Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 9; Rückenflossenweichstrahlen (insgesamt): 28-30; Afterflossenstacheln 3; Afterflossenweichstrahlen: 23 - 26. Blue with a white chest (Ref. 3145).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Inhabits shallow, clear coastal and island coral reefs (Ref. 9710). Usually found on reef flats and along upper seaward slopes (Ref. 9710). May occur singly or in large feeding aggregations. Monogamous (Ref. 52884). Feeds on benthic algae; on small, sparsely scattered algae and small growths in crevices (Ref. 28026). Caught with nets (Ref. 30573). Marketed fresh.

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Paired spawning (Ref. 240). Monogamous mating is observed as both obligate and social (Ref. 52884).
