I have a percula clown fish and I have had it about 3 weeks now. About 5 days ago I came home and the clown fish was in my sebae anemone. It seemed as if the fish was going to host the anemone. When I woke up the next day the clown wasn't on the anemone and hasn't gone back to its since. Is there a reason he wont go back? When he was in he kept swimming and rubbing through it. Now he doesn't seem interested in it anymore. Why wont he host there at night even?
