Oh man, great idea.
What if I make my next tank a catfish only tank? Just a bunch of different small, peaceful species occupying different levels of the tank? I’d just have to look into compatibility.
Picture it, though. A big tank with a huge tangle of plants and driftwood taking up about 2/3 of the tank (peninsula style) with different little catfish drifting and darting in and out?
I could have a little shoaling species to occupy the mid-upper levels of the tank, like Hyalobagrus flavus or Kryptopterus vitreolus or Pareutropius buffeii. (Maybe two different kinds?)
And a Farlowella vittata or something similar to hang out on the driftwood.
And I could have a solitary bottom dwelling cat (like Dexter, but probably smaller) or maybe another shoaling species like a Corydoras species…hm.
OH MAN, if I found Nanobagrus armatus anywhere I could put them in here! That’d be so great! (Though I’d still want a species tank for them for breeding.)
So many options. Leaning towards the two asian species I mentioned as a basis, since I seem to have a preference for asian fish in general (Only my bristlenose in Dexter’s Tank isn’t asian), though I really liked the idea of getting a farlowella…But to keep one, I’d need to have the shoaling species at the upper end of their pH and temp ranges and the farlowella at the very bottom of it’s range, which isn’t something I’m fond of doing…
But oh man, I love this idea. I love catfish. This is an exciting thought.
