生物學特性     字彙 (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).

棲息於清澈的潟湖與臨海礁石斜坡。 (參考文獻 9710) 淺水型。 主要日行性, 它吃浮游動物例如螃蟹幼蟲, 箭蠕蟲,大洋性被囊類與偶然絲狀的紅藻。 此魚種從不是有毒的。 (參考文獻 4795) 最小深度報告取自參考文獻 1602.
