Épines dorsales (Total) : 9; Rayons mous dorsaux (Total) : 12; Épines anales: 3; Rayons mous anaux: 12. Upper half of the body with 3 blackish bars; dorsal and anal fins and dorsal edge of caudal fin with pink margin; forehead with a median pale blue line. Dorsal fin incised between 2nd and 3rd spines; approximately 1/3 the length of the 2nd spine, the gap about 1.5 times larger than between 1st and 2nd or 3rd and 4th spines; dorsal spines 1st and 2nd longer than the longest dorsal soft rays. Cheek with a broad band of small scales from below eye to slightly below corner of the mouth; 2-3 scales dorsally on opercle.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Juveniles in coastal waters along reef edges on sand or rubble, or open patches on reef. Adults mainly in deep outer reef habitats where they occur in small loose group along sand ridges (Ref. 48636).
