Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Betta foerschi faces severe habitat degradation from palm oil plantation expansion and logging activities throughout its native range in Borneo. Water pollution from agricultural runoff and mining operations has contaminated the shallow forest streams this species depends on for breeding and survival. The aquarium trade has also placed additional pressure on wild populations, with collectors targeting this attractive species for international export.
