Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 9.0 cm TL mannelijk / geslacht onbekend; (Ref. 30874)
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).
