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); fonticola: From the Greek etheo=to strain and stoma=mouth; fonticola=fountain dweller (Ref. 79012).

Occur in vegetated springs, pools and runs of effluent rivers (Ref. 5723). Feed primarily on cladocerans, copepods, amphipods, and aquatic insects (Ref. 54633). Spawn throughout the year (Ref. 75081) at 33-day interval (Ref. 31966). Eggs are found attached to the substrate unguarded (Ref. 7043).
