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); microperca: From the words micro, meaning small, and perca, perch (Ref. 10294).

Occur in quiet, vegetated lakes, headwaters, creeks and small rivers (Ref. 5723); also found in streams and springs to ponds (Ref. 10294). Usually found over mud and sand (Ref. 5723, 10294). Adults feed on midge larvae, isopods, and microcrustaceans, particularly copepods (Ref. 10294). Eggs are found attached to the substrate unguarded (Ref. 7043).
出现于安静，长满植物的湖泊，河川源头,小溪与小河。 通常发现于泥地与沙地之上。

Eggs are found attached to the substrate unguarded (Ref. 7043). From Ref. 7043, 'a ripe female is courted by males and when ready to spawn positions herself on vegetation, often vertically. A male mounts the female and clasps her back with his enlarged pelvic fins. The two fish vibrate and one to three eggs are deposited on living or dead vegetation.The pair moves to another spot and more eggs are laid.'北美洲: 來自東方的加拿大安大略省與明尼蘇達州的五大湖與密西西比河流域在美國南至俄亥俄州南部，中央的印地安那州與伊利諾州中部; 在美國的密蘇里南部，堪薩斯州東南方的歐薩克山區-歐奇塔河流域, 阿肯色州西北部與俄克拉荷馬州東部。
