I have these 5 fish, 2 gold gouramis, 1 male 1 female, 1 dalmation molly, male, and 2 creamsicle mollies, i believe both female. My problem is, the really large gold gourami, the female, is agressive and harasses the other fishes. Ive had the gouramis the same amount of time and the others about a weekish. What should i do?
