the closest look to an anemone IMO is frogspawn or torch coral.. somthing of that nature.. which they have been known to host.. However they will choose what they want if you have other options.. I have torch.. frogspawn.. hammer.. leathers.. GSP.. and tons more corals along w/ a perfectly good RBTA.. but as i said before my percs decided to host my green shrooms.. go figure lol
