Flower Cardinalfish

The flower cardinalfish[2] (apogon fleurieu) is the type species of the cardinalfishes.

Contents

Range

Red Sea and Persian Gulf, Gulf of Oman and East Africa, Seychelles, India, Sri Lanka, the Indo-Malayan region and Hong Kong.[3]

Description

A coppery-coloured fish with a broad blackish bar at the base of the tail 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. Easily confused with Apogon aureus, where the black tail bar is narrower in the centre than at the ends.

Habitat

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