Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Betta simorum faces severe pressure from habitat destruction as peat swamp forests in Peninsular Malaysia are cleared for palm oil plantations and urban development. Water pollution from agricultural runoff and industrial activities degrades the acidic, tannin-rich waters this species requires for survival. The aquarium trade poses an additional threat, with wild populations being harvested for the international ornamental fish market.
Habitat
Betta simorum inhabits shallow, slow-moving waters in peat swamp forests of Peninsular Malaysia, particularly in areas with dense vegetation and acidic, tannin-stained water. The species is typically found in forest streams, ditches, and temporary pools within primary and secondary peat swamp ecosystems.
