Widespread in mildly brackish water in canals and drainage ditches at the edges of swamps, but rarely found in freshwater. Feeds on mosquito larvae and has at times been used for control in ponds and reservoirs (Ref. 35237).
Life cycle and mating behavior
Maturities | Reproduksi, perkembang biakan | Spawnings | Egg(s) | Fecundities | Larva
Males are very active and also approach the females of other Poecilinae. [Females produce 6 - 10 offspring which follow their mother for a few hours after birth, referring to Ref. 35237.] After 28 days gestation, female gives birth to 100 young or more. Sexual maturity is reached after 3-4 months (Ref. 2060).
