My husband bought his much longed-for rams yesterday. On the advice of the fish shop a male & 2 females. The male sees off both females a bit, the one female doesn't seem to be aggressive at all. The largest female is evil! She chases the other male and female constantly but also my glowlight tetras and even my poor little pygmy cories are getting a good ramming, she actively seeks the other fish out. She completely stressed my 3 female bettas yesterday but they have decided they have had enough today and she is leaving them alone now. Will she settle down? I though Rams were peaceful!!
