有 8-10 深色的﹐相當不規則, 縱帶略微比間隙寬; 在尾鰭基底的一條完全的黑色橫帶; 活著時，一個黑色的斑點在前面的背鰭基底跟隨著一橘色的對紅色的斑點; 一個瘦長的黑色斑塊; 一條不完全的側線頂多達到垂直的臀鰭起源; 在上嘴唇中的沒有中央的切口.(參考文獻 27732) 尾鰭邊緣微凹的;(參考文獻 39226) 尾柄長度 6.5-7.5 標準體長比率, 倍長的深度 0.8-1.2.(參考文獻 43281) 背鰭起點上方或在腹鰭嵌入之前; 頭頂有斑點的; 鱗片在腹面上在胸鰭頂端之前不存在。 (參考文獻 12693)

Occurs in shallow riffles in small streams with fast flowing water over pebbled bottom. It probably feeds on insect larvae and small amounts of algae (Ref. 12693). A female 7.84 cm SL with ovulae 1.0-1.2 mm in diameter (Ref. 39226).

出現於在小的溪流淺灘急流底部為小圓石且水流快速的地方。它可能吃昆蟲幼生與少量的藻類。 (參考文獻 12693) 一條母魚 7.84 cm SL 有卵 1.0-1.2 mm 直徑。 (參考文獻 39226)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00692 (0.00310 - 0.01545), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

營養階層 (Ref. 69278): 2.6 ±0.28 se; based on food items.

回復力 (Ref. 120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
