Tidal habitat
Tidal flats, creeks and mangrove areas are reported settings. FishBase classifies it as non-migratory. Its occurrence across coastal salinities should not be confused with a requirement for exclusively freshwater conditions.

Life history
This is not a seasonal killifish: its life cycle is not described as the annual, temporary-pool pattern associated with some other killifishes. The source also notes difficulty maintaining it in aquaria. A common name containing “killifish” therefore says little by itself about either its habitat or care requirements.
