Butterflyfish

There are several species in the Chaetodontidae family, commonly known as the butterflyfish. These colorful, bony fish are most often found near coral reefs at depths from 1 to 100 feet. Some species of butterflyfish are carnivorous; their meals usually consist of worms, crustaceans and the fleshy part of corals called polyps. The rest are omnivorous, which means they eat animals as well as plants, such as algae.

Butterflyfish come in sizes between 6 and 12 inches, and usually have very bright colors. The Golden-striped Butterflyfish glows a beautiful yellow, almost like a tiny Sun in the water. The Ornate Butterflyfish is truly remarkable. Most of its body is a light blue, with bright orange stripes flaming across. The outer edge of the fish is a greenish color, with traces of yellow and black stripes.

This special family is easily recognized in the water because of its shape and beauty. Butterflyfish are rather flat and oval-shaped. A short 'snout' sticks out at one end, while a fan-shaped tail stems out from the back. The overall appearance of the fish makes them a popular pet.
