I used to feed mine small Krill.....it was really neat to watch it eat it. At night when you see the tenticles out...pass a little thawed krill over them and it will close up on it like a clam.......I feed mine about every three days. It was on the bottom under 260watt lights in a 75 gallon and it did really good. Kind of sensitive to other corals in their area so make sure that nothing else is really around it. They like good cal. levels too. Get them too low and it will shrivel up like an old man.
