Rainbow Fish Family
Some of the most mesmerizing creatures in the underwater realm are rainbow-colored fish, with iridescent hues that shine under light. The most famous of these among these are the members of the Melanotaeniidae family, which are commonly called rainbowfish. These fish are native to lakes, rivers, and swamps in Australia, New Guinea, and parts of Southeast Asia. Rainbowfish are small to medium-sized, slender torpedo-shaped bodies that are often subtly colored or metallic and may have a spectrum of colors from red through green to blue and purple. Those rainbowfish got their names because of that kaleidoscopic appearance.
While rainbowfish are visually stunning, they’re relatively easy to care for and thus are popular in the aquarium trade. It’s peaceful schooling fish, which means they like to live in groups. As a calm temperament, they make great tank mates to other non-aggressive species, adding beauty to a community aquarium.

To maintain good health, rainbow fish need a balanced diet of premium fish food flakes and pellets plus fresh frozen foods like brine shrimp and daphnia.

Rainbow Fish with Sharp Teeth
Most rainbowfish are generally quite docile, although a few species with sharp teeth and an eye-catching rainbow color can be found. These supposedly rainbow fish tend to live in the ocean as opposed to freshwater settings.
One example is parrot fish, which are found in tropical reefs. While not a genuine rainbowfish, their beak-like teeth aid them in scraping algae from coral. The many vibrant colors in their scales, which often contain shades of blue, green, and yellow, classify them as parrot rainbowfish.
On the other hand, freshwater rainbowfish, such as those in the Melanotaeniidae family, are devoid of sharp teeth and are entirely herbivorous or insectivorous. Instead, these species appeal to people due to their super colors and maintainable behavior, making them fit for peaceful community aquariums. In nature, their reflective scales serve as a defense, confusing creatures and flooding them with flashes of light.
