Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); chalybaeus: Notropis=ridged or keeled back, and chalybaeus=iron colored (referring to the lateral band) (Ref. 79012).

Maturity: Lm ?  range ? - ? cm
Max length : 6.5 cm TL male/unsexed; (Ref. 5723); common length : 5.0 cm TL male/unsexed; (Ref. 12193)
North America: USA.
Occurs in clear, vegetated, sand-bottomed pools and slow runs of creeks and small rivers (Ref. 5723). Feeds mainly on small crustaceans (amphipods, cladocerans, and ostracods), aquatic insects (caddisfly, midge, and mayfly larvae, and corixids), and terrestrial insects (ants), and filamentous algae (Ref. 79012).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00286 - 0.01212), b=3.09 (2.91 - 3.27), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.9 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
