Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.0 cm SL male/unsexed; (Ref. 27732)
Numerous conspicuous rows of pores on the head; an incomplete lateral line perforating about 6 scales; a dark crescent-shaped mark at the base of each scale; a dark blotch at the base of the caudal fin, one at the tip of the dorsal fin and one along the anterior margin of the anal fin (Ref. 27732).
Lives in hill stream (Ref. 57235). Usually found in clear, slow-flowing water (Ref. 43281). Apparently a widely distributed species but overlooked because of its small size (Ref. 27732).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00516 - 0.02330), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 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).
