The butterflyfish of the Red Sea (Heniochus intermedius) is a Chaetodontidae, very common tropical fishes living in the reef. They are diurnal animals and feed on coral polyps, mucus, eggs and the small invertebrates hidden there. They have different, always very bright, colours. This picture shows the butterflyfish of the Red Sea, a species with a variable behaviour: they can live in schools or sometimes in pairs. They are diurnal fishes and feed on zoo-plankton. They can be up to 18 cm long and live only in the Red Sea, even if they are often taken for other similar species living also in other tropical seas.
