They also have two blue stripes on their faces, one of which passes through the eye and the other of which is located right next to it. The juveniles have a bluish-black overall color and tiny, curving lines on their bodies that range in color from white to blue. The anal fin has three spines and 20 soft rays, compared to the dorsal fin's 13 spines and 20–21 soft rays. The longest overall length of this species is 45 cm (18 inches).
