A close relative of the Angelfish, Butterfly Fish share many physical characteristics but are typically distinguished from Angelfish due to their more elongated, thinner “noses” which tend to jut out from their main body. Similarly vibrantly coloured and patterned (with the dominant colour usually a bright yellow), they add colour to what is already a vivid tapestry of rainbow-coloured marine creatures.The bodies of Butterfly Fish are very thin, which help them navigate through smaller passages so that they can dine on their usual diet of coral polyps or algae growing on the reef. Butterfly Fish are also known for being incredibly loyal to their mates, and stay with them for life.
