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).

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).南美洲: 委內瑞拉全部沿著在阿根廷的岸邊到拉布拉塔河。 在波多黎各 (參考文獻 26938) 與馬提尼克島引入。 (參考文獻 48621)
