About

Melanotaenia sp. "Baliem" originates from the Baliem Valley, a highland river valley in the central mountains of West Papua, where it inhabits cool, clear, well-oxygenated water. Its vivid colouration and highland adaptation set it apart from lowland relatives. Requires cooler temperatures than most melanotaeniids and excellent water quality to thrive.

Care Guide

Water: 20–25°C, pH 7.0–8.0, moderately hard, well-oxygenated water. Tank: 120 L+, good water flow and oxygenation, plants and open swimming areas. Feeding: Omnivore; varied diet of flakes, pellets, and frozen/live foods. Behaviour: Active, peaceful schooling fish; cooler temperatures are important. Compatibility: Best with other highland rainbowfish; avoid warm-water-only species.
