Asia: Chao Phraya basin, Thailand. Reported from the Mekong basin (Ref. 37773).

Biology     Glossary (e.g. epibenthic)

Inhabits mainstream rivers and floodplains (Ref. 58784). Omnivorous, feeding on plant matter and small benthic animal (Ref. 58784). Tens of thousands of specimens are exported annually from Thailand for the ornamental trade, all now captive bred (Ref. 12217). Aquarium keeping: solitary, adults are territorial and may 'bully' other fish; minimum aquarium size 120 cm (Ref. 51150).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (-0.15112 - 0.16346), b=3.05 (2.96 - 3.14), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.34 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 (23 of 100) .
Price category (Ref. 80766):   Unknown.
