Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); rupestris: Specific epithet is an adjective meaning to live among rocks, referring to the bedrock and rubble pools which the species lives.

Max length : 7.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 58354)
背的軟條 (總數) : 8; 臀鰭軟條: 7 - 9. Distinguished from its congeners by the following combination of characters: black-stripe around snout and along side to caudal-fin base, followed by a small black spot; black stripe along side connects a series of crescents, on at the posterior edge of each lateral-line scale; lateral line usually complete; body slender, fairly compressed with notably arched nape; dorsal-fin origin over to slightly behind pelvic-fin origin; small mouth, nearly terminal; predorsal scales 10-14, usually 11-13; gill rakers 8-11, rarely 7; peritoneum black (Ref. 58354).
Body shape (shape guide): elongated; Cross section: oval.
與它的同類區分了藉由跟隨組合特徵: 黑色的-吻的周圍斑紋而且沿著旁的到尾鰭基底, 跟隨著一個小的黑色斑點; 黑色的斑紋沿著側邊連接一系列的新月, 在每個側線鱗片的後緣之上; 側線通常完成; 身體細長的, 非常扁長形的具有特別弓形的後頸; 背鰭起點到之上些微地在腹鰭起點後面; 小的嘴, 幾乎位於末端的; 前背的鱗片 10-14, 通常 11-13; 鰓耙 8-11, 很少地 7; 腹膜黑色.(參考文獻 58354)
Occurs usually near emergent vegetation in bedrock pools of headwaters, creeks and small rivers. These areas are prone to intermittency and harbor relatively few other fishes. This species appear to be extreme in its ability to tolerate stagnant conditions resulting from low water (Ref. 58354). Feeds on midge larvae, chydorid cladocerans, water mites, copepods and small mayflies (Ref. 10294).
在河川源頭,小溪與小河的岩床水池中通常生活在靠近突出的植物附近。 這些區域是有 intermittency 的傾向與港灣相當少見的其他魚。 這種狀似它的能力的極端容忍起因於落潮的污濁的環境。 (參考文獻 58354) 吃蚊仔魚， chydorid 水蚤，水小蝨，橈腳類的動物與小的孚游類。 (參考文獻 10294)
