Etymology: Etheostoma: Greek, etheo = to strain + Greek, stoma = mouth; Rafinesque said "various mouths", but Jordan and Evermann suggest the name might have been intended as "Heterostoma (Ref. 45335); asprigene: asprigene meaning rough cheek (referring to the fully scaled cheek and opercle) (Ref. 79012).

Maturity: Lm ?  range ? - ? cm
Max length : 7.1 cm TL mannelijk / geslacht onbekend; (Ref. 5723); common length : 5.0 cm TL mannelijk / geslacht onbekend; (Ref. 12193); max. gerapporteerde leeftijd: 3.00 Jaren (Ref. 12193)
Inhabits sluggish riffles over rocks or debris in small to large rivers; also lowland lakes (Ref. 5723), creeks, swamps and reservoirs (Ref. 10294). Feeds mainly on midge and blackfly larvae (Diptera); small fish consumes more microcrustaceans (Ref. 79012).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (tmax=3).
Fishing Vulnerability (Ref.
