The taillight shiner (Notropis maculatus) is a species of freshwater fish in the cyprinid family.

Their habitat consists of shallow, slow moving pools, rivers, lakes or swamps, usually containing some aquatic plant life.

They have been classified as least concern by the IUCN due to their wide distribution and large populations.

Spawning begins in March, extends into early October and occurs near logs or similar objects.

[4] They have been observed to occasionally practice oral grasping behaviour in order to maintain stationary in flowing water.
