Banded killifish are a schooling fish that occurs in the shallow areas of lakes and slow moving rivers. It is commonly found in sandy areas with aquatic vegetation, and can tolerate slightly brackish waters. The banded killifish diet consist of aquatic insects, mollusks and vegetation. The banded killifish spawns during the mid summer months, usually June - July, in shallow, weedy areas. The eggs are released are highly adhesive attaching to the substrate and vegetation. The spawning adults provide no parental care to the eggs or young.
