Pempheris adusta, the dusky sweeper, is a species of marine ray-finned fish in the family Pempheridae, the sweepers. It is common species on coral reefs in the Indo-Pacific region.
Pempheris adusta has a depth range of 0–20 m (0–66 ft) and it is a common species of coral reefs where it forms aggregations during the day in caves or crevices or below overhangs. A few can sometimes be seen out in the open in the day, near the shelter provided by reefs. It has been recorded in small groups with Myripristis murdjan less than 1 m (3 ft) below the surface. It emerges from its shelters at night to feed on zooplankton.
Spawning takes place during April to June, although it occurs all year in Okinawa. Spawning takes place after sunset and only individuals with a standard length greater than 11 centimetres (4.3 in) join in the spawning group.
