Australian and New Guinea Rainbowfish

Rainbowfish are a group of small colorful fish found in the rivers and lakes of Australia and New Guinea. They are active swimmers, often schooling near the surface of the aquarium. Rainbows will vary in size from the dwarf Pseudomugil species (including Threadfin and Forktail rainbows, etc) maxing out around 1.5 inches to the larger Melanotaenia species (including Boesemanii and Turquoise rainbows) reaching 4 inches. All species of Rainbowfish are perfectly suited for community aquariums.
