Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 9; Mjukstrålar i ryggfenan (totalt) : 19 - 20; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 18 - 19.
Occur in clear, current-swept terraces of seaward reefs. Observed in loose aggregations 1 or 2 meters above the bottom; juveniles and subadults typical in groups near isolated Pocillopora eydouxi coral heads and when alarmed hide themselves tightly among the branches (Ref. 9710). Benthopelagic (Ref. 58302). Feed on zooplankton and occasionally on algae (Ref. 9710, 48637, 27115, 83665). Relatively uncommon and highly localized (Ref. 1602, 9710). Very popular and hardy aquarium fish. Anterolateral glandular groove with venom gland (Ref. 57406).
