Spines stout and venomous. Preopercular angle 101°-111°. Cheeks fully covered with strong scales. Midline of thorax scaled; scaled pelvic ridges may interrupt scale row pattern. Low rim of anterior nostril expanded posteriorly into a short, broad triangular flap.

Occurs in shallow, coral-rich areas of clear lagoons and seaward reefs. Individuals up to 7 cm SL forms large schools in shallows, lagoons and outer reef flats, particularly in areas dominated by luxurious growths of Acropora. Adults occur in pairs. Juveniles feed on filamentous algae, adults on algae, tunicates, and sponges (Ref. 9813, 48637). Can inflict painful stings (Ref. 4690).
