Range Extent Comments
Native range encompasses the Atlantic Slope from the St. Lawrence River drainage, Quebec, to Lake Okeechobee, Florida; Gulf drainages west to the Brazos River, Texas; Mississippi River and Great Lakes basins north to Nebraska, Wisconsin, Michigan, and southern Ontario; absent in Appalachian uplands (Lee et al. 1980, Page and Burr 2011). The species has been introduced in various localities in the western United States (e.g., Washington, California, Colorado) and eastern United States.

Subspecies americanus: Atlantic Slope drainages south to southern Georgia. Subspecies vermiculatus: remainder of range, with intergradation in most of Florida and in Gulf Slope drainages west to the Pascagoula River.
Occurrences Comments
This species is represented by a very large number of occurrences (subpopulations) (e.g., see map in Lee et al. 1980).
Threat Impact Comments
No major threats are known.
Ecology & Habitat

Habitat

Habitat includes small, quiet, heavily vegetated waters: pools and backwaters of streams, canals, ponds, and bays of small lakes; this fish more often occurs in streams than in lakes. Eggs sink and stick to bottom and vegetation. Adults may move upstream to spawn in flooded stream margins or marshes where vegetation is abundant (Scott and Crossman 1973).

Ecology

Not territorial (Lee et al. 1980).

Reproduction

Spawns mainly in spring but also sometimes in fall. Eggs hatch in about 11-15 days. Sexually mature by age 2.
