Ostorhinchus fleurieu (flower cardinalfish,[1][2] gold cardinalfish,[1] bullseye cardinalfish,[1] cardinalfish,[1] ring-tail cardinalfish[1] or ringtailed cardinalfish[1]) is a species of cardinalfish native to the Red Sea and Persian Gulf, the Gulf of Oman, and the waters around East Africa, Seychelles, India, Sri Lanka, the Indo-Malayan region, and Hong Kong.[3]


A coppery-coloured fish with a broad blackish bar at the base of the tail, it is up to 12.5 cm in length. In juveniles, the base of the tail has a spot rather than a bar. The upper jaw has a narrow blue streak, and a broad, blackish stripe extends from the front of the snout to the eye. It is easily confused with Ostorhinchus aureus, where the black tail bar is narrower in the centre than at the ends.


Adults occur in small schools made up of pairs of fish from 7 to at least 73 m in depth, associated with coral reefs.
