Chaetodontoplus septentrionalis
An angelfish from Japanese waters with vivid blue horizontal stripes on a yellow-tan body and a yellow tail. Juveniles are black with a yellow band. Up to 22cm. Common on rocky reefs of southern Japan; shy at first but does well once settled.
The Bluestriped Angelfish (Chaetodontoplus septentrionalis) is an angelfish of the family Pomacanthidae found in the western Pacific from southern Japan and Korea to Taiwan, southern China and the Malay Peninsula; the Japanese family name derives from this species. It reaches 22cm total length. Adults have vivid blue horizontal stripes on a yellow to tan body and a yellow caudal fin; in females the stripes run the full length of the body, while males have duller body stripes and blue lines on the face. Juveniles are black with a yellow bar behind the head and yellow markings on the fins. It is commonest on rocky reefs with large boulders and on rubble slopes at 2-30m, with juveniles staying close to crevices. It feeds on sponges and tunicates and is a protogynous hermaphrodite in which dominant females become males. Scarce and expensive abroad, it nevertheless often thrives in captivity: shy at first, it settles quickly in a stable tank. Provide 680L or more with plenty of hiding places and live rock. Semi-aggressive and prone to nipping stony and soft corals and clam mantles, so use caution in reef tanks. Overseas it is treated as a seasonal species with imports concentrated in summer.
