Prefers surface layer of smaller and more quiet waters which usually are shallow and which may be subject to desiccation from time to time; also found in fast flowing waters; often seen in large accumulations; feeds on small terrestrial insects, water insects and their larvae, and other animals like crustacean and others which they are able to swallow; deposit eggs between plants and roots in shallow water or at margin of waters; young need 8-10 days to hatch (Ref. 27292). Not a seasonal killifish (Ref. 27139).
