Description

The blackspotted topminnow (Fundulus olivaceus) is a small killifish of the family Fundulidae from central and southeastern North America. The species has a slender, silvery body with a broad, black lengthwise stripe and numerous small black spots on the back, and an upward-pointing mouth; it reaches about 8 cm. It stays near the surface of quiet to flowing water, usually along the margins of clear, sandy to gravelly headwaters, creeks and small rivers. As a surface hunter it feeds mainly on insects. Owing to its small size the species has no fishery value, but it is sometimes used as bait.
