Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 12 - ? cm
Max length : 22.0 cm SL male/unsexed; (Ref. 5316)
Occurs in relatively shallow (25-150 cm), still to slow-flowing water (Ref. 6028). Inhabits freshwater streams, rivers and estuaries. Juveniles and subadults are usually found in estuaries while adults are found upstream in freshwater areas. Feeds 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)
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Female deposits eggs on the ventral surface of the male trunk's or tail , where they are incubated for several weeks. Males may be brooding at 12 cm SL (Ref. 5316).
