Description

Juveniles are olive-green above and white below. They have bright orange spots on the head and belly. There is a dark brown stripe from the mouth to the eye. A series of narrow white bars extend from the dorsal fin onto the top of the body and there are three black ocelli on the front, middle and rear of the dorsal fin.

Females have a grey-greenish body and irregular blackish bars on the back. There are irregular pink bars on the face, a vertical elongate black spot behind the eye and a black bar on the pectoral fin base. They also have three black ocelli on the dorsal fin.

Males are similar to the females, but have a greener body and may lose some of the ocelli in the dorsal fin.

Very pale when on white sand substrates.
