Description
editChaetodon mesoleucos has a bluish white anterior part of the body with a vertical black band running through the eye. The rest of the body is pale grey in colour marked with numerous vertical black lines. The caudal fin is black with a white on the inner margin near the caudal peduncle.[3] This species attains a maximum total length of 13 centimetres (5.1 in), although 12 centimetres (4.7 in) is more common.[2]
Distribution
editChaetodon mesoleucos is found in the northwestern Indian Ocean. It occurs from the central Red Sea, into the Gulf of Aden and around Socotra.[1]
Habitat and biology
editChaetodon mesoleucos occurs at depths between 1 and 25 metres (3.3 and 82.0 ft),[1] inhabiting coral reefs where they occur in pairs.[2] They are thought to feed mainly on coral polyps but will eat a variety of benthic invertebrates.[3] Little is known about the biology of this species.[1]
Systematics
editChaetodon mesoleucos was first formally described in 1775 by the Swedish-speaking Finnish explorer, orientalist, naturalist Peter Forsskål (1732-1763), his description was published in 1775 by his companion on his expedition to Yemen, the orientalist and mathematician Carsten Niebuhr. The type locality was given as Al-Mukhā in Yemen.[4] It belongs to the large subgenus Rabdophorus which might warrant recognition as a distinct genus.[5]
Utilisation
editChaetodon mesoleucos is uncommon in the aquarium trade.[1] However, it is not a difficult species to keep in captivity.[3]
