Rainbowfish are colorful freshwater fish native to Australia, Papua New Guinea, and parts of Indonesia, where they inhabit streams, rivers, lakes, and swamps. They belong to several groups, ranging from active species like Melanotaenia to smaller, more delicate Blue Eyes and Threadfin Rainbowfish. Their brilliant colors become especially striking as adult males display their fins to attract females, making them popular choices for community aquariums.

Rainbowfish are generally peaceful and thrive in well-filtered aquariums with plenty of swimming space, plants, and hiding spots. Most larger species should be kept in groups of six or more and can live alongside similarly sized, non-aggressive fish. These omnivorous freshwater fish need a varied diet of plant-based and protein-rich foods, including flakes and frozen or live foods. Rainbowfish scatter their eggs among vegetation and provide no parental care after spawning, with eggs typically hatching within 7–21 days depending on the species and water temperature.
