背棘 (總數): 12; 背的軟條 (總數): 14-16; 臀棘 2; 臀鰭軟條: 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).
色彩可變的根據生態學而行為的環境: 基本上身體微白色的具有吻，眼間骨與前額呈綠色的; 黑色的橫帶在前面與在身體的較後面的部分上一個比較模糊的; 黑色的鱗片邊緣; 腹鰭大部份黑色; 胸鰭透明具有一個斑點在它的基底。 眶前骨，眶下骨與前鰓蓋骨的邊緣細鋸齒狀的。
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).
出現於潟湖外部與臨海礁石。 棲息於樹枝狀珊瑚頭部, 特別地 Pocillopora eydouxi. 常見於淤泥的棲息地中形成魚群。 (參考文獻 48636) 雄性藉由用嘴清理準備一個巢一塊岩石，或者珊瑚表面母魚將在那裡附上卵.(參考文獻 5503)
