Rainbow fish, also known as rainbow fish or Melanotaeniidae, are a family of fish native to Australia, New Guinea and Indonesia. The name "rainbow" comes from the colors these fish exhibit, especially during mating season.
Rainbow Fish - interesting facts and information
The most popular and recognizable species in this family is the Boesemana rainbow fish, which is prized for its intense, contrasting shades of blue and orange.
Rainbow fish tend to be calm and sociable, making them popular for keeping community aquariums. They are also known for their activity, often swimming in schools and jumping on the surface of the water.
Rainbow fish usually grow to about 10-15 cm in length, although some species can grow to 20 cm. Most species prefer warm, slightly acidic to neutral water and eat both plant and meat foods.
Unfortunately, many species of rainbow fish are threatened by habitat loss and pollution, and some are even classified as endangered. However, many aquarists are trying to breed these species in captivity to help preserve their populations.
