The Blacknose dace lives in the demersal, freshwater environment.

The blacknose dace is found in small streams and brooks in Ohio having moderate or high gradients, clear waters, and clean substrates composed of sand, gravel, and cobble. These fish are typically found in fast water where there are overhanging roots or undercut banks. More

CHARACTERISTICS: The deep, rounded body of the blacknose dace is covered with small scales, tapers toward a deep caudal peduncle, and strongly arches downward from the dorsal fin to the tip of the snout. More
