The Red Irian Rainbow is favorite among those that keep rainbowfish. This fish is a very bright uncompromising red color. They, like the Turquoise Rainbows grow to 3 or 4 inches long maximum and can live around 4 or 5 years commonly. They are excellent community tank fish that are very active. We highly recommend these fish for most community aquariums. Some fish can be upset by there constant motion and activity.
