Overview

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

Betta chloropharynx is confined to blackwater peat swamp forests in Sumatra, Indonesia, a habitat undergoing rapid conversion to oil palm and pulpwood plantations. Drainage of peat swamps for agriculture alters water chemistry and acidity levels this species depends on, while remaining fragments face further degradation from fire and logging. Its narrow endemic range leaves it with little buffer against continued habitat clearance, and localized collection for the aquarium trade adds further pressure on small wild populations.

Threat summary

Frequently asked questions

Why is Betta chloropharynx classified as Critically Endangered?
Betta chloropharynx is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Betta chloropharynx is confined to blackwater peat swamp forests in Sumatra, Indonesia, a habitat undergoing rapid conversion to oil palm and pulpwood plantations. Drainage of peat swamps for agriculture alters water chemistry and acidity levels this species depends on, while remaining fragments face further degradation from fire and logging. Its narrow endemic range leaves it with little buffer against continued habitat clearance, and localized collection for the aquarium trade adds further pressure on small wild populations.
Where does Betta chloropharynx live?
Betta chloropharynx occurs in Indonesia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Betta chloropharynx?
The main threats to Betta chloropharynx are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
