Some copperband butterflyfish (Chelmon rostratus) eat Aiptasia. Not all copperbands are enthusiastic about this food item, so success might require some time, or a few fish. Copperband butterflyfish can be very difficult to keep, and should be housed in an aquarium of at least 75 gallons. Some aquarists report better success with larger (180 gallons or more) tanks. They sometimes refuse to eat, and those that do may require live food, at least initially. In some cases, they die even if feeding.
These fish are not always reef-compatible, and might eat anemones, tube worms, and feather-dusters, and can pick on corals, snails, and clams. In addition, they are not always compatible with certain fishes, such as tangs.
