Black Back Butterflyfish

Black Back Butterflyfish (Chaetodon melannotus)

The Black Back Butterflyfish is a vibrant species found in the coral reefs of the Indo-Pacific region. Recognizable by its distinct color pattern, it has a bright yellow body with a striking black patch covering its upper back, hence its name. The fish also features a bold, black vertical band running through its eye, which helps in camouflaging from predators. Typically reaching up to 15 centimeters in length, the Black Back Butterflyfish is an omnivorous feeder, consuming algae, small invertebrates, and coral polyps.

In addition to their captivating appearance, Black Back Butterflyfish are known for their monogamous behavior, often seen swimming in pairs. This pairing is believed to strengthen their bond and increase their efficiency in foraging and avoiding predators. They are a vital part of the reef ecosystem, contributing to the health and balance of coral communities by controlling algae growth and preying on coral parasites. Their presence is a good indicator of reef health, and their vibrant colors make them popular among divers and aquarium enthusiasts alike.
