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

An inshore, surface-dwelling species forming sizeable schools, frequently entering estuaries (Ref. 3723). Uncommon over reefs (Ref. 9710). Omnivorous, feeds on algae and other small animals (Ref. 3723). Caught with 'mandinga' nets in Venezuela, often using lights (Ref. 3723). Edible but not really appreciated (Ref. 3723).
