Identification
The body is relatively robust with a blunt snout and a series of dark blotches along the back and sides. Breeding males show a red band across the first dorsal fin, turquoise fin details and green on the chin. Closely related darters require careful comparison of the extent and placement of color.
Habitat and Feeding
Coosa Darter occupies rocky pools and riffles. Midge and blackfly larvae are among the documented insect foods, with other small aquatic animals also eaten. The Coosa drainage is a key identification clue, though related species replace it in parts of the upper system.
Spawning
Eggs are placed individually in crevices in rock or wood. Central Coosa observations describe breeding from mid-March to mid-May, with an April peak. A crevice-spawning strategy makes small spaces within submerged structure relevant even when the stream looks broadly open and rocky.
Color Placement Matters
A red dorsal fin is not enough by itself. Photograph the entire fin and retain the tributary name when comparing Coosa and related darters.
