Rainbow darter

The Rainbow darter is a small, brightly colored freshwater fish native to North America, particularly the United States. It exhibits a striking array of colors, especially in males during the breeding season, including hues of blue, green, yellow, and orange. This fish typically thrives in clear, fast-flowing streams and rivers. Despite its vibrant appearance, the Rainbow darter is not as widely recognized or kept in the aquarium hobby as other more commonly known species, in part due to its specific habitat requirements and conservation concerns in some areas.
