Copperband Butterflyfish (Chelmon rostratus)

The Copperband Butterflyfish, also known as the Beaked Butterflyfish, Beaked Coralfish, or Orange Stripe Butterfly, has a long, narrow nose and mouth used for hunting into crevices and holes for food. The Copperband Butterflyfish has yellow-orange vertical bands with a black edging. It has a false eyespot on the rear of the dorsal fin. This is a difficult fish to mistake for any other.

It is best housed in very large reefs, or in peaceful community tanks. It should be kept singly, not with conspecifics or similar butterflyfish, and should not be kept with any stress-inducing fish. Caution should be exercised if housing these fish in a reef aquarium. They may pick on invertebrates, especially anemones and feather dusters. They are an excellent fish when used to control aiptasia, or glass anemones, in the reef aquarium.

The Copperband Butterflyfish is a difficult fish to feed; it is a shy and deliberate feeder that may need a variety of foods offered to it in order to start feeding.
