The Copperband Butterflyfish (Chelmon rostratus) is a species of tropical marine fish belonging to the family Chaetodontidae. It is also commonly known as the Beaked Coralfish or Orange Stripe Butterflyfish. Here are some key features and information about the Copperband Butterflyfish:
Appearance: The Copperband Butterflyfish has a laterally compressed body with a pointed snout and a small mouth. Its body is primarily white with a series of alternating vertical bands of orange and yellow, giving it a distinctive appearance. It has a black eye band, a black spot near the base of the tail, and long, filamentous dorsal and anal fins.
Size: These butterflyfish typically grow to about 6-8 inches (15-20 cm) in length, although some individuals can reach up to 10 inches (25 cm).
Distribution: They are native to the Indo-Pacific region, including the waters around Indonesia, Philippines, Malaysia, and Australia. They can be found in coral reefs and lagoons, usually in areas with rich coral growth.
Behavior: Copperband Butterflyfish are primarily diurnal (active during the day) and are generally solitary or found in pairs. They are known for their graceful swimming and are often seen gliding slowly over coral reefs, searching for their preferred food.
Diet: These butterflyfish have a specialized diet, primarily feeding on small invertebrates such as worms, crustaceans, and small coral polyps. They are particularly known for their ability to prey on Aiptasia anemones, which are considered pests in aquariums. In captivity, they can be fed a varied diet consisting of frozen or live foods, including brine shrimp, mysis shrimp, and other meaty preparations.
Aquarium Care: Copperband Butterflyfish are a popular choice for reef aquariums due to their striking appearance. However, they can be somewhat challenging to care for due to their specific dietary requirements. They prefer a well-established aquarium with plenty of live rock and hiding places. It is important to ensure that the tank has a sufficient supply of food to sustain them. They are generally not aggressive toward other fish but may exhibit territorial behavior towards their own species or similar-looking butterflyfish.
