i recently purchased a female betta for my 55 gal. tank. at my LFS they said the the females were extremly peaceful. and i have not seen anythign to doubt that but I've been reading on here and people have been saying its bad to mixs females bettas with other fish. is it? They are also in the tank with two newly aquired blue gourami that as far as i can tell are both female as well. They seem to get along fine and even one gourami seem sprotective of the betta let me know please
