Description
The Rio Grande Darter is a small, bottom-dwelling freshwater fish native to the Rio Grande basin. It typically exhibits mottled brown coloration with reddish fins, blending well with its preferred rocky or gravel stream habitats. These darters are insectivores, feeding on small invertebrates found in clear, flowing water.
