Seminole Killifish
Fundulus seminolis
The Seminole Killifish is a Florida freshwater native that patrols shallow lake edges, canals, and slow rivers for insects and small prey.
Seminole Killifish live in vegetated margins of lakes, rivers, ponds, and canals across much of the Florida peninsula. They tolerate warm water and often stay near the surface.
Males develop brighter blue-green color during breeding. Shoreline plants and clean shallow water provide feeding and spawning habitat.
