Occurs in coastal zones, also found in oasis pools with hypersaline to fresh water (Ref. 3788). Forms schools. Chiefly a herbivorous species (Ref. 13530). Spawn in areas where roots of hyacinth or other floating plants abound (Ref. 44327). Not a seasonal killifish. Very difficult to maintain in aquarium (Ref. 27139).
