I'm heading up to Milwaukee to go to Hoffers, what I've heard to be an amazing store. Now I know my angel will eat my neons and I may actually transfer them, but that leaves the real question about other fish. Can I fit anything else into here, and if so, would a few rummy-noses work? I don't wanna be flamed, I'm just asking a question. And I hear these are great schoolers, but are they hypercative like danios? Because I really want a fairly calm fish. Any suggestions other then them?
