Key Facts
- Geographic Range: Malinau, North Kalimantan (Indonesia), Sabah and Sarawak (Malaysia) and Brunei Darussalam. Restricted to high-gradient forest streams.
- Habitat: This species inhabits cool, clear, fast-flowing mountain streams with exceptionally high oxygen content. Substrates typically consist of rounded stones, gravel, and exposed bedrock. Vegetation is sparse; instead, biofilm, diatoms, and algae dominate the benthic surface. Light conditions vary from shaded forest cover to bright, sunlit riffles.
- Natural Water Parameters: • Temperature: 20–24°C • pH: 6.0–7.2 • Hardness: 50-150 ppm • Dissolved Oxygen: Very high DO due to strong current

Product information
Gastromyzon lepidogaster is a highly distinctive hillstream loach valued for its specialized morphology, reticulated patterning, and characteristic green dorsal side, making it a visually appealing choice for advanced aquascapes and river biotope aquaria. Its ecological adaptations and behavior provide both educational value and display interest. As the global hobby increasingly embraces rheophilic species, demand for Gastromyzon continues to grow, though supply remains tied to the conditions of remote headwater environments.
