Common pennants (Heniochus monoceros )

The masks Pennant (Heniochus monoceros ) is a species of the family of butterfly fish.

The fish has a white, high-backed and laterally flattened body. The front white part of the dorsal fin is not as extended as in other long banner fish. From there, three broad, black stripes run to the root of the tail fin to the black pelvic fins and snout. He has ever a thorn-like outgrowth on the eyes. Caudal fin, dorsal fin and the rear part of the anal fin are yellow.

The mask pennant fish reaches a length of 18 to 24 cm. He lives in the Indo-Pacific, from the coast of East Africa, Mauritius and to the coral reefs, in southern Japan, northeast of Papua New Guinea, the Great Barrier Reef, the coast of New South Wales and Tahiti. He can always be found near the coast and preferred reefs with strong coral growth. Juvenile fish often live alone, adult pairs.

It feeds on bottom-dwelling invertebrates.
