Description
The Blackfin Darter is a small, bottom-dwelling freshwater fish native to the southeastern United States. It is known for its cryptic coloration, which helps it blend into its rocky or gravelly stream habitat, and its distinctive black-tipped fins, especially prominent in breeding males. This species requires excellent water quality, strong oxygenation, and a diet of live or frozen invertebrates.
