Cato River Rainbowfish
The Cato River Rainbowfish is a rare gem among Australian native fish, known for its brilliant electric blue and olive tones, often with subtle gold highlights. This striking rainbowfish variety is highly sought after by collectors and aquascapers alike for its unique colour pattern and lively group behaviour.
Native to the clear waters of the Cato River in Queensland, this Melanotaenia trifasciata strain is both hardy and adaptable, making it an ideal choice for both seasoned aquarists and those new to keeping Australian rainbowfish. In a planted aquarium with good lighting, these fish truly shine—literally.
Care Overview:
Cato River Rainbowfish do best in schools of 6 or more and appreciate plenty of swimming space. These active mid-to-top dwellers prefer stable, warm freshwater with gentle current and natural décor like driftwood and plants. A balanced diet of quality flakes, micropellets, and live or frozen treats like baby brine shrimp will help bring out their full colour potential.
With their peaceful nature and striking appearance, the Cato River Rainbow is perfect for community tanks and biotope setups focused on Australian freshwater species.
