Adults occur usually near vegetation in salt, brackish and fresh water (Ref. 86798). They inhabit hypersaline lagoons and connecting channels. Found on muddy bottoms in turbid waters (Ref. 5217). Omnivorous; consuming organic detritus and algae, as well as microcrustaceans, and dipteran larvae (Ref. 79012). Caught with fine-meshed nets. Very abundant and easily reproduced in captivity. Used as a forage fish in mariculture (Ref. 5217). Not a seasonal killifish. Is easy to maintain in the aquarium (Ref. 27139).
