Description

The Chevron Butterflyfish (Chaetodon Trifascialis), also known as Triangulate Butterflyfish or V-lined Butterflyfish, is a species of Butterflyfish found in the Indo-Pacific from the Red Sea and East Africa to the Hawaiian and Society Islands.

Chevron Butterflyfish or Triangulate Butterflyfish adults have an elongate white body with narrow chevron markings and may be up to 7″ inches in length. Juveniles have a mostly yellow tail and a broad black band extending from the rear of the dorsal fin to the rear of the anal fin. The tail pattern and the coloring of the posterior part of body changes dramatically with growth, with the tail entirely black with a thin yellow outline and the hind part of the body not differing in color from the areas further forward in adult Chevron Butterflyfish or Triangulate Butterflyfish.
