Fin's Fish Guide
The Arc eye (Paracirrhites arcatus) is a saltwater fish of the family Cirrhitidae that grows up to 20 cm.
Description
The arc-eye hawkfish is a hawkfish (Cirrhitidae) from the Indo-Pacific. The species grows to about 14 cm and has a red-brown to olive body with a conspicuous, colourful arc behind the eye, to which the name refers. Like all hawkfishes it lacks a swim bladder and props itself on coral with its thickened, free lower pectoral fin rays, where it sits motionless on the lookout. It occurs in lagoons and on seaward reefs from 1 to at least 33 m, often on heads of branching coral. As an ambush hunter it springs on small crustaceans and small fishes. The species is harmless to humans.
