Found in large
rivers and estuaries. Occurs in high estuary (freshwater
tidal zone) as juveniles, moving to brackish water as
sub-adults, and finally as adults to river mouths and
inshore areas. Longevity given as 10 years but appears too
low. Feeds on snails, other mollusks and plants. Reared for
consumption in Thailand, Cambodia and Vietnam; excellent
food fish with very white fine grained sweet flesh.
