The Millenium Rainbow is a stunning addition to my planted tank. The male develops vibrant red colors quickly and stays very calm. I’ve had them for six months and they’re thriving in the 78°F water. Easy to care for and don’t stress the plants.

Beautiful fish with a lovely shimmer. They adapt well to my planted setup and don’t chase other fish. I keep the tank temperature below 80°F and they seem happy and active.

I was worried about compatibility with my plants, but these fish are peaceful and don’t damage the substrate or leaves. The colors are vivid and the fish look elegant in the tank.
