You know, I also wanted nems mainly for the clownfish / anemone symbiotic relationship. When I did find the right BTA for my tank my clowns did not want to have anything to do with it. They LOVE their toadstool leather coral and would have nothing to do with any mere BTA. The great thing about that is you don't have to worry about where the toadstool may end up in the morning. Much more than you can say for anemones. I ended up selling and trading my anemones off because sooner or later they would take to wondering around. Besides, the clowns thought they were stinky or something.
