Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 4420); common length : 30.0 cm TL male/unsexed; (Ref. 3109)
Inhabits reef channels or along slopes that are subject to strong currents (Ref. 48637). Occur in current-swept seaward coral reefs. Usually form aggregations and feed on zooplankton as well as sponges (Ref. 9770). Juveniles associated with isolated patches of rubble or crevices with proper-sized shelter holes (Ref. 1602). Oviparous (Ref. 205). Form large schools to feed on zooplankton (Ref. 48637). Also taken by drive-in nets (Ref. 9770). Marketed fresh or dried-salted. Minimum depth reported taken from Ref. 30874. Popular aquarium fish (Ref. 37816).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Distinct pairing (Ref. 205). Only females tend the eggs but both parents keep guard (Ref. 116451).
