Taillight Shiner (Notropis maculatus)

Description: 

The Taillight Shiner is widespread in lowland Gulf and Atlantic coast drainages from Louisiana to North Carolina, including the Mobile Basin in Alabama and Tennessee, and also in the Mississippi Embayment northward to southern Illinois. They are found in swamps and backwaters of small to large rivers. As the common name suggests, Taillight Shiners have a light depigmented area behind the black spot at the base of the tail.
