Etymology: Schistura: Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic; pH range: 5.8 - 7.0; dH range: 4 - 15. Tropical; 23°C - 28°C (Ref. 13614)

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 8.5 cm SL male/unsexed; (Ref. 12693)
Dorsal soft rays (total): 12; Anal soft rays: 8. A member of the group of species with complete or nearly complete lateral line, 8 1/2 branched dorsal rays, 9+8 branched caudal rays and no sexual dimorphism. Can be distinguished by the following characters: 13-14 bars on body, the anterior ones not conspicuously wider than posterior ones; maximum head width 16.6-17.4% SL; eye diameter 3.1-3.6% SL, 14-17% HL; interorbital width 7.3-7.8% SL, 35-36% HL (Ref. 39226). Its slender caudal peduncle (1.23-1.53 times longer than deep) and its color pattern distinguish it from any congener (Ref. 39226). Presence of a dark blotch at dorsal-fin origin; a faint blotch at base of posterior rays of dorsal fin; scales very sparse or absent in front of dorsal fin and on belly (Ref. 12693).
Body shape (shape guide): elongated.
Inhabits streams and river backwaters at the driest time of the year (Ref. 39226). Frequently found in large rivers with stony bottom (Ref. 43281). A 5.92 cm SL female with ripe ovulae 1.4-1.6 mm in diameter (Ref. 39226). Not caught commercially (Ref. 12693).

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=0.00692 (0.00310 - 0.01545), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 2.8 ±0.26 se; based on food items.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
