Identification

The Vagabond Butterflyfish has a white body with two series of narrow dark lines set at right angles. A broad black band passes through the eye and yellow horizontal lines cross the interorbital region. A black band is present at the rear of the body and another through the caudal fin. The soft dorsal, anal and caudal fins are yellow.

Juvenile Vagabond Butterflyfish resemble the adults, but have a black spot at the rear of the dorsal fin.
