Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Espinas anales: 0; Radios blandos anales: 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.
Apparently entirely freshwater and presumably schooling. More data needed.

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 (0.00232 - 0.01135), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resiliencia (Ref.
120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
