The Cherry Darter is found in the upper Caney Fork System of the Cumberland River in Tennessee. They live in rocky pools and riffles with bedrock substrate. As the common name suggests, breeding male Cherry Darters have bright red coloration on their side, belly, and fins. Like many members of the Snubnose Darter group, Cherry Darters have a bright red dot in the first membrane of their first dorsal fin and a blunt snout. Their scientific name honors Dr. David Etnier, a renowned ichthyologist at the University of Tennessee.
