The Blackside Dace is olive green in color with black specks, a silver or red underside, and a single black stripe along its sides. During the breeding season, the male’s stripe becomes a deeper black, the red becomes brighter, and the fins turn a vibrant yellow. In the second and last pictures, the dace are actually using the nests of a different species (the Creek Chub) for spawning.
