I have an empty 29, since I moved my GT to the 75. I would like to do something with it, instead of just leaving it empty. Could a Leopard Ctenopoma (spotted climbing perch, spotted bushfish) live in it, or is the tank too small? If it won't work, what else could I put in the 29? I'd like something interesting, but I don't really want small cichlids or a community. Any ideas?
