It is a condylactis. I may have to see about gifting him to someone then. ThanksTank looks great! I believe that is a green Condylactis anemone. When they get a little larger they are know to eat fish, inverts, and can be quite aggressive. Might want to watch out for that little guy. If you don't have one, sand stars are great to have to keep your sand nice and clean. Happy reefing!
