I just added a second clownfish to my tank. He is smaller than the first but it is not going well. The first one chases him and keeps him cornered. The new fish is eating but looks so tired. He is not getting nipped but the original clown turns backwards and whacks him with her tail if he tries to swim around. Would adding an anemone help with this? It has only been two days but i don’t like this new behavior. Thanks for any help.
