Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Betta fusca faces severe habitat destruction from rapid deforestation and agricultural expansion across its limited range in Peninsular Malaysia. Peat swamp forests, the species' primary habitat, are being drained and converted at alarming rates for palm oil plantations and urban development. Water pollution from agricultural runoff and industrial activities further degrades the acidic, tannin-rich waters this species requires for survival.
Habitat
Betta fusca inhabits shallow, slow-moving waters in peat swamp forests of Peninsular Malaysia, preferring acidic, tannin-stained waters with dense vegetation cover. The species is typically found in forest streams, ditches, and temporary pools within primary and secondary peat swamp ecosystems.
