Chaetodontoplus septentrionalis is also known as the Bluestriped Angelfish or Blue-lined Angelfish. This very beautiful and distinctly colored angelfish is found in the water of southern Japan, southern Korea, Taiwan, Hong Kong, and Vietnam. Commonly seen on rocky shores at depths between 5 - 60 m in southern Japan from the Izu Islands southward, but is scarce in the Ogasawara Islands and also is very curiously absent from the Ryukyu Islands (Okinawa).
Chaetodontoplus septentrionalis is completely absent from the sea around Okinawa, this is very mysterious. A distinct variation is known from Vietnam that has a more complicated color pattern especially on the head and face, similar in appearance to the Orangeface Angelfish C. chrysocephalus from Indonesia.
The Bluestriped angelfish is an overall brown to brownish yellow with blue horizontal lines on their sides. Many of these lines are curving and some may be interrupted. The caudal fin is entirely yellow with a narrow blue edge. The pelvic fins are yellow, the pectoral fins duskier with a black spot encircled by blue at base, and the dorsal and anal fins are a blackish blue with several narrower blue lines. The face and head are yellowish brown with a mix of blue stripes and dots. No sexual differences are known.
In the wild the Bluestriped angelfish eat primarily sponges and tunicates, but have also been observed nibbling on macroalgae, black corals, and sea whips. It is not a reef safe fish as it will feed on some corals and sessile inverts. Chaetodontoplus septentrionalis dwells in subtropical to temperate areas so temperatures between 18 – 24° C MAXIMUM will serve them well.
Remarks:
Most large angelfish are well known for nipping at large-polyped stony corals and some soft corals as well as tridacnid clam mantles.
