, huh?

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.

Win-win.

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.

Transitional Habitats...A new aquarium hobby frontier?

We've spent a lot of time over the least several years talking about the idea of recreating specialized aquatic systems. We've talked a lot about transitional habitats- ecosystems which alternate between terrestrial and aquatic at various times of the year.  These are compelling ecosystems which push the very limits of conventional aquarium practice. 

As you know, we take a "function first" approach, in which the aesthetics become a "collateral benefit" of the function. Perhaps the best way to replicate these natural aquatic systems inner aquariums is to replicate the factors which facilitate their function. So, for example, let's look at our fave habitats, the flooded forests of Amazonia or the grasslands of The Pantanal.

To create a system that truly embraces this idea in both form and function, you'd start the system as a terrestrial habitat. In other words, rather than setting up an "aquarium" habitat right from the start, you'd be setting up what amounts to a terrarium. Soil/sand, terrestrial plants and grasses, leaves, seed pods, and "fallen trees/branches" on the "forest floor."

 

You'd run this system as a terrestrial display for some extended period of time- perhaps several weeks or even months, if you can handle it- and then you'd "flood" the terrestrial habitat, turning it into an aquatic one. Now, I'm not talking about one of our "Urban Igapo" nano-sized tanks here- I"m talking about a full-sized aquarium this time.  

This is different in both scale and dynamic. After the "inundation", it's likely that many of the plants and grasses will either go dormant or simply die, adding other nutrient load in the aquarium.

A microbiome of organisms which can live in the aquatic environment needs to arise to process the high level of nutrients in the aquarium. Some terrestrial organisms (perhaps you were keeping frogs?) need to be removed and re-housed.

The very process of creating and populating the system during this transitional phase from terrestrial to aquatic is a complex, fascinating, and not entirely well-understood one, at least in the aquarium hobby. In fact, it's essentially a virtually unknown one. We simply haven't created all that many systems which evolve from terrestrial to aquatic.

Sure, we've created terrariums, paludariums, etc. We've seen plenty of "seasonally flooded forest" aquairums in biotope aquarium contests...But this is different. Rather than capturing a "moment in time", recreating the aquatic environment after the inundation, we're talking about recreating the process of transformation from one habitat to another.

Literally, creating the aquatic environment from a terrestrial one.

Psychologically, it would be sort of  challenging!

I mean, in this instance, you've been essentially running a "garden" for several months, enjoying it and meeting the challenges which arise, only to embark several months later on a process which essentially destroys what you've created, forcing you to start anew with an entirely different environment, and contend with all of its associated challenges (the nitrogen cycle, nutrient control, etc.)

Modeling the process. 

Personally, I find this type of approach irresistible. Not only do you get to enjoy all sorts of different aspects of Nature- you get to learn some new stuff, acquire new skills, and make observations on processes that, although common in Nature, were previously unrecorded in the aquarium hobby. 

 

You'll draw on all of your aquarium-related skills to manage this transformation. You'll deal with a  completely different aesthetic- I mean, flooding an established, planted terrestrial habitat filled with soils and plants will create a turbid, no doubt chaotic-looking aquascape, at least initially. 

 

This is absolutely analogous to what we see in Nature, by the way.Seasonal transformations are hardly neat and tidy affairs. 

Yes, we place function over form. However, that doesn't mean that you can't make it pretty! One key to making this interesting from an aesthetic perspective is to create a hardscape of wood, rocks, seed pods, etc. during the terrestrial phase that will please you when it’s submerged.

You'll need to observe very carefully. You'll need to be tolerant of stuff like turbidity, biofilms, algae, decomposition- many of the "skills"we've developed as botanical-style aquarists.You need to accept that what you're seeing in front of you today will not be the way it will look in 4 months, or even 4 weeks.

You'll need incredible patience, along with flexibility and an "even keel.”

We have a lot of the "chops" we'll need for this approach already! They simply need to be applied and coupled with an eagerness to try something new, and to help pioneer and create the “methodology”, and with the understanding that things may not always go exactly like we expect they should.

For me, this would likely be a "one way trip", going from terrestrial to aquatic. Of course, much like we've done with our "Urban Igapo" approach, this could be a terrestrial==>aquatic==>terrestrial "round trip" if you want! That's the beauty of this. You could do a complete 365 day dynamic, matching the actual wet season/dry season cycles of the habitat you're modeling.

Absolutely. 

The beauty is that, even within our approach to "transformational biotope-inspired" functional ecosystems, you CAN take some "artistic liberties" and do YOU. I mean, at the end of the day, it's a hobby, not a PhD thesis project, right?

