Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); atherinoides: From the words atherina, meaning silverside; and oides, Greek suffix indicating resemblance (Ref. 10294). More on author: Rafinesque.

Length at first maturity / Size / Weight / Age
Maturity: Lm 4.2  range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 5723); common length : 8.6 cm TL male/unsexed; (Ref. 12193); max. reported age: 4 years (Ref. 12193)
North America: widely distributed throughout Canada and south to Virginia and Texas, USA.
Adults inhabit lakes and pools and runs of medium to large rivers. Most common in clear water over sand or gravel. Form schools (Ref. 1998). Move to the surface at dusk to feed on microcrustaceans, midge larvae, and algae; descends to deeper waters at daybreak (Ref. 1998). Are preyed upon by birds (gulls, terns, mergansers, cormorants) and fishes (Ref. 1998). Oviparous (Ref. 205).
