Parosphromenus parvulus

Unknown

Overview

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

Parosphromenus parvulus faces severe pressure from peat swamp forest destruction across its limited range in Peninsular Malaysia and southern Thailand. Palm oil plantation expansion and urban development have eliminated much of its specialized blackwater habitat, while water pollution from agricultural runoff degrades remaining forest streams. The species' extremely restricted distribution makes it particularly vulnerable to localized habitat loss, with some populations already extirpated from formerly suitable areas.

Threat summary

Habitat

This small gourami inhabits shallow, acidic blackwater streams and pools within primary peat swamp forests, typically in areas with dense vegetation cover and soft, organic substrates. The species requires very specific water chemistry conditions, including low pH and high tannin content characteristic of undisturbed peat swamp ecosystems.
