Rainbowfish are a group of brightly colored freshwater fish native to Australia and New Guinea. They are popular in the aquarium trade due to their vibrant coloration, hardiness, and ease of care. Rainbowfish belong to the family Melanotaeniidae and typically grow to be 2-6 inches in length. They are omnivores and feed on small insects, crustaceans, and plant matter. They are also known to be social, active fish that prefer to live in shoals in their natural habitats. Currently I have no rainbowfish for sale, but encourage you to check out the superb selection and quality at Dansfish.
