So I have a pair of clowns. They are already paired and have been existing well together for months now. Recently the bigger of the two has started to bully the small one. His fins have been ripped up and his chin looks shredded. Thus has been going on for awhile now. I didn't think much of it at first and contributed it to the fact that I added some new coral that the big one became extreamly possessiveness over. But I'm also not sure if this is the reason because the two would often share anemones but not it's like they have unpaired? Can this happen?
