Chelmonops is a species of butterfly fish (Chaetodon)that is poor in species and has only two very similar species. Both species live on the subtropical and temperate coasts of Australia and are a little over 20 centimeters long. They are high-backed and drawn in a pattern of wide, black to brown and silvery white stripes. The dorsal and anal fins are pulled out and still emphasize the tall body. The muzzle is long. Adult Chelmonops are territorial and live in pairs in rock and coral reefs , estuaries and sheltered bays. Young fish are solitary and have a large eye-spot in the soft-rayed part of the dorsal fin . Chelmonops feed on algae and small invertebrates. They are closely related to the tropical pincer fish of the genus Chelmon and are considered to be their sister group .
