I have a true percula clown that has been with a bulb anemone(I think?) for over 2 weeks, not leaving it unless there was food present in tank. I noticed yesterday that the clown wants no part of the anenome...any reasons this may be the case? He seems to stay by the anemone but prefers to stay behind the rock. They both still actively feed. Can an anemone at some point reject a clown after being with it for long period of time? The guy I bought them from said they have been tank mates for over 4 years! Any input is appreciated! Thanks
