簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 臀棘: 0; 臀鰭軟條: 23 - 28. Body somewhat compressed, slender. Snout less than eye diameter; maxilla long, tip pointed, reaching almost to gill opening; gill cover canals of walkeri-type. Anal fin rather long, its origin before midpoint of dorsal fin base. A pair of narrow dark lines along back, from occiput to tail; a silver stripe along flank, less than eye diameter.
身體略微扁長形的, 細長的。 吻少於眼直徑; 顎骨長的, 頂端尖的, 幾乎到鰓裂; walkeri 的鰓蓋運河-類型。 臀鰭相當長的, 背鰭基底的中點前的它的起源。 一對狹窄的黑色線條沿著背面, 從後腦部到尾部; 一條銀色的斑紋沿著側面，少於眼直徑。
Apparently entirely freshwater and presumably schooling. More data needed.
顯然完全淡水而且可能群游。 需要更多的資料。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00234 - 0.01125), b=3.14 (2.97 - 3.31), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
