In vegetated sloughs, ponds, lakes, and sluggish streams; enters brackish water. 6.5 cm max TL (Ref. 5723). In Guinness Book of Records as the fish with the fewest eggs (20 eggs are spawned over a period of several days) (Ref. 6472). Feeds on worms, crustaceans, insects and plant matter (Ref. 7020). Not a seasonal killifish. Is easy to maintain in the aquarium (Ref. 27139).
Life cycle and mating behavior
Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves
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).
