Betta cracens

Unknown

Overview

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

Betta cracens faces severe threats from habitat destruction due to deforestation and agricultural expansion in its native peat swamp forests of Peninsular Malaysia. Water pollution from palm oil plantations and urban development has degraded the acidic, tannin-rich waters this species requires for survival. The extremely limited range makes the entire population vulnerable to single catastrophic events, while collection for the ornamental fish trade adds additional pressure on wild populations.

Threat summary

Habitat

Betta cracens inhabits shallow, slow-moving acidic waters in peat swamp forests of Peninsular Malaysia. These specialized environments feature soft, tannin-stained water with dense vegetation and fallen logs that provide essential cover and breeding sites.

Frequently asked questions

Why is Betta cracens classified as Critically Endangered?
Betta cracens 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 cracens faces severe threats from habitat destruction due to deforestation and agricultural expansion in its native peat swamp forests of Peninsular Malaysia. Water pollution from palm oil plantations and urban development has degraded the acidic, tannin-rich waters this species requires for survival. The extremely limited range makes the entire population vulnerable to single catastrophic events, while collection for the ornamental fish trade adds additional pressure on wild populations.
Where does Betta cracens live?
Betta cracens 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 cracens?
The main threats to Betta cracens 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.
