Adults are found in vegetated sloughs, ponds, lakes, and sluggish streams. They enter brackish water. They feed on worms, crustaceans, insects and plant matter (Ref. 7020). Not a seasonal killifish. Found in the Guinness Book of Records as the fish with the fewest eggs (20 eggs are spawned over a period of several days) (Ref. 6472). Is easy to maintain in the aquarium (Ref. 27139).

Males care for the eggs (Ref. 57667). Lays up to 100 eggs in the aquarium (Ref. 7020). The male does a 'T-dance' with a receptive female and the female lays her eggs over algal-covered rocks where they adhere by their sticky thread. In the laboratory, this was simulated by using a green orlon wool wrapped glass plate - males will continuously guard the eggs on this, fanning with their fins to keep eggs clean and aerated (D. Holdway, pers. com 2006).
