Profiles Tropical Rainbows

The rainbowfish are a family (Melanotaeniidae) of small, colourful, freshwater fish found in northern and eastern Australia, New Guinea, islands in Cenderawasih Bay, and the Raja Ampat Islands.

These Rainbow fish profiles show the best water conditions and fish tank set up to keep them in, although it is common to have rainbow fish in a community or planted freshwater aquarium. We have also listed in these fish profiles the best tank mates for rainbow fish as well as breeding and sexing information.
