I am wondering if any of you have experience with/think that it would be possible to have a 6G (Eclipse) SW tank (FOWLR) with only one (maybe 2) fish (eg: small clown, small goby, something along those lines.) I wouldn't be using the factory filtration (I would upgrade to something else) or lighting (again, would be ready to try to upgrade - though I am not planning on growing corals or anything like that.) I understand that often tiny tanks are much less forgiving in terms of water parameters and such, but otherwise, any ideas?
