Biology     Glossary (e.g. epibenthic)

Occurs in lagoon and seaward reefs. Feeds exclusively on the polyps of the tubular Acropora corals. Swims in pairs and are territorial. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
