Juveniles with a deep brown patch straddling the lateral line; the spot becoming obscured with increase in size. Stout, venomous spines not so pungent. Preopercular angle 87°-105°. Strong scales fully cover the cheeks. Midline of thorax scaled but not pelvic ridges.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Occurs in clear lagoons and seaward reefs. Juveniles live in schools of up to about 50 fish with pairing commencing as small as 15 cm, but fish may still be schooling at 22 cm SL; older fish live in pairs. Feeds on benthic algae (Ref. 9813). Adults on deep coastal reefs, juveniles in shallow estuaries (Ref. 48637).
