Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 10; Anal spines: 0; Anal soft rays: 15 - 17. Incomplete lateral line, perforating 9-10 scales; without infraorbital process, with 7 branched dorsal-fin rays and modally 13 branched anal-fin ray. Can be distinguished from all other Danio species by the combination of having two pairs of long barbels, and lacking horizontal dark stripes posteriorly along the sides. The most similar species, D. albolineatus s. str., has a deeper body, possesses two horizontal dark stripes along the posterior part of body, longer rostral barbels (extending beyond instead of not reaching to the posterior margin or orbit), and more vertical scale series along the side (29-30 versus 28) (Ref. 37789). Possesses pink stripe in anal and pelvic fins; white upper and lower margin in caudal (Ref. 43281).
Inhabits small streams with relatively cold, running water under forest cover, associated with springs and waterfalls (Ref. 37789). Occurs usually in springs and small creeks, but also found in the Mekong main river (Ref. 43281).

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=0.00501 (0.00210 - 0.01198), b=3.15 (2.93 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.0 ±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).
