jorgeldelapaz, that BTA looks too small and unhealthy to be hosting a clown. I would suggest you isolate it from clowns and provide excellent conditions to give it a chance to return to good health.
rgentry123, ocellaris is not found with BTAs in the wild at all. I would say there's a chance it will go to the anemone, but definitely not a sure thing. It's been my experience, that when you add a natural symbiote, such as maroon, tomato or clarkii with a BTA, the fish will be in it within minutes (makes no difference whether it is captive bred or wild caught).
