I'm looking for advice on stocking my 30-gallon tall hex aquarium. I initially bought it to fill with schooling fish, and had a school each of neon tetras, harlequin rasboras, rummynose tetras, and spotted cories. The neons all bit the dust when my heater broke and kicked the tank temp up to near 90 F. I recently replaced those neons by doubling the size of my rasbora school, but apparently they brought disease to the tank and down went all of my rasboras and rummynoses. Also my beta.
At this point I have a medium-sized leopard Sailfin Pleco
, 6 spotted cories, a Pearl Gourami
which is probably about to succumb to the same disease which killed everything else, and a Kribensis
that got ejected from my 55 gal for bad behavior. Lots of tall plastic plants for decoration. I'd really like to take this tank in a new direction. I've never really been happy with it. I keep it on a counter top where you can view it from just about any angle, yet I never feel the urge to look at it. The tank has a very tall water column for its size, over 24", but none of my fish occupy the top half.
I think I want to ditch the plants and go to a rocky tank, but I don't know what would be suitable for that tank size and environment. I've thought about shell-dwellers, but I don't think they'd ever make it to the top of the tank. Anyone have any suggestions for stocking this unusually shaped tank?
