You've probably heard the old saying,"You can lead a horse to water but you can't make it drink"? Well, substitute clown for horse and carpet anemone for water and you have your answer.
Seriously, there doesn't seem to be any way to tell what, or if, a clown will adopt an anenome or coral. My clown adopted my hammer coral, for example. You just have to wait an see what the clown wants to do.
By the way......great looking CA and very nice tank.
