to answer your question it is copperbanded butterflys that eat aiptasia, but they are sometimes difficult to get to eat and i have used peppermint shrimp with success. imo that is the route you should take. if you have to ask the name you don't know enough about this difficult to keep fish to get one for a current aiptasia problem. read up on the fish and learn about what to look for in a healty specimen, then wait until you see one, then have the fish store let you watch him eat, then hold him for at least a week. be prepeared for special feedings
