So I noticed one of my clowns missing yesterday and another floating in stress in my tank. I took the one in stress out of the tank and put him in the quarantine. He seemed fine by the end of the night but when I put him back in the tank the 6 line came over and attacked him. I am thinking maybe the 6 line who I thought was being a great member of the tank might have done this to both clowns. Before I remove him from the tank can anyone think of a reason to keep him?
