The Chevron Butterflyfish Chaetodon trifascialis is a handsome fish known and named for its beautiful diagonal chevron design. It is one of the more elongate butterflyfish in the genus. Yet it is moderate in size, reaching a total length of only about 7 inches (18 cm). This is a striking species with its elegant form, graceful swimming movement, and alluring colors.
The silverish white body is touched with yellow around the perimeter and there is a broad dark band running through the eye and another on the tail. But its primary feature is the numerous chevron-patterned lines. These decorative markings have led to a number of common names including Triangulate Butterflyfish, V-lined Butterflyfish, Rightangle Butterflyfish, and Chevroned Butterflyfish. Also because this pretty butterflyfish is found in its natural habitat swimming among table corals of the Acropora species, it is called the Table Coral Butterflyfish and Acropora Butterfly.