Yeah. Plenty of room for creativity, even when pushing the state of the art of the hobby! Plenty of ways to interpret what we see in these unique ecosystems.

Habitats which transition from terrestrial to aquatic require us to consider the entire relationship between land and water- something that we have paid scant little attention to in the aquarium hobby, IMHO. 

And this is unfortunate, because the relationships and interdependencies between aquatic habitats and their terrestrial surroundings are fundamental to our understanding of how they evolve and function.

There are so many other ecosystems which can be modeled with this approach! Floodplain lakes, streams, swamps, mud holes...I could go on and on and on. The inspiration for progressive aquariums is only limited to the many hundreds of thousands of examples which Nature Herself has created all over the planet.

We should look at nature for all of the little details it offers. We should question why things look the way they do, and postulate on what processes led to a habitat looking and functioning the way it does- and why/how fishes came to inhabit it and thrive within it.

With more and more attention being paid the overall environments from which our fishes come-not just the water, but the surrounding areas of the habitat, we as hobbyists will be able to call even more attention to the need to learn about and protect them when we create aquariums based on more specific habitats.

The old adage about "we protect what we love" is definitely true here!

And the transitional aquatic habitats are a terrific "entry point"into this exciting new area of aquarium hobby work.

Stay inspired. Stay creative. Stay observant. Stay resourceful. Stay diligent...

And Stay Wet.

No expiration date.

We talk a lot about starting up and managing botanical-style aquariums. We have had numerous discussions about set up and the accompanying expectations of the early days in the life of the little ecosystems we've created. However, what about the long term..The really long term? 

Like, how long can you maintain one of these aquariums? 

Do they have an "expiration date? A point when the system no longer "grows" or thrives? 

 

There is a term, sometimes used to describe the state of very old aquariums- "senescence." The definition is: "...the condition or process of deterioration with age." Well, that doesn't sound all that unusual, right? I mean, stuff ages, gets old, stops functioning well, and eventually expires...aquariums are no different, right?

Well, I don't think so.

Sometimes, this deterioration is referred to in the hobby by the charming name of "Old Tank Syndrome"

Now, on the surface, this makes some sense, right? I mean, if your tank has been set up for several years, environmental conditions will change over time. Among the many phenomenon brought up by proponents of this theory is the increase in nitrate levels. People who buy into "OTS" will tell you that nitrate levels will increase over time.

They'll tell you that phosphate, which typically comes into our tanks with food, will accumulate, resulting in excessive, perhaps rampant, algal growths. You know, the kind from which aquarium horror stories are made. 

They will tell you that the pH of the aquarium will decline as a result of accumulating nitrate, with hydrogen ions utilizing all available buffers, resulting in a reduction of the pH below 6 (like, IS that a problem?), which supposedly results in the beneficial bacteria ceasing to convert ammonia into nitrite and nitrate and creating a buildup of toxic ammonia... 

 

I mean, it's absolutely possible. We've talked about the potential cessation of the nitrogen cycle as we know it at low pH levels, and about the archaens which take over at these  low pH levels.  (That's a different "thing", though, and off topic ATM)

Of course, all of the bad things espoused by the OTS theorists can and will happen...If you never do any tank maintenance. If you simply abandon the idea of water exchanges, continue stocking and feeding your aquarium recklessly, and essentially abandon the basic tenants of aquarium husbandry.

The problem with this theory is that it assumes all aquarists are knuckleheads, refusing to perform water exchanges, while merrily going about their business of watching the pretty fishes swim. It seems to forecast some sort of inevitability that this will happen to every tank.

No way. Uh-uh. I call B.S. on this.

As someone who has kept all sorts of tanks (reef tanks, freshwater fish-only tanks, etc.) in operation for many years (my longest was 13 years, and botanical-style tanks going on 5 plus years), I can't buy into this idea. I mean, sure, if you don't set up a system properly in the first place, and then simply become lackadaisical about husbandry, of course your tank can decline.

But, here's the thing: It's not inevitable.

RULE OF THUMB: Do fucking maintenance, feed carefully, and don't overstock. This is not "rocket science!"

Rather than "Old Tank Syndrome"- a name which seems to imply that it's not our fault, and that it's like some unfortunate, random occurrence which befalls the unsuspecting-we should call it LAAP- "Lazy Ass Aquarists' Payback."

'Cause that's what it IS.  It's entirely the fault of a lazy-ass aquarist. Preventable and avoidable. 

Need more convincing that it's not some random "malady" that can strike any tank? That it's some "universal constant" which commonly occurs in all aquariums?

