Ideally I’d like to add a fire fish, yellow head jawfish, some clown gobies and a green chromis but I feel like it would be a fish or two over cause I got the six line and a clown fish now. Oh and ya putting just one tang in a tank like that is pretty messed up like ya I would love a blue tang but just too much for a tank that size.This is the correct answer. And for me, ‘bigger’ means an adult ocellaris or cardinal, or if really pushing it a pygmy angel. Smaller would be most gobies, smaller blennies, fire fish, etc. When I look on the biocube group on FB, there are constantly people posting their tanks that have 2 or 3 (I’ve seen as many as 5) tangs in a 32 gallon biocube, it’s just wrong.
Right now I’ve got a 28g nano cube, and it’s got a banggai Cardinal, six line, pink bar goby, and a Tailspot blenny, I may add one or two more small fish (thinking a ruby red dragonet and/or a fire fish), but I’m not married to the idea either.
