Barrens Darter (Etheostoma forbesi)


The Barrens Darter is found in the Barrens region of the upper Caney Fork System in middle Tennessee. They live primarily in pools and riffles with slab-rock and gravel substrate. Like other members of the subgenus Catonotus, this species spawns on the underside of flat rocks. In this group, males of some species have a golden edge on their second dorsal fin that is hypothesized to serve as an “egg-mimic” to attract females for spawning.
