Now that I've moved my 2" dempsey into the larger tank, I have an available 20gal tank with some giant danios... what cichlids should I try? I'd almost be interested in breeding some dwarfs or something like that. Unfortunately the LFS around here don't have a good selection of cichlids to choose from. The do have some bolivian rams... should I buy a few and see if I get a pair? Would 2 pair be pushing it for this size tank? My water specs are: PH ~7.5 and gk/kh are very low (less than 5 or 6 degrees for either).
