Copper Sweeper Pempheris oualensis

Sweepers are several species of small fish with big eyes due to their nocturnal lifestyle. They like clear, shallow waters where they hunt at night in the sand for tiny crustaceans and fish. They hide in caves in the day. They are often found with other small, big-eyed reef fish like Cardinalfish.

The Copper Sweeper is native to the Indo-Pacific. It has a coppery sheen and a black spot at the base of its copper-coloured pectoral fins. It grows to 20cm long.
