This is a small, plain fish, with a snout that slightly overhangs the lower jaw: the dorsal fin originates in front of the pelvic fin, the mouth is small and the scales are large (37-40 along the lateral line). It lacks maxillary barbels. For further information, refer to McPhail (2008).

BC Distribution and Notes The biology of this little fish is a mystery. It is especially abundant in the lower Fraser Valley and headwater ponds and small lakes in the Prince George area. In between it is exceedingly rare. In the lower Fraser Valley it appears to migrate to and from the main river; however, its movements are largely uncharted. All we know is that, seasonally, it turns up in large numbers at some sites and then disappears. The populations in the Esker Provincial Park appear to be extinct. Probably victims of an exotic species (brook trout) introduced to create a recreational fishery. Source: Information provided by Don McPhail for E-Fauna BC.
