There are varying opinions on elegance corals. I have one and have it under pc lights high in my tank and in a medium flow area. I've had it a year and it has doubled in size. I feed Dt's phyto and direct feed mine silversides about once a week. Also, I soak all my foods in zoe. Good luck, they are awsome corals! After silversides it closes up for awhile, then expands HUGE!
