I bought a pair of ocellaris clownfish at my LFS on Thursday. Currently it is Sunday, but today is the first day I have seen such behavior like this. One fish is slightly bigger and the bigger one is nipping the fins on the smaller one. My LFS told me to put the aggressive one into the net for 10 minutes if this were to happen. I did as directed, but it didn’t help a bit. What do you guys propose. I want 2 healthy and loving fish that will be able to live peacefully in a soon to be reef tank, not 2 fighting aggressive fish. What should I do?
