I added a male New Guinea Rainbow to my 20-gallon planted tank. It has grown steadily and shows vibrant red coloration. The fish is active and peaceful, and it blends well with the live plants. Water temperature stays below 84F, which seems to be ideal for its health.

The fish arrived healthy and has been thriving in my tank for three months. The silver-gold shimmer of the female is quite striking. I appreciate how hardy they are compared to other tropical fish.

I was worried about compatibility with my planted setup, but the rainbow has done well. It doesn’t stress the plants and seems to enjoy the environment. Good filtration and stable temperature are key for success.
