Red Rainbowfish (New Guinea Rainbowfish)
A beautiful and larger-growing species of rainbowfish, the New Guinea Red Rainbow makes for a stunning centerpiece fish for medium to large community or planted aquariums. With their deep red coloration (more intense in males) and extremely active nature, they add a splash of color to almost any freshwater aquarium. As with most rainbowfish, they are best kept in groups of 5 or more fish and will do best in an aquarium with ample cover (such as live or artificial plants).

The Red Rainbowfish are vibrant and active, adding a lot of energy to my 55-gallon tank. I kept them in a group of six with plenty of floating plants, and they seem very healthy. The red color stands out well against the background.

Great addition to my planted aquarium. The fish are lively and stay active throughout the day. I noticed the males have a stronger red hue, which is very eye-catching.

I’ve had these fish for three months now and they’re thriving. They don’t stress other community fish and enjoy the plant cover. Very satisfied with the purchase.
