Comments: Inhabits lagoons, salt marshes, swamps, estuaries and freshwaters.  Euryhaline, occurring in water bodies with salinities ranging from freshwater to 57 ppt (Ref. 59043).  Occurs in lowland water with little current.  Spawns from April  to September.   Is an egg-laying carnivorous fish which is used for mosquito control (Ref. 26100).  This short-lived species is now threatened throughout its entire range because of habitat destruction and because of the introduction of <i>Gambusia affinis</i> (Ref. 3788).  Not a seasonal killifish.  Is easy to maintain in the aquarium (Ref. 27139).
