Remarks: A currently unidentified rainbowfish from Fletcher Creek, these fish range from olive green to neon yellow depending on mood. They have an interesting backstory, as they are likely the result of natural hybridization between their ancestor and M. splendida. Some M. splendida reportedly found their way into Fletcher Creek around 2015. The result is a beautiful species with long black fins, olive-orange stripes, and a golden shine.

The fish are omnivorous and should be fed a quality flake food with supplemental proteins such as baby brine shrimp. They require clean water but tolerate a wide variety of water parameters. By providing frequent water changes, you will be rewarded with nearly continuous spawning attempts. Melanotaenia species deposit eggs in weedy areas (often mimicked by a yarn mop) and the eggs hatch 7-10 days later. Eggs can be harvested for hatching in separate tanks to avoid predation. Most Rainbows show their best colors at sunrise, when the males display their bright fins for potential mates. Having more females than males will allow for proper color displays and avoid any unwanted aggression towards lone females.