Think about the wild habitats which we attempt to model our aquariums after. Do these habitats decline over time for no reason? Generally, no. They will respond to environmental changes, like drought, pollution, sedimentation, etc. They will react to these environmental pressures or insults. They will evolve over time.

Now, sure, seasonal desiccation and such result in radical environmental shifts in the the aquatic environment and a definite "expiration date"- but you seldom hear of aquatic habitats declining and disappearing or becoming otherwise uninhabitable to fishes without some significant (often human-imposed) external pressures- like pollution, ash from fires or volcanoes, deliberate diversion or draining of the water source (think "Rio Xingu"), logging operations, climate change, etc.

Of course, our aquariums are closed ecosystems. However, the same natural laws which govern the nitrogen cycle or other aspects of the system's ecology in Nature apply to our aquariums. The big difference is that our tanks are almost completely dependent upon us as aquarists applying techniques which replicate some of the factors and processes which apply in Nature. Stuff like water exchanges, etc.

So if we keep up the nutrient export processes, don't radically overstock our systems, feed appropriately, maintain filters, and observe them over time, there is no reason why we couldn't maintain our aquariums indefinitely.

There is no "expiration date."

And the cool thing about botanical-style aquariums is that part of our very "technique" from day one is to facilitate the growth and reproduction of beneficial microfauna, like bacteria, fungal growths, etc., and to allow decomposition to occur to provide them feeding opportunities.What this does is help create a microbiome of organisms which, as we've said repeatedly, form the basis of the "operating system" of our tanks.

Each one of these life forms supporting, to some extent, those above...including our fishes.

So, yeah- botanical-style aquariums are "built" for the long run. Provided that we do our fair share of the work to support their ecology. Just because we add a lot of botanical material, allow decomposition, and tend to look on the resulting detritus favorably doesn't mean that these are "set-and-forget" systems, any more than it means they're particularly susceptible to all of the problems we discussed previously.

Common sense husbandry and observation are huge components of the botanical-style aquarium "equation."

As part of our regular husbandry routine, we keep the ecosystem "stocked" with fresh botanicals and leaves on a continuous basis, to replenish those which break down via decomposition. This is perfectly analogous to the processes of leaf drop and the influx of allochthonous materials from the surrounding terrestrial habitat which occur constantly in the wild aquatic habitats which we attempt to replicate.

We favor a "biology/ecology first" mindset. 

Replenishing the botanical materials provides surface area and food for the numerous small organisms which support our systems. It also provides supplemental food for our fishes, as we've discussed previously. It helps recreate, on a very real level, the "food webs" which support the ecology of all aquatic ecosystems. 

And it sets up botanical-style aquariums to be sustainable indefinitely. 

Radical moves and "Spring Cleanings" are not only unnecessary, IMHO- they are potentially disruptive and counter-productive. Rather, it's about deliberate moves early on, to facilitate the emergence of this biome, and then steady, regular replenishment of botanical materials to nourish and sustain the ecosystem. 

My belief is steeped in the mindset that you've created a little ecosystem, and that, if you start removing a significant source of someone's food (or for that matter, their home!), there is bound to be a net loss of biota...and this could lead to a disruption of the very biological processes that we aim to foster.

Okay, it's a theory...But I think I might be on to something, maybe? So, like here is my theory in more detail:

Simply look at the botanical-style aquarium (like any aquarium, of course) as a little "microcosm", with processes and life forms dependent upon each other for food, shelter, and other aspects of their existence. And, I really believe that the environment of this type of aquarium, because it relies on botanical materials (leaves, seed pods, etc.), is significantly influenced by the amount and composition of said material to "operate" successfully over time.

No expiration date.

Personally, I don't think that botanical-style aquariums are ever "finished", BTW. They simply continue to evolve over extended periods of time, just like the wild habitats that we attempt to replicate in our tanks do.

The continuous change, development, and evolution of aquatic habitats is a fascinating, compelling area to study- and to replicate in our aquaria. I'm convinced more than ever that the secrets that we learn by fostering and accepting Nature's processes and dynamics are the absolute key to everything that we do in the aquarium.

The idea that your aquarium environment simply deteriorates as a result of its very existence is, in my humble opinion, wrong, narrow-minded, and outdated thinking. (Other than that, it's completely correct!😆). 

Seriously, though... 

"Old Tank Syndrome" is a crock of shit, IMHO.

Aquariums only have an "expiration date" if we don't take care of them. Period. No more sugar coating this.

