Short description Identification keys | Morphology | Morphometrics

Differs from all of its congeners by the following combination of characters: lateral line incomplete to absent, perforating 0-6 scales; 29-32 scales along normal course of lateral line; a conspicuous black (bluish black in life) lateral stripe from tip of snout to extremity of median caudal rays; body slender, its depth 4.4-4.8 times in SL (4.0-5.1); caudal peduncle slender than all other Rasbora, its depth 2.3-2.8 times in its length (2.3-3.3); and long and pointed dorsal and anal fins (Ref. 26753).

Common in forest streams and clear black water (Ref. 56749). Maximum length 15 cm TL in Ref. 2060.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00390 - 0.02036), b=3.02 (2.82 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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