The effect created by undulating their thin, flattened colourful bodies as they navigate through the reefs give these fish the name ‘copperband’. Vertical yellow stripes are spread evenly over their white silvery bodies, and there is a distinct dark spot on their dorsal fins. They also have long snouts, which help them extract food from coral reefs.

Copperband butterflyfish usually have four vertical yellow stripes. One of them is aligned to run across their eyes!
