Utchee Creek Rainbowfish
The Utchee Creek Rainbow is very closely related to M. duboulayi, the Crimson Spotted Rainbow, and evidence can be seen in the bright red spot on the gill plate. Contrary to the Crimson Spotted Rainbows, these fish are typically found in moderate- to fast-flowing water over stones with little vegetation.
These 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.

The fish are active and colorful, especially during spawning season. I keep them in a well-filtered tank with flowing water and a yarn mop for egg placement. They eat flake food and baby brine shrimp regularly. Spawning happens every few weeks after water changes.

Great addition to a community tank. They’re hardy and adapt well to my water conditions. I feed them flakes and a bit of brine shrimp weekly. The red gill spot is very noticeable and adds to their appeal.

I’ve had them for three months and they’ve been consistently spawning. The water changes I do every two weeks keep the tank clean and the fish active. They don’t require special water parameters, which makes them easy to maintain.
