Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 3; Raggi dorsali molli (totale) : 33 - 36; Spine anali: 0; Raggi anali molli: 28 - 31.
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).
