Taxonomic Comments
This species formerly was included in the genus Phoxinus. Based on patterns of genetic variation, Strange and Mayden (2009) reassigned all North American Phoxinus species to the genus Chrosomus.

This species hybridizes with P. eos (Das and Nelson 1989); hybrids between P. neogaeus and P. eos comprise diploid, triploid, and diploid-triploid mosaic unisexuals; diploids are products of clonal reproduction; hybrids may coexist with P. eos in the absence of P. neogaeus (Dawley et al. 1987). Aclonal reproduction by polyploids also occurs (Copeia 1993:650-660).

Range Extent Comments
Range encompasses Atlantic, Great Lakes, Hudson Bay, upper Mississippi, Missouri, and Peace-Mackenzie river drainages from New Brunswick to Yukon and British Columbia, and south to New York, Wisconsin, Nebraska, and Wyoming, with hybrids south to Colorado (Lee et al. 1980, Page and Burr 2011).
Occurrences Comments
This species is represented by a 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 pools of boggy headwaters, creeks, and small rivers, as well as lakes and ponds; this species is often common in beaver ponds; usually over silt and near vegetation (Lee et al. 1980, Page and Burr 2011). Spawning apparently occurs under logs and debris.

Reproduction

Spawns April to June. Eggs hatch in about 4 days. Sexually mature by age II (Becker 1983).
