Habitat and Ecology [top]
Habitat and Ecology: The species inhabits larger streams and rivers, typically with turbid water and a sandy/muddy substrate. It feeds on crustaceans and other small benthic animals (Taki 1978) and spawns at the beginning of the rainy season in flooded riparian forests, with juveniles beginning to appear in August (Rainboth 1996).
Clear preference for deep water pools in dry season. (Baran et al. 2005).
Systems: Freshwater
Continuing decline in area, extent and/or quality of habitat: Unknown
Movement patterns: Full Migrant
Use and Trade [top]
Use and Trade: This species is caught for food in artisanal fisheries, and juveniles are occasionally caught and exported as ornamental fishes.
Threats [top]
Major Threat(s): The threats to this species are unknown, since there is no information on the biology of this species and therefore the impact of potential threats (especially those of an anthropogenic nature) remains unknown. The current threats to aquatic biodiversity in all of its known distribution have also not been adequately identified.
Conservation Actions [top]
Conservation Actions: There is insufficient information on the distribution, biology and potential threats for this species. Catch data for this species are also needed.
