Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 10; Raggi dorsali molli (totale) : 13; Spine anali: 3; Raggi anali molli: 7.
Body shape (shape guide): elongated; Cross section: oval.
Adults inhabit steep outer reef slopes exposed to strong currents where it lives in large gorgonians and black corals (Ref. 3921). Benthic (Ref. 58302). Common below 25 m (Ref. 90102). Adults feed on small benthic or planktonic crustaceans. The suggestion that this species lays demersal eggs (Ref. 3921) is questionable. Pelagic spawning has been observed for this species from field observations (Ref. 26305). Monogamous (Ref. 52884) and strongly territorial (Ref. 26305). Uncommon to rare in most areas (Ref. 9710).

Distinct pairing (Ref. 52884). Actual spawning lasts about 1-2 seconds while ascending a distance of less than 0.25 m (Ref. 26305). Courtship and spawning behavior is similar to that described for other species: 1) courtship commences just before or after sunset with spawning after sunset; 2) successive courtship and spawning by the male in social groups containing one or more females; 3) courtship and spawning at a site common to both male and female or at a site located within the female's home area; 4) pelagic spawning with a rapid but relatively short ascent into the water column by both male and female; 5) return of the male and female to resident corals afte spawning.
Monogamous mating is observed as both facultative and social (Ref. 52884).
