唇隨著年齡變厚。 (參考文獻 1623) 顏色大幅改變隨著年齡與性別.(參考文獻 48636) 稚魚與亞成魚前面地幾乎白色與突然深綠色與黑色的在後部地; 在大約 8 公分下面的那些有一個慢慢地隨著成長褪色的鮮黃色的尾部。 (參考文獻 1602) 色彩鮮豔的粉紅色與藍色的臉斑紋用成長環繞稚魚的眼睛四周傳佈幾乎覆蓋大的成魚的整個頭。 (參考文獻 1602)
Found in subtidal reef flats and lagoon and seaward reefs. Juveniles occur inshore, found among branching corals while adults found in areas of mixed sand, rubble, and coral (Ref. 9710). Large adults in deeper water (Ref. 48636). Maximum length beyond 45 cm TL is unlikely, with largest measured individual at 37 cm TL (Ref, Feeds mainly on small invertebrates, especially crustaceans, polychaete worms, mollusks and brittle stars (Ref. 9823). Diet changing from primarily demersal planktonic crustaceans to hard-shelled invertebrates with growth (Ref. 37816). Minimum depth reported taken from Ref. 128797.
發現於亞潮間帶的礁石平臺與潟湖與臨海礁石了。 稚魚出現沿海地區, 發現於樹枝狀珊瑚中了雖然成魚發現於混合沙子，碎石與珊瑚的區域。 (參考文獻 9710) 大的成魚在較深的水域中。 (參考文獻 48636) 主要吃小型無脊椎動物, 尤其甲殼動物, 多毛類的蠕蟲，軟體動物與海星.(參考文獻 9823) 從主要底棲浮游性甲殼動物到具有硬殼的無脊椎動物隨著成長改變食性。 (參考文獻 37816)
