The family of Butterflyfish get their name from their behavior offluttering around the reef. These fish typically have rather round and thin bodies. They are very colorful and some have extended snouts which they use to reach worms entrenched in the reef. They do spend their days pecking at coral and rockwork with their long, thin snouts in search of coral polyps, worms, and the many small invertebrates.These fish feeds on filamentous algae, small invertebrates, coral polyps, and fish eggs. Offer frozen butterfly food, chopped clams, enriched flake food or small pellets.Although they are considered easy to keep, they will do better is a system that has been established for at least six months.Some butterflyfish species travel in small schools, many are solitary until they find a partner, with whom they may mate for life.
