Short description Morphology | Morphometrics

Dorsal soft rays (total): 12; Anal soft rays: 8. Consists of 10-12 dark bars usually vertically split; 8+8 branched caudal rays; 8 1/2 branched dorsal rays; males with a suborbital flap and absence of median notch in lower jaw (Ref. 39226). Lateral line complete or incomplete, at least reaching to tips of pelvic fins; caudal fin with 5-7 very irregular rows of spots on rays; scales lacking between pectoral fins, but present on back (Ref. 12693).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Asia: southeastern Thailand in provinces Trat, Chantaburi, Chonburi and on Koh Chang island; apparently restricted to small coastal streams (Ref. 39226), but may possibly be found all along the mountain range, including the Mekong basin (Ref. 12693).

Biology     Glossary (e.g. epibenthic)

Inhabit small, shallow, high gradient streams with gravel and boulder substrates in forests. Diet probably consists of insect larvae and some algae, as seen in other nemacheilines (Ref. 12693). A female 5.24 cm SL contains ovulae about 0.7 mm diameter (Ref. 39226).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00491 (-0.19173 - 0.20154), b=3.07 (2.96 - 3.18), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.6   ±0.27 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (13 of 100) .
Price category (Ref. 80766):   Unknown.
