Melanotaeniidae

Rainbowfishes are small, colourful freshwater fishes belonging to the family Melanotaeniidae, found in northern and eastern Australia, New Guinea (including islands in Cenderawasih Bay and Raja Ampat Islands in Indonesia), Sulawesi and Madagascar.

The Pseudomugilidae, the blue-eyes, are a family of atheriniform fish. They have variously been treated as either a family of their own or as a subfamily of the Melanotaeniidae. They inhabit fresh and brackish water in Australia, New Guinea and nearby smaller islands. Blue-eyes are small fish, typically no more than in length. Like the larger melanotaeniid rainbowfish, they spawn all year round, and attach their eggs to vegetation.

Bedotiidae are a family of fish in the order Atheriniformes. They are closely related to the Australian rainbowfish family Melanotaeniidae, and were formerly placed in it as a subfamily, but are now considered a distinct family. They are commonly known as the Madagascar rainbowfish, Madagascan rainbowfish, or Malagasy rainbowfish due to their endemism to Madagascar. It includes two genera, Bedotia and Rheocles.

The Telmatherinidae, the sail-fin silversides are a family of atheriniform fish, inhabiting fresh and brackish water. All but the species Kalyptatherina helodes are restricted to the Indonesian island of Sulawesi, and most are found solely in the Malili Lake system, consisting of Matano and Towuti, and the small Lontoa (Wawantoa), Mahalona and Masapi. They were formerly treated as a subfamily of the Melanotaeniidae.
