Melanotaenia parva

Declining

Overview

The Lake Kurumoi rainbowfish is a species of freshwater rainbowfish in the subfamily Melanotaeniinae. It was endemic to West Papua in Indonesia. Its natural habitat was only the small Lake Kurumoi in the Bird's Head Peninsula. It is primarily threatened by habitat loss, however it is unknown if the wild population still exists as it has probably been extirpated from its entire native range.

Melanotaenia parva faces severe threats from habitat degradation in its extremely limited range around Lake Kurumoi in Papua New Guinea. Mining activities and agricultural expansion have altered water chemistry and sedimentation patterns in the lake system. The species' tiny population size makes it exceptionally vulnerable to any environmental disturbance, with pollution from nearby human activities posing an ongoing risk to water quality.
