Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); texanus: Named after the type of locality, of Texas (Ref. 10294). More on author: Girard.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate; 38°N - 34°N
North America: lowlands in Great Lakes, Hudson Bay (Red River) and Mississippi River basins from Michigan, Wisconsin and Minnesota in the USA south to Gulf; Gulf Slope drainages from Suwannee River in Georgia and Florida in the USA to Nueces River in Texas, USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.6 cm TL male/unsexed; (Ref. 5723); common length : 4.4 cm TL male/unsexed; (Ref. 12193); max. reported age: 3.00 years (Ref. 12193)
Inhabits sandy runs and pools of creeks and small to medium rivers. Occurs usually in clear water. Often found near vegetation in the north part of range (Ref. 5723, 10294). Feeds on filamentous algae and detritus, in addition to the expected small invertebrates (Ref. 10294).

Bayesian length-weight: a=0.00724 (0.00429 - 0.01223), b=3.11 (2.97 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.5 ±0.19 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tmax=3).
Vulnerability (Ref. 59153
