Description
The blackspot sweeper is a reef fish of the family Pempheridae from the Indo-West Pacific. The species reaches about 22 cm and has a deep, compressed, coppery body with large eyes and a black spot at the base of the pectoral fin, to which the name refers. It occurs in clear, shallow lagoon and seaward reefs and is common along the reef margin. By day it forms dense aggregations in caves; at night it hunts benthic and planktonic crustaceans, other small invertebrates and small fishes. Through its schooling behaviour the species is a familiar sight on the reef.
