i have a 55 gallon tank with 3 fantail golfish that are about 4 inches and 1 fantail that is about 1 inch. any suggestions on what kind of fish i can mix with them? and please DO NOT tell me other golfish! if it ends up that i cant mix anything with them then i am definitely getting rid of them. i want more variety and color! if the idiot that sold them to me had told me i couldnt mix them with any other fish i wouldnt have gotten them in the fist place!
