Rainbowfish are a small and very colorful freshwater fish, mostly found in northern and eastern Australia and New Guinea and in the Southeast Asian islands. Rainbow Fish grow up to at most 5 inches in length, with some varieties measuring less than 2 and a half inches.

Many aquarium hobbyists seem to prefer Rainbow Fish in their community tanks.
