Copperband Butterflyfish

Copperband Butterflyfish

Species: Chelmon rostratus

Origin: Indo-Pacific

Family: Chaetodontidae

Overview:

The Copperband Butterflyfish, also known as the Beaked Butterflyfish or Orange Stripe Butterfly, is easily recognized by its elongated snout and bold yellow-orange vertical stripes. Its distinctive false eyespot on the rear dorsal fin helps confuse predators in the wild. This species is a striking addition to peaceful marine systems and is sometimes introduced to control nuisance Aiptasia anemones.

Due to its shy nature and specialized feeding habits, the Copperband is considered a difficult fish to keep and is best reserved for experienced aquarists. It is a slow and deliberate feeder that often requires a variety of frozen and live foods to begin eating in captivity. Best housed in large aquariums of 125 gallons or more, this fish should be kept singly and not with other butterflyfish or aggressive tank mates. While considered “reef safe with caution,” it may nip at anemones, feather dusters, and other sessile invertebrates.
