The Fasinensis Rainbow (Melanotaenia fasinensis) is a stunning species of rainbowfish native to the streams and rivers of Papua New Guinea. Renowned for its vibrant and iridescent colors, this fish displays a beautiful mix of blues, greens, and yellows that become even more pronounced with age and proper care. The Fasinensis Rainbow is peaceful and active, making it a delightful addition to community aquariums. They thrive in well-maintained tanks with clean, well-oxygenated water and a balanced diet of high-quality flakes, pellets, and live or frozen foods. Their lively behavior and striking appearance make them a favorite among aquarists.
