Thanks all, I know, we thought she was Male as she was growing! She's a don conkral fish. Feed them all a very varied diet inc a mixture of hikari pellets, mussel, prawn, squid, river shrimp, koi sticks, then some cucumber and catfish pellets they steal!-) weekly 50% water changes I think help... Prob mostly her genes tho. If they breed let me know if you want some fry if your in the uk anyone! Cheers.
