The twospined angelfish (Centropyge bispinosa ), also known as the dusky angelfish , or coral beauty , is a species of marine ray-finned fish , a marine angelfish belonging to the family Pomacanthidae . They are found in the Indo-Pacific .
Description [ edit ]
The twospined angelfish has a basic dark purplish-blue body. This is marked with irregular orange vertical bars on its flanks. The dorsal , caudal and anal fins have a bright blue margin.[3] The dorsal fin contains 14 spines and 17–18 soft rays while the anal fin has 3 spines and 17–19 soft rays. This species attains a maximum total length of 10 centimetres (3.9 in ).[2]
Distribution [ edit ]
The twospined angelfish is found in the Indo-Pacific. Its range extends from the coast of East Africa between Tanzania and South Africa as Far East as the Tuamotu Islands of French Polynesia , north to the Izu Islands of Japan and south to Lord Howe Island .[1] In Australia, as well as Lord Howe Island, it is found from the Rowley Shoals and Scott Reef in Western Australia , Ashmore Reef in the Timor Sea , and along the east coast from Raine Island in Queensland to Bass Point in New South Wales as well as Christmas Island . Offshore it occurs at Norfolk Island , Elizabeth Reef and Middleton Reef in the Tasman Sea and Ashmore Reef and Kenn Reef in the Coral Sea .[3]
Habitat and biology [ edit ]
The twospined angelfish is found at depths of 5 to 50 metres (16 to 164 ft ) in coral reefs within lagoons, rubble patches and drop offs, being commonest around drop offs.[1] They live in small social groups consisting of a single male and a few females. They are protogynous hermaphrodites and the most dominant of the females in a group will change sex to become male if the existing male dies or disappears.[3] This species feeds on algae and detritus .[4]
Systematics [ edit ]
The twospined angelfish was first formally described in 1869 by the German-born British ichthyologist and herpetologist Albert Günther (1830–1914) with the type locality given as Ambon Island , Indonesia.[5] In some classifications it is placed in the subgenus Centropyge .[6]
Utilisation [ edit ]
The twospined angelfish is frequently found in the aquarium trade.[1]
