Etymology: Discherodontus: Greek, di = two + Greek, scheo, scheros = to carry + Greek, odous = teeth (Ref. 45335).
Eponymy: Charles C Ashmead lived in Philadelphia and collected locally in Pennsylvania. He was an early local contributor to the Philadelphia Academy of Natural Sciences’ fish collection. (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Tropical
Asia: Mekong (Ref. 27732) and Maeklong basins (Ref. 26580).
Length at first maturity / Size / Weight / Age
Maturity: Lm 5.5 range ? - ? cm
Max length : 13.6 cm SL male/unsexed; (Ref. 27732)
Last simple dorsal ray feebly serrated posteriorly; a large black apical blotch on the dorsal fin; a bright red caudal fin without black lobe tips when live (Ref. 27732).
Seems to be associated with streams and rivers with clear water, moderate to fast current and a gravel to stony bottom (Ref. 27732). Found near the bottom in pools of small to medium-sized rivers. Typically occurs near decaying plant debris where it feeds on insects and other invertebrates. Possibly moves out into flooded forests during high-water periods. Apparently found in localized populations and encountered sporadically (Ref. 12693). Reported as a nocturnal species by villagers in Ban Pakphanang (Laos), where all specimens were obtained at night (Ref. 27732). Rare in markets (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00612 - 0.01712), b=3.00 (2.86 - 3.14), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.41 se; based on food items.
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
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).
