through line (N): "A common or consistent element or theme shared by items in a series or by parts of a whole."
I recently returned from another speaking gig.
This time, I was in St. Louis, Missouri, in the midwest of the U.S. I visited a club with some very advanced, super-talented hobbyists, some who are icons in various hobby specialities. It was a lot of fun, as they almost always are. However, this one- THIS trip- left me with some really profound revelations about the hobby which I'm still processing.
An added bonus is that I was able to visit the amazing botanical method aquariums of our friend, Melanie Holmes. It was beyond satisfying to see a truly talented hobbyist find Her way in the hobby, evolving from "traditional" planted aquascaped tanks into the botanical method.
Observing her work, it was easy to see how Her skill from one "genre" translated into our little speciality. The "through line" was a great understanding of the ecology of aquariums. Here tanks were a celebration of life, aesthetic, and ecology. Any one of them was among the best botanical-method aquariums ever created, IMHO.
I was also able to visit a fish room of a very advanced killifish breeder, and it was not only educational for me, it was enlightening...I took particular note of the techniques and approaches that he was utilizing to manage a large number of aquariums, and to keep a "work flow" of fishes going at all times.
Perhaps what was most memorable to me was how he made adjustments to his techniques, like inducing spawning, egg collection, incubation, and production of live foods.
His function-first approaches to light and temperature manipulation, egg collection, incubation approaches, and even how fry were reared- all demonstrated a keen understanding of the needs of his fishes, and an understanding of the environments- and environmental cues- which the fishes needed to trigger spawning events.
Although the process was more "methodical" than "natural", in that it involved sort of "deconstructing" how Nature works in the wild- all of the techniques he employed were simply practical and simple recreations of natural processes to accomplish what Nature does-just in a more "controlled" manner.
Killifish, IMHO, are the ultimate example of how fishes are intimately tied to their habitats. The techniques which modern killie keepers utilize to spawn their fish, incubate the eggs, and rear the resulting fry are a direct distillation of an understanding of this relationship.
Indeed, there was a "through line" of sorts, running from the wild savannah pools and forest streams of East Africa, to the tightly-controlled environment of this suburban St. Louis basement.
It was profound. It was inspiring. It was amazing.
Now, sure, I wasn't seeing fishes being kept in tanks with accumulations of leaf litter over a shallow sedimented substrate, with overhanging terrestrial vegetation. Literal recreations of their natural habitats. Rather, I was seeing the pragmatic application of "biotope replication!" Yeah, it doesn't always have to look like it to function like it!
A huge "unlock" for me, really.
What we've longed called "natural" in the aquairum hobby can take on more than one meaning. I mean, I have consistently railed on the use of the term "natural" when those "high concept", artistically-styled "Nature Aquariums" are proferred to us as "natural" for some very specific reasons; in particular, the fact that they are often touted as "looking just like Nature", an assertion which makes me want to vomit. They generally don't look like wild aquatic habitats.
They're simply beautiful aquariums, skillfully executed.
However, I really can't deny that, on a purely ecological level, they DO function like natural aquatic systems to a certain extent, relying on energy/nutritoinal inputs, and yielding growth of aquatic plants. It's just again, a sort of "deconstructed" approach.
I think that it's the "cultural arrogance" and embrace of the most superficial aspects of aquarium keeping, coupled with the constant assertion that these tanks "look like natural aquatic habitats" by the proponents who surround the "Nature Aquarium" movement, which has always turned me off about them.
Not the work itself.
The reality is that these systems do require the aquarist to reproduce natural processes to some extent in order to be successful. An understanding of the ecology of aquatic plants and their environment is necessary.
Another "through line" from Nature to aquarium...
And of course, there is what we call the "botanical method"- an approach that seeks to more literally recreate the ecology of wild aquatic ecosystems in the aquarium.
To a certain extent, it's the "oldest game in town" in the aquarium world- the approach which lovers of aquatic life centuries before us took to keeping fishes: Toss in some soil, leaves, twigs, and plants and attempt to recreate the wild aquatic habitat as accurately as possible. We incorporate these materials in our tanks because they're what's found in the environments from which our fishes come, right?
Yeah. An homage to Nature by attempting to replicate the function of Nature. And making the effort to understand the relationship between fishes and their habitats.
It's not some arcane idea, is it?
A "through line", for sure!
All we are doing with any aquarium, wether we are conscious of it or not- is attempting to reproduce the functions of natural aquatic ecosystems in our tanks.
The idea of creating a multi-tiered ecosystem, which provides a lot of the requirements needed to operate successfully with just a few basic maintenance practices, the passage of time, a lot of patience, and careful observation- is something that has been discussed, but rarely executed in the modern aquarium hobby until quite recently...
Not because it's difficult to execute.
Not because it's hard to grasp the underlying concepts.
It's because it's difficult to try something which seems so "contrary" to what we are constantly exposed to in social media and elsewhere. It means doing something which we may find uncomfortable, because we're told it's "dangerous" or "reckless" or "dirty" or whatever, by pundits who neither understand nor appreciate what it means to embrace a truly natural, ecological approach to aquarium keeping.
It means adopting a different outlook, accepting a different, yet very beautiful aesthetic. It's about listening to Nature instead of the dude on Instagram with the flashy, artistically-presented, gadget-driven tank. It's not always comfortable at first for some to try, and it initially seems like you're somehow doing things wrong.
Yet, executing this type of tank is about as basic as aquarium-keeping gets.
The difficult part is understanding that this is an extremely natural, ecologically beneficial process, and accepting that it does facilitate the appearance of some things that you might not be comfortable with initially (like, cloudy water, fungal threads, biofilms, decomposition...all that stuff!). Making those mental shifts to accept something different than what the aquarium hobby establishment has proffered as the way to go for generations...
Yet it's not that different than what our distant ancestors did when they set up what we now refer to as an "aquarium."
A through line...one which requires mental shifts and adoption of a long-term mindset.
You have to give things time to establish and settle.
It's about patience.
It's about faith.
Faith in Mother Nature, who's been doing this stuff for eons. Faith that you're doing something which embraces Nature's processes so fully.
The truest, straightest "through line" there is in the aquarium hobby.
Stay diligent. Stay curious. Stay observant. Stay patient. Stay engaged...
And Stay Wet.
