Dorsale stekels (totaal) : 12; Dorsale zachte stralen (totaal) : 14 - 16; Anale stekels: 2; Anale zachte stralen: 12 - 14. Color variable according to ecological and behavioral conditions: basically body whitish with snout, interorbital and forehead greenish; black bar on anterior and a fainter one on posterior part of the body; blackish scale margins; pelvic fins mostly black; pectorals transparent with a spot on its base. Margins of preorbital, suborbital, and preoperculum finely serrated (Ref. 2746). Body depth 1.4-1.6 in SL (Ref. 90102).
Adults occur in outer lagoon and seaward reefs. They inhabit branching coral heads, particularly Pocillopora eydouxi. Form schools, often in silty habitats (Ref. 48636). Male prepares a nest by cleaning with its mouth a rock or coral surface where the female will attach the eggs (Ref. 5503). Oviparous, distinct pairing during breeding (Ref. 205). Diurnal species (Ref. 54980; 113699).

Benthic spawner. Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Also Ref. 103751.
