Juveniles are common in coastal waters and are known to find their way to estuaries and coastal lagoons. Growth in juveniles is moderate (30-40 cm in 4 years). Feed on microscopic or filamentous algae and small juveniles of planktonic organisms (Ref. 9626). Juveniles and adults both feed on algae and detritus (Ref. 26987, 33). Herbivore (Ref. 40102).
