Keep it low in the tank. On a small rock on the sand would work. Or you can attached it to the side of a rock next to the sand. It has stinging sweeper tentacles, which can be several inches long, so don't place it near any other corals. You will see the sweepers come out after lights turn off. Feed it weekly and it will grow faster. Feeding small bits of food, sized for those corallites (eyes) would work. Mine eat mysids, brine shrimp and even krill. Feed right when lights turn out. Watch out for shrimp or fish that may snag the food from the corals mouth. This coral can take a good 5-10mins to SLOWLY digest the food you give it. In that time a opportunistic shrimp, crab or fish might find an easy meal to snag from the coral.
