Hey all, I picked up a 40 cube (drilled with 20 gallon sump) and am trying to decide what to do with it. The original inspiration for the purchase was to build a setup for a Fuzzy Dwarf Lion. I've also thought about a small puffer. The tank is rimless and won't have a canopy, so whatever is in there can't be a jumper. Any other "nano" predator fish I should consider? I assume that whatever I get will likely live alone or with minimal accompaniment since it seems most lions, puffers and whatnot don't play well with others in this size. For the other stuff, I might do some softies or LPS, but nothing that requires intense flow or intense lighting.
