Habitat

The redband darter inhabits shallow pools with rocky substrates as well as streams and springs. These springs, which are usually of moderate gradient and have limestone bedrock, rubble, gravel, and silt substrates. Such streams are very productive and usually have growths of aquatic mosses, filamentous algae, and/or watercress. Spawning occurs during March and April. During this time, individuals are common in gravel riffles, which may be the spawning area.Etnier, David A., and Wayne C. Starnes. ''The Fishes of Tennessee''.
