Found in rivers and river mouths, coastal swamps, estuaries and other shallow parts of Lake Tanganyika (Ref. 47311). Occurs in small groups near river banks; found in slow flowing and stagnant water of river mouths and deltas near lakes (Ref. 36901). Feeds on algae, fish scales, termites, chironomid larvae, prawns and copepods (Ref. 43507). Not a seasonal killifish; easy to maintain in the aquarium (Ref. 27139). Eggs have development time of 14 days in captivity; sexual maturity reached at age of 5 months (Ref. 47311).
