Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 2; Raggi dorsali molli (totale) : 31 - 35; Spine anali: 0; Raggi anali molli: 29 - 32. Ventral rudiment absent; bristles on caudal peduncle of males longer than others on body (Ref. 37816).

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).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

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).
