Darters are small, slender fish that are found in freshwater systems, notably in Florida’s springs. Two common darters found in springs are the brown darter and black-banded darter. Their sizes vary, but most darters are between 2 to 3 inches long. Darters possess two dorsal fins and can be seen using its pectoral fins to dart around and out from under vegetation. Some darters are among the most brightly colored fish in North America since breeding males become vibrant and colorful during breeding season.
