The video below, taken in late June by metro Atlanta resident Mark Rosseter, shows yellowfin shiners spawning in a Decatur creek over a gravel nest made by bluehead chubs or bluefin stonerollers.

The bluehead chubs are the bigger fish glimpsed in the video. The bluefin stonerollers are also larger but have a black band on their dorsal fin.

Yellowfins — the smaller, flashier minnows — are “nest associates” that primarily spawn over nests built by bluehead chubs. All of these fishes are native to Georgia.

Which begs the question, what’s going on in creeks near you?
