生物學特性     字彙 (例如 epibenthic)

Occurs in clear lagoon and seaward reefs from 0.5 to at least 30 m. Found in pairs or small groups and nests near bases of dead corals, often on clumps of algae. Monogamous (Ref. 52884, 48637). Feeds exclusively on Acropora polyps. Feeding takes place throughout the day becoming less towards the evening (Ref. 46144).

出現於來自 0.5 到至少 30 公尺的清澈的潟湖與臨海礁石。 成對發現了或在死珊瑚的基底附近的小群魚群與巢, 時常在海藻叢上。 一夫一妻的.(參考文獻 52884) 專門捕食 Acropora 水螅體。 進食全天候發生將近晚上變得比較少的。 (參考文獻 46144)

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚

Aggression is used commonly in courtship. Spawning commences when after swimming together in different tufts, the female concentrates on just one and begins to thrust repeatedly and pause. The male follows suit nuzzling the female. The female then drops into the algae and spawns, while the male releases the sperm beside her. The pair then swims back to their territory (Ref. 46144). Monogamous mating is observed as both facultative and social (Ref. 52884).印度-太平洋: 東非南至莫三比克的馬普托 (參考文獻 4421) 而且東至美屬薩摩亞, 北至琉球群島, 南至大堡礁的南方，新加勒多尼亞與東加。 在紅海被 Oxymonacanthus halli 取代了。
