It is quite possible for Ocellaris Clown to form a relationship with a BTA. Mine are. They spawn readily and I raise their offspring. You may have to kinda of chase them around the aquarium so that they feel a little bit threatened. Mine did not coexixt until I moved the aquariuma dn they gor spooked. They have never left is 2.5 years. If you need any other help let me know.
Cool thanks for help. But I have one more question. Do different colors of BTAs appeal more or less to them? Because I heard there are even better chances with a rose bubble.
That I really do not know. If a fish store told you that it could be the price difference. About 3-4 times more for a rose. Mine is just a regular old BTA. I'll send you a pic. Give it a shot and keep me posted. I want to know if what I did will work for others. When I moved my tank the clowns and anemone were the last to go. They were in that anemone quickly.
