  1. Diversity of species: There are many species of fish that are referred to as "rainbow fish," such as the roseate iris (Melanotaenia splendida), the shiner iris (Melanotaenia lacustris) and the spotted iris (Melanotaenia praecox). Many of these fish belong to the iris family (Melanotaeniidae).
  2. Freshwater poverty: Most rainbow fish are found in freshwater such as lakes, rivers and streams. They are generally present in Australia, New Guinea, Indonesia and some other areas of Oceania.
  3. Colorful coloration: A distinctive feature of rainbow fish is their bright and varied coloration. Shades can include pink, blue, yellow, orange, green and more.
  4. Aquarium fish: Due to their attractive coloration, many species of rainbow fish are kept as aquarium fish. These fish are popular among aquarium hobbyists for their aesthetics and temperament.
  5. Food: Rainbow fish are usually omnivorous, feeding on both aquatic plants and small aquatic organisms. In aquariums, they require a proper diet that provides them with the right nutrients.
  6. Breeding: Raising rainbow fish can be complicated, due to their water quality, temperature and feeding requirements. They require well-maintained and balanced aquarium conditions.
  7. Cultural significance: In some cultures, rainbow fish are a symbol of beauty, color and nature. Because of their coloration, they are often seen as an example of harmony and aesthetics.
  8. Protection and environment: Some rainbow fish species are endangered due to habitat loss, water pollution and other factors affecting their habitat.


  1. Variety of colors: Rainbow fish are known for their amazing and diverse coloration. Their hues and patterns are so varied that it seems as if they carry little rainbows on them.
  2. New Guinea - the land of irises: New Guinea, especially its Papua New Guinea area, is particularly known for its diversity of rainbow fish. There are many species of rainbows in this region, and some of them are endemic, meaning they are only found in this specific location.
  3. Male and female: In many species of rainbow fish, males have more intense and bright colors than females. This is often related to the process of courtship and mate attraction.
  4. Mating parades: During the courtship process, the male rainbow fish often displays impressive behavior and displays of color to attract the attention of the female. This spectacular behavior is often observed in aquariums.
  5. Rainbow on a floating mantle: Some species of irises, such as the roseate iris (Melanotaenia splendida), have extremely intense colors that resemble a rainbow, especially when the fish floats on the surface of the water.
  6. Peak season: In many regions, rainbow fish reach their peak mating season during the rainy season, when water levels are higher.
  7. Endemic species: Some species of irises are endemic to specific lakes or rivers. This is due to the geographical isolation of these areas.
  8. Threats: Due to habitat loss, water pollution and the risk of invasive species introduction, many iris species are endangered. Protecting their natural habitats is crucial to their survival.
  9. Rainbow fish in aquariums: Due to their beauty and vivid colors, rainbow fish are often chosen as aquarium fish. Breeders try to maintain proper conditions in aquariums to bring out the full colors of these fish.
  10. Research: Rainbow fish are also the subject of scientific research in genetics and evolutionary biology to understand the mechanisms affecting their color diversity and evolution.
