The Lake Kutubu Rainbowfish, also called the Turquoise Rainbowfish, is native only to Lake Kutubu and its tributary river in Papua New Guinea. With its restricted range, it is at high risk of becoming extinct in the wild. Males are slightly larger and more brightly coloured than females. They grow to 12cm long.
