Description

The yellow assessor is a small, brightly coloured reef fish (Plesiopidae) from the western Pacific, around the Great Barrier Reef. The species grows to about 6 cm and has a deep, bright-yellow body. As a reef-dweller it lives in small groups in caves and under overhanging coral, where it often hovers upside down just below the ceiling, and picks small zooplankton. The male broods the eggs in its mouth. The fish is harmless to humans and is prized in the aquarium trade.
