Let's get real...

I tend to keep my "ears to the ground" to follow some of the goings-on in the aquarium world, and sometimes, I pick up on things which really get me thinking. 

And, I admit that it's been more than a minute since I've made an observation or two that called out something that I find a bit "concerning" to me... lol

One of the things that sort of catches my attention lately is the increasing interest in what is being labeled as "realism" among the "high concept" aquascaping world. Like, taking some cues from natural habitats to incorporate in aquariums. Part of me is totally celebrating the move away from the strange "fantasy scape" crap that has dominated aquascaping for years now.

It's an interesting shift. An encouragung one.

However, the natural-style aquarium lover in me is still wishing we could prod them along a bit. While it's an interesting and encouraging development, I can't help but observe some nuances in the "movement" which leave me wishing they'd go a bit further. Because the emphasis seems to be on only half of the equation.

Yeah, the interest seems to focus mainly on the look, as opposed to the whole picture; the function.

I mean, "baby steps", I suppose- but man, going just a bit further could yield so much more...

I guess it seems like nothing ever satisfies me, right?


I sometimes fear that this burgeoning interest in aquariums intended to replicate some aspects of Nature at a "contest level" will result in the same sort of "diorama effect" we've seen in planted aquarium contests. In other words, just focusing on the "look" (which is cool, don't get me wrong) yet summarily overlooking the function- the reason why the habitat looks the way it does and how fishes have adapted to it...and considering how we can utilize this for their husbandry, spawning, etc. is only a marginal improvement over where we've been "stuck" for a while now.

We need to go further.

I'm sure I'm being just a bit over-the-top, but the so-called "nature aquarium" movement seems to have, IMHO, largely overlooked the real function of Nature, so there is some precedent, unfortunately. A sanitized, highly stylized interpretation of a natural habitat is a start...but it's just that- a start.

The real exciting part- the truly "progressive" part- comes when you let Nature "do her thing" and allow her to transform the aquarium as she's done in the wild for eons.

So, yes- It should go beyond merely creating the "look" of these systems to win a contest, IMHO. Rather, we should also focus on the structural/functional aspects of these environments to create long-term benefits for the fishes we keep in them. We should aim to incorporate things like biofilms, detritus, decomposition into our systems, just as Nature does.

That's a real "biotope aquarium" in my book.

And there is a group of hobbyists that are in a position to influence and inspire the aquarium world to push further- biotope enthusiasts.  I hope that this crowd- who have a lot of awareness about the habitats they are inspired by-will at least consider this "functional/aesthetic" dynamic that we obsess over when they conceive and execute their work, and be more vocal about it.

Decomposing leaves, biofilms, detritus, sediments, submerged terrestrial plants- all have their place in an aquarium designed to mimic aquatic habitats.  You can and should be able to manage nutrients and the bioload input released into our closed systems by these materials, as we've discussed (and executed/demostrated) here for years.  The fear about "detritus" and such "crashing tanks" is largely overstated, IMHO- especially with competent aquarium husbandry and proper outfitting of a tank with good filtration and nutrient control/export systems in place.

If you're up to the challenge of attempting to replicate the look of some natural habitat- you should be a competent enough aquarist to be able to responsibly manage the system over the long term, as well.

Ouch, right?  

Hey, that's reality. Sorry to be so frank. Enough of the "shallow mimicry" bullshit that has dominated the aquascaping/contest world for too long, IMHO. You want to truly influence/educate people and inspire them? Want to really advance the hobby and art/science of aquarium keeping? Then execute a tank which can be managed over the long haul.

A tank that doesn't polish out the reality of Nature. Crack the code. Figure out the technique. Look to Nature and "back engineer" it. These things can be done.  You-our community- are doing them right now.

There are many aspects of wild habitats that we choose to replicate, which we can turn into "functionally aesthetic" aquarium systems. Take, for example, the most common hardscape component- wood. It's been a staple of the aquarium world for decades. If we think of wood pieces as more than just "static hardscape"- and consider them as a dynamic part of the habitat- the game changes.

Trees- in their submerged and even fallen state- are more than just "hardscape" to those of us who are into the functional aesthetic aspects of our aquariums. Much more.

The trees present in flooded forest habitats and streams actually benefit fishes and aquatic life forms when they fall. Upon the return of the inundating waters to the dry forests, these fallen trees become an important part of the aquatic habitats, providing multiple benefits.  A fallen tree wedged into a stream bottom provides shelter from the currents. The tree trunk changes the flow pattern of the stream to create eddies which may bring in food and wash away fine silt, allowing formation of gravel beds and the accumulation of leaves and fallen botanical materials. 

Foraging areas are created, in which fishes may find insects, small crustaceans, and fruits and such which come from the terrestrial environment. They provide spawning locations for fishes, and shelter for fry to develop and avoid predators.

Although it might be impractical for many aquarists to obtain really large branches and such to simulate these submerged tree trunks, it would be a most interesting aquascape feature if you could source larger, thicker pieces to recreate this fascinating microhabitat in your aquarium! And entire community of fishes could be developed around (literally) one or two large branches in a modest-sized aquarium.

Toss in a bunch of leaf litter and some botanicals- let them break down and decompose...bam! Instant functional biotope component!


Well, almost...You've got the look down.

Foster the function! 

Encourage some biofilms, algae, and other epiphytic material to colonize the branches and then you're on your way to a functional representation of this unique habitat!  "Polishing out" and "editing" the "undesirable" aspects of Nature (again, the biofilms, detritus, decomposition, etc.) for the sake of some "aesthetic benefit" is, in reality, counterproductive to long-term aquarium management.

For the "nature aquarium" crowd- please focus on one of Amano's core principles- one which has just been sort of "cast aside" of late- the concept and philosophy wabi-sabi. One that embraces the beauty of transience and natural processes.

Making the mental shift and helping the aquarium world as a whole understand and appreciate the appearance of some formerly misunderstood and feared aspects of aquatic habitats will lead to more than a shallow, superficial interpretation of Nature. It will lead to aquarium interpretations which foster many of the functions which occur in Nature. 

It's about moving beyond looking at a natural feature and thinking just about how to create the way it looks in our aquariums. It's about looking at that feature and thinking, "How can I utilize this feature to provide the same function in the aquarium that it does in Nature?"

So much to talk about, study, and interpret here.

There are so many unique and compelling aspects of the natural aquatic world that I just know will unlock the secrets of many unique and beautiful fishes which we keep in our aquariums. By providing functional natural aquariums, we're really setting the stage for what I really feel is the next great evolution of aquarium keeping: 

Creating aquariums which replicate, as realistically as possible, the look and function of the aquatic habitats that we are fascinated by.

SO, yeah...there is a lot to be gained when we really "get real."

Go deeper...push yourself just a bit further.

You might just change the entire aquarium hobby.

Stay inquisitive. Stay curious. Stay excited. Stay fascinated. Stay bold...

And Stay Wet.
