Description

The banded killifish is a slender killifish of the family Fundulidae reaching about 13 cm. The silvery body has a flat back and an upturned mouth, a build suited to hunting just below the water surface, and bears numerous narrow, dark cross-bars along the flank (especially in the female). The species is native to the fresh water of eastern North America and lives in schools in shallow, vegetated water of lakes, ponds and slow-flowing rivers; it tolerates brackish water. It eats insect larvae, especially mosquito larvae, zooplankton and small snails. In spring and summer the sticky, threaded eggs attach to water plants. It is an important prey fish and mosquito controller.
