生物學特性     字彙 (例如 epibenthic)

Juveniles are encountered under ledges, or in holes of outer lagoon patch reefs or semi-protected areas of exposed channels and outer reef flats. Subadults move to reef front holes and surge channels. Large adults inhabit ledges and caves in areas of rich coral growth on clear lagoon, channel, or seaward reefs (Ref. 6113). Benthopelagic (Ref. 58302). Feed on sponges and other encrusting organisms (Ref. 6113); also on tunicates. Form pairs. Young and adults may clean much larger fishes such as sunfish (Ref. 48636). Frequently exported through the aquarium trade. Juveniles are distinguished by a white dorsal-fin margin (Ref. 48391).

稚魚被見到岩架下, 或在裸露峽道的潟湖外部礁坪或半遮蔽區域與外礁平臺的洞中。 亞成魚移動到礁前面洞與洶湧的峽道。 大的成魚在清澈的潟湖,峽道或臨海礁石上的豐富珊瑚成長的區域中居住於岩架與洞穴。 吃海綿與其他的硬殼生物;(參考文獻 6113) 也吃被囊類。 成對。 幼魚與成魚可能清理大很多的魚例如翻車魚。 (參考文獻 48636) 時常經由水族貿易輸出了。 稚魚被藉著白色的背鰭邊緣區別。 (參考文獻 48391)
