背棘 (總數) : 8 - 11; 背的軟條 (總數) : 11 - 15; 臀棘: 0; 臀鰭軟條: 6 - 9. Differs from all members of the Etheostoma spectabile complex except E. tecumsehi in having orange belly color confluent with the anterior orange interspaces in breeding males and in having the alternating orange and blue transverse bars prominent along the entire length of the body (versus limited to posterior half) (Ref. 47261).
有別於除了 E. tecumsehi 以外的 橙胸鏢鱸〔Etheostoma spectabile〕 複合體的所有成員有 , 橘色的腹面顏色與在繁殖期的雄性中的前面橘色的間隙匯合而且有交互的橘色而藍色的橫跨橫帶突出的沿著整個的體長 (對僅限於的後半段).(參考文獻 47261)
Attains its greatest abundance in small (1-2 m wide) to medium (3-5 m wide) upland gravel and cobble streams where it is found mainly in moderately-flowing to swift shallow riffles and runs (Ref. 47261). Adults and juveniles are encountered in pools over gravel and bedrock but not as common there unless the pool is in or near a spring (Ref. 47261).
達到它最大的豐度在小的 (1-2 公尺寬) 對中等的 (3-5 公尺寬) 丘陵地礫石與圓石溪流在那裡它被主要發現於水流速度中等到迅急的水淺急流與小水流.(參考文獻 47261) 成魚與稚魚在礫石與岩床上的水池被見到但是不當普遍在那裡除非水池在泉水裡或附近.(參考文獻 47261)
