it is a BTA, bubble tip anemone. and while they aren't a natural host anemone for ocy clowns most will go into them. it took mine 9 months but they found mine and now never leave it. don't force the clowns into the anemone though just let nature take it's course, may take a day or may take a year if they ever do decide to use it. either way it is a nice looking anemone, good luck.
