Spring Pygmy Sunfish
This tiny sunfish survives in clear vegetated springs of the Tennessee Valley, where groundwater quantity and aquatic plants matter more than open water.

Artwork inspired by Clara Weaver Parrish
Breeding males darken dramatically and flash iridescent blue-green bars; females and nonbreeding fish are subtle among stems. The species lives close to dense submerged vegetation, feeding and spawning within a few centimeters of cover.
Its known range has repeatedly contracted as springs were ditched, impounded, polluted, or dewatered. Do not dip-net or enter occupied spring runs: even careful feet can crush vegetation holding eggs and fish.

Good to know
Stay out of occupied springs and never collect, seine, or move vegetation. Even careful wading can crush the aquatic plants that shelter eggs and breeding fish.
