Betta schalleri

Unknown

Overview

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

Betta schalleri faces severe habitat degradation from palm oil plantation expansion and logging activities throughout its native range in Borneo. Water pollution from agricultural runoff and sedimentation from deforestation directly impacts the shallow, slow-moving waters this species requires for breeding and survival. The species' limited distribution makes it particularly vulnerable to localized habitat destruction, with entire populations potentially eliminated by single development projects.

Threat summary

Habitat

Betta schalleri inhabits shallow, slow-moving streams and swampy areas in lowland tropical rainforests of Borneo. The species prefers areas with dense vegetation cover, soft substrates, and slightly acidic water conditions typical of Southeast Asian peat swamp ecosystems.
