Espinhos dorsais (total) : 7; Raios dorsais moles (total) : 23 - 26; Espinhos anais: 1; Raios anais moles: 23 - 26; Vértebras: 26. Light bluish gray in life, shading posteriorly to black; snout blackish; operculum with iridescent blue markings. Chin with a low fleshy protuberance, narrowing posteriorly to a low longitudinal fold. Caudal fin lobes blackish to dark reddish, broad centro-posterior region of fin whitish to yellowish; 1st dorsal fin dull orangish; 2nd dorsal and anal fins largely blackish; pectoral base with an orange to orange-red bar edged in blue. Juveniles with an oval black spot larger than eye at lower base of caudal fin. Body shape (shape guide): elongated; Cross section: compressed.
Adults occur in outer reef slopes, also inhabits lagoons and bays. Usually in pairs as adults and in small aggregations as juveniles, Ref. 48637. Monogamous (Ref. 52884). They feed on zooplankton while hovering 1 to 2 m above the bottom. They swim away from danger rather than retreat to its burrow.
