Rainbowfish

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

The largest rainbowfish genus, Melanotaenia, derives from the ancient Greek melano (black) and taenia (banded). Translated, it means "black-banded", and is a reference to the often striking lateral black bands that run along the bodies of those in the Melanotaenia genus.
