False moorish idols (Heniochus diphreutes) shoaling over a coral reef. This fish generally inhabits seaward reef slopes in areas of strong current. It feeds mainly on plankton, but is known to act as a cleaner, eating parasites from the skin of larger fish. It can reach a length of around 20 centimetres. Photographed on the Fakarava Atoll, French Polynesia, in the Pacific Ocean.
