生物学特性     字汇 (例如 epibenthic)

Juveniles occur in clear, shallow lagoon reefs at depths as little as 1 m; adults rarely seen in less than 25 m, encountered off outer reef drop-offs in small schools (Ref. 30573, 48637). Benthopelagic (Ref. 58302). Feeds on large zooplankton during the day and shelter within the reef during the night; also benthic algae (Ref. 30573, 48637).

稚鱼出现在清澈的, 水浅的舄湖礁在深度浅到 1 公尺; 成鱼很少在被见到外海的外围礁石海峭壁的少于 25 公尺见到形成小群鱼群。 吃大的浮游动物在白天期间而且躲藏在里面礁夜晚时; 也水底的藻类.(参考文献 30573,48637)
