Overview

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

Parosphromenus harveyi faces severe habitat degradation from palm oil plantation expansion and logging activities throughout its native peat swamp forests in Borneo. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes, while water pollution from agricultural runoff and industrial activities threatens the acidic, tannin-rich waters essential for its survival. Collection pressure for the international aquarium trade has further reduced wild populations of this prized ornamental fish.

Threat summary

Habitat

Parosphromenus harveyi inhabits shallow, acidic peat swamp forests and associated blackwater streams in Borneo, preferring areas with dense vegetation cover and soft, tannin-stained water. The species requires specific water chemistry conditions with low pH and minimal mineral content, typically found in undisturbed peat bog ecosystems.
