Morphology | Morphometrics
soft rays: 12 - 15;
Vertebrae: 34 - 36. Incomplete lateral line; infraorbital process absent; branched dorsal fin rays 7-8, branched anal fin rays mostly 10-11. Can be distinguished from all other Danio species by the following combinations of characters: a series of short and wide vertical bars or blotches anteriorly on the sides, followed by a horizontal dark P stripe ending at caudal fin base; a short, incomplete lateral line; and barbels absent . The most similar species, D. shanensis, has the lateral line complete or nearly complete (23-32 versus 7017 pored scales), a shorter distance between the cleithral spot and the first vertical bar (2-3 scales versus 0.5-1.0 scale), and deep and thin vertical bars instead of short and wide vertical bars or blotches anteriorly on the sides.
Found in a mountain stream with clear, fast running water and a cobble substrate (Ref. 36341).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00175 - 0.01195), b=3.15 (2.92 - 3.38), 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.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