If we look at them assume sort of "static diorama" thing, requiring no real care, they definitely have an "expiration date"; a point where they are no longer sustainable. When we consider our aquariums to be tiny, closed ecosystems, subject to the same "rules" which govern the natural environments which we seek to replicate, the parallels are obvious. The possibilities open up. And the potential to unlock new techniques, ideas, and benefits for our fishes is very real and truly exciting!

I'm not entirely certain how this approach to aquariums, and this idea of fostering a microbiome within our tank and caring for it has become a  sort of "revolutionary" or "counter-culture" sort of thing in the hobby, as many fellow hobbyists have told me that they feel it is. 

Label it what you want, I think that, if we make the effort to understand the function of our tanks as much as we do the appearance, then it all starts making sense. If you look at an aquarium as you would a garden- an organic, living, evolving, growing entity- one which requires a bit of care on our part in order to thrive-then the idea of an "expiration date" or inevitable decline of the system becomes much less logical.

Rather, it's a continuous and indefinite process.

No "end point."

Much like a "road trip", the "destination" becomes less important than the journey. It's about the experiences gleaned along the way. Enjoyment of the developments, the process. In the botanical-style aquarium, it's truly about a dynamic and ever-changing system. Every stage holds fascination.

Continuously.

An aquatic display is not a static entity, and will continue to encompass life, death, and everything in between for as long as it's in existence. There is no expiration date for our aquariums, unless we select one.

Take great comfort in that simple truth. 

Stay grateful. Stay enthralled. Stay observant. Stay patient. Stay dedicated...

And Stay Wet.

Great...Expectations?

By now, this whole idea of adding botanical materials to our aquariums for the purpose of helping create the physical, biological, and chemical environment of our aquariums is becoming way more familiar. Yet, no matter how many times you've created a botanical-influenced natural aquarium, the experience seems new and somehow different.

Expectations are funny things, aren't they?

There is something very pure and evocative-even a bit "uncomfortable" about utilizing botanical materials in the aquarium. Selecting, preparing, and utilizing them is more than just a practice- it's an experience. A journey. One which we can all take- and all benefit from.

Right along with our fishes, of course!

And yeah, it can even be seen as a bit of a spiritual journey, too- leading to some form of enlightenment and education about Nature, from a totally unique perspective.

The energy and creativity that you bring with you on the journey tends to become amplified during the experience. As you work with botanicals in your aquariums, your mind takes you to different places; new ideas for how your aquarium's microcosm can evolve start flooding your mind. Every tank- like every hobbyist- is different- and different inspirations arise. We don’t want everyone walking away feeling the same thing, quite the opposite actually. 

That uniqueness is a large part of the experience.

The experience is largely about discovery. And today's piece is a bit about some of the interesting discoveries- expectations, and revelations that we as a community have learned along the way during our experiences working with botanicals in our aquariums.

Our aquariums evolve, as do the materials within them. We've discussed this concept many times, but it's one that we keep coming back to.

If we think of an aquarium as we do a natural aquatic ecosystem, it's certainly realistic to assume that some of the materials in the ecosystem will change, re-distribute, or completely decompose over time.

Botanicals are not "forever" aquascaping materials. We consider them ephemeral in nature. They will soften, break down, and otherwise decompose over time. Some materials, like leaves- particularly Catappa and Guava, will break down more rapidly than others, and if you're like our friend Jeff Senske of Aquaiuim Design Group, and like the look of intact leaves versus partially decomposed ones, you'll want to replace them more frequently; typically on the order of every three weeks or so, in order to have more-or-less "intact" leaves in your tank.

On the other hand, if you're like me, and enjoy the more natural look that occurs as the leaves break down, just keep 'em in. You may need to remove some materials if you find fungal growth, biofilm, or other growth unsightly or otherwise untenable, or if material gets caught up in filter inlets, etc. However, "operational concerns" aside, and if you've made that "mental shift" and can tolerate the stuff decomposing, just let them be and enjoy!

Botanicals like the really hard seed pods (Sterculia Pods", "Cariniana Pods", "Afzelia Pods"), etc., can last for many, many months, and generally will soften on their interiors long before any decomposition occurs on the exterior "shell" of he botanical.  In fact, they'll typically recruit biofilms, which almost seem to serve as a sort of "protective cover" that preserves them.

Often times, fishes like Plecos, Otocinculus catfish, loaches, Headstanders, and bottom-dwelling fishes will rasp or pick at the decomposing botanicals, which further speeds up the process. Others, like Caridina shrimp, Apistos, characins, and others, will pick at biofilms covering the interior and exterior of various botanicals, as well as at the microfauna which live among them, just as they do in Nature. 

