Multisquamata Rainbowfish
Multisquamata Rainbows are native to the Mamberamo River in Papua New Guinea. They resemble Emerald Rainbows but have a darker overall coloration. Males develop dark green fins with yellow-orange lines along the abdomen. Once mature, they may exhibit elongated anal and dorsal fin rays, giving a tattered appearance.
The fish are omnivorous and thrive on a high-quality flake food supplemented with proteins like baby brine shrimp. They prefer clean water and can tolerate a wide range of water conditions. Regular water changes encourage frequent spawning, as they deposit eggs in weedy areas—often mimicked by yarn or aquatic plants.

The fish are active and colorful, especially the males with their bright green fins and yellow lines. I’ve noticed them spawning regularly after setting up a planted tank with some floating plants. Easy to care for and very engaging to watch.

They adapted well to my tank after a few weeks. I feed them flakes and a few brine shrimp each day. The water changes I do weekly seem to trigger spawning. Not the most flashy, but they’re peaceful and interesting to observe.

Great addition to a community tank. The fish are hardy and don’t stress easily. I placed some yarn in the tank to mimic weedy areas, and they started laying eggs within a month. Very rewarding to watch.
