I purchased a purple-tipped Haitian anemone day before yesterday. I acclimated it properly, and placed it on a rock high in the tank. Later that night it fell off. Yesterday morning I found it lying on my short tentacle plate coral, so removed it and placed it on another rock low in the tank. The anemone did not stick, and today it is shriveled up tiny and is not attached to anything, although it still has all of it's color. Help!