Sometimes, the fishes will use botanical materials for a spawning site.

We receive a lot of questions about which botanicals will "tint the water the darkest" or whatever. Cool questions. Well, here's the deal:  Virtually all botanical materials will impact the color of the water. You'll find, as we have, that different materials will impart different colors into the water. It will typically be clear, but with a golden, brownish, or perhaps a slight reddish tint.

The degree of tint imparted will be determined by various factors, such as how much of the materials you use in your tank, how long they were boiled and soaked during the preparation process, if you're using activated carbon or other chemical filter media, and how much water movement is in your system. However, rest assured, almost any botanical materials you submerge in your tank will impart some color to the water.

Unfortunately, since botanicals are natural materials, there is no "recipe'; no formula  with a set "X number of leaves/pods per ___ gallons of aquarium capacity", and you'll have to use your judgement as to how much is too much! It's as much of an "art" as it is a "science!"

Now, If you really dislike the tinted water, but love the look of the botanicals you can mitigate some of this by employing a lmuch onger "post-boil" soaking period- like over a week. Keep changing the water in your soaking container daily, which will help eliminate some of the accumulating organics, as well as to help you to determine the length of time that you need to keep soaking the botanicals to minimize the tint.

Of course, it's far easier to simply employ chemical filtration media, such as activated carbon, and/or synthetic adsorbents such as Seachem Purigen, to help eliminate a good portion of the excess discoloration within the display aquarium where the botanicals will ultimately "reside."

Another interesting phenomenon about "living with your botanicals" is that they will "redistribute" throughout the aquarium. They're being moved around by both current and the activities of fishes, as well as during our maintenance activities, etc. This is, not surprisingly, very similar to what occurs in Nature, where various events carry materials like seed pods, branches, leaves, etc. to various locales within a given body of water.

In our opinion, this movement of materials, along with the natural and "assisted" decomposition that occurs, will contribute to a surprisingly dynamic environment!

Your aquarium water may appear turbid at various times. We are pretty comfortable with this idea; however, some of you may not be. As bacteria act to break down botanical materials, they may impart a bit of "cloudiness" into the the water. Also, materials such as lignin and good old terrestrial soils/silt find their way into our tanks at times.

Some of these inputs, such as soils- are intentional! Others are the unintended by-product of the materials we use, The look is definitely different than what we as aquarists have been indoctrinated to accept as "normal." One of my good friends, and a botanical-style aquarium freak, calls this phenomenon  "flavor"- and we see it as an ultimate expression of a truly natural-looking aquarium. 

Yeah, the water itself becomes part of the attraction. The color, the "texture", and the clarity  of the water are as engrossing and fascinating as the materials which affect it. It's something that you either love or simply hate...everyone who ventures into this method of aquarium keeping needs to make their own determination of wether or not they like it. 

Need a bit more convincing to embrace the charm of the water itself in botanical-style aquariums?

Simply look at a natural underwater habitat, such as an igapo or flooded varzea grassland, and see for yourself the allure of these dynamic habitats, and how they're ripe for replication in the aquarium. You'll understand how the terrestrial materials impact the now aquatic environment- the function AND the aesthetic-fundamental to the philosophy of the botanical-style aquarium.

Speaking of the impact of terrestrial materials on the aquatic habitat- remember, too, that just like in Nature, if new botanicals are added into the aquarium as others break down, you'll have more-or-less continuous influx of materials to help provide enrichment to the aquarium environment. This type of "renewal" creates a very dynamic, ever-changing physical environment, while helping keep water chemistry changes to a minimum.

This is the perfect analog to the concept of "allochthonous input" which occurs in wild aquatic habitats- materials from outside the aquatic environment- such as the surrounding forest- entering and influencing the aquatic environment.

The fishes in your system may ultimately display many interesting behaviors, such as foraging activities, territorial defense, and even spawning, as a result of this regular influx of "fresh" aquatic botanicals. You could even get pretty creative, and attempt to replicate seasonal "wet" and "dry" times by adding new materials at specified times throughout the year...The possibilities here are as diverse and interesting as the range of materials that we have to play with!

Go into this with the expectation that you might get to experience an entirely different way of looking at aquariums- and the natural environments we try to replicate- and you'll never be disappointed.

It's all a part of your "life with botanicals"- an ever-changing, always interesting dynamic that can impact your fishes in so many beneficial ways.

Stay dedicated. Stay excited. Stay engaged. Stay resourceful...

And Stay Wet.
