Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 12 - 13; Mjukstrålar i ryggfenan (totalt) : 18 - 21; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 16 - 18.

Usually solitary or in pairs in coral-rich areas of reef flats, lagoons, and seaward reefs to a depth of over 15 m. Juveniles inshore. In pairs or traveling in small groups (Ref. 48636). Feed on octocorallian and scleractinian coral polyps. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205). Easy to maintain in the aquarium. Minimum depth reported taken from Ref. 30874.

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