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); olivaceum: olivaceum refers to the coloration (Ref. 10294).

Inhabit rocky pools and nearby riffles of headwaters and creeks (Ref. 5723); also found in streams (Ref. 10294). Often found in very shallow water less than 4 m deep (Ref. 5723). Juveniles feed on midge larvae and microcrustaceans; adults on midge larvae, other immature aquatic insects (mayflies, caddisflies, stoneflies), isopods and amphipods (Ref. 10294). Eggs are found clustered on underside of stone and guarded by males (Ref. 7043).
