Adults occur in relatively shallow (25-150 cm), still to slow-flowing water (Ref. 6028). They inhabit freshwater streams, rivers and estuaries. Juveniles and subadults are usually found in estuaries while adults are found upstream in freshwater areas. Adults feed on worms, crustaceans and zooplankton. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Not seen in markets (Ref. 12693)
