Comments: Inhabits lagoons, tidal canals and small, shallow coastal streams, with water fresh to hypersaline and with silt bottom.  Omnivorous, feeding on zooplankton, small insects, vegetal matter and detritus.  Freshwater populations are threatened due to the introduction of <i>Gambusia holbrooki</i> and <i>Fundulus heteroclitus</i> (Ref. 59043).
