Adults are found inshore in schools, frequently entering brackish lagoons and freshwater (Ref. 30578). They migrate occasionally tending to move northward in summer-time as temperatures rise. Females are larger than males (Ref. 59043). Adults feed mainly on benthic diatoms, epiphytic algae, small invertebrates and detritus (Ref. 2804), juveniles only feed on zooplankton (Ref. 59043). Oviparous (Ref. 205). Reproduction occurs in the sea during winter (Ref. 30578). Eggs and larvae pelagic. Utilized as a food fish (Ref. 4645).
Juveniles around 2.0 cm SL move to coastal lagoons and estuaries in April-June and return to sea in summer (Ref. 59043).
