Hey everyone, about a week ago my clownfish started fighting. Ive had my clownfish for about two years now, and they have never fought before. My smaller clownfish is now picking on the bigger one. They are similar in size, but one is a little bigger than the other. The bigger ones fins are getting tattered and now spends most of the day hiding from the other. They used to swim together and sleep together for the last two years, but now they don't. Im wondering if I should be doing anything to keep them from fighting, or if I should remove one of the clowns. Thanks! My tank is a 93 gallon cube btw.
