Adults occur in clear lagoon and seaward reefs from 0.5 to at least 30 m. They go around in pairs or small groups and nest near bases of dead corals, often on clumps of algae. Monogamous (Ref. 52884, 48637). They feed exclusively on Acropora polyps. Feeding takes place throughout the day becoming less towards the evening (Ref. 46144).
ライフサイクルと交尾行動
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
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).
