Description

Centropyge tibicen is mainly black in colour, the adults have an elongated vertical black blotch in the centre of the upper flanks. Smaller fish are mainly black with a white vertical bar which changes to a central blotch and becomes highly variable in form and extent. The dorsal and anal fins have a blue line just below their margin. Much of the pelvic and the front part of the anal fin are yellow. The caudal fin has a blue line which is positioned submarginally. The dorsal fin contains 14 spines and 15-16 soft rays while the anal fin has 3 spines and 16-17 soft rays. This species attains a maximum total length of 19 centimetres (7.5 in).[2]

Distribution

Centropyge tibicen Is found in the Indo-Pacific region. It occurs from northwestern coast of Australia and Christmas Island east through the Indo-Australian Archipelago to Vanuatu and Tonga in the east. They extend as far north as, southern Japan and Taiwan and to Lord Howe Island.[1]

Habitat and biology

Centropyge tibicen is found at depths between 4 and 35 metres (13 and 115 ft).[1] It is an uncommon species of areas where there is a mixture of coral and rubble on both lagoon and seaward reefs. It is herbivorous and algae dominates its diet. It lives in harems of 3-7 fishes.[2] This species is able to change sex from female to male, when there is no male in a harem, one of the females changes sex.[3]

Systematics

Centropyge tibicen was first formally described as Holocanthus tibicen in 1831 by the French anatomist Georges Cuvier (1769-1832).[4] The specific name tibicen means “trumpeter”, this is thought to be alluding to the name given to this species by the Dutch naturalist François Valentijn (1666-1727) in 1726, Japonfche Trompetter.[5] When Johann Jakob Kaup described the genus Centropyge in 1860 he named Cuvier’s H. tibicen as the type species.[6] As the type species it is placed in the subgenus Centropyge.[5]

Utilisation

Centropyge tibicen is frequently found in the aquarium trade.[1]
