生物学特性     字汇 (例如 epibenthic)

Inhabits clear lagoon and seaward reef slopes (Ref. 9710, 48637). Benthopelagic (Ref. 58302). Usually seen in large schools (Ref. 90102). Mainly diurnal, it feeds on zooplankton such as crab larvae, arrow worms, pelagic tunicates, and occasionally filamentous red algae. The species is never poisonous (Ref. 4795).

栖息于清澈的舄湖与临海礁石斜坡。 (参考文献 9710,48637) 浅水型。 主要日行性, 它吃浮游动物例如螃蟹幼虫, 箭蠕虫,大洋性被囊类与偶然丝状的红藻。 此鱼种从不是有毒的。 (参考文献 4795)
