Native to slow-flowing rainforest streams of Papua New Guinea, this fish adds an unmistakable shimmer and liveliness to any planted or nano aquarium.

Active and social, they thrive best in groups of six or more, where males display vibrant colors and perform elegant courtship dances. They prefer gentle filtration, clean water, and densely planted tanks with floating plants that diffuse the light.

Feed them a varied diet of high-quality micro pellets, baby brine shrimp, and daphnia to bring out their full coloration. Ideal tankmates include peaceful nano fish like rasboras, small tetras, and shrimp.
