I've recently been keeping a close eye on a small (smaller than a dime)white starfish in my tank. He is one of the type that you would commonly see in live sand. Well, over the last week or two, it's been crawling over my pink zoas. At first I thought he was just transiting, but now I think he's actually munching away as they are "disappearing". Has anyone experienced this as well. I never thought a star would want to eat my zoas.
