Freshwater; demersal. Temperate; 0°C - 33°C (Ref. 35682); 50°N - 31°N
North America: Great Lakes, Hudson Bay (Red River) and Mississippi River basins from southern Quebec to southern Manitoba, Canada and south to Louisiana, USA; Atlantic Slope from St. Lawrence River in Quebec to Roanoke River in USA; Gulf Slope from Mobile Bay drainage in Alabama to Mississippi River, USA.

Maturity: Lm ?  range ? - ? cm
Max length : 11.0 cm TL male/unsexed; (Ref. 5723); common length : 6.5 cm TL male/unsexed; (Ref. 12193); max. reported age: 5 years (Ref. 12193)
Occurs almost anywhere in its range but most common in clear rocky streams (Ref. 3814, 10294); also inhabits large rivers, reservoirs and glacial lakes to the north. Feeds on algae, detritus, entomostraca, and immature insects, especially midge larvae and pupae (Ref. 10294).

Bayesian length-weight: a=0.00692 (0.00383 - 0.01250), b=3.21 (3.05 - 3.37), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.7 ±0.1 se; based on diet studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=5).
Vulnerability (Ref. 59153
