I'm getting my new 75gal on Monday to replace the one my wife broke last year. Heres my delema. Should I move my tanganyikanks into the 75 gal then move my community fish, which are mixed with my SA/CA cichlids in my 66 gal, into the 55 where the tanganyikans were, and leave my SA?CA in the 66gal. Or move my Tanganyikans in to the 66 gal and move my SA/CA into the 75gal. Any Ideas?
