Description

Also known as Blue Tuskfish, Green Wrasse, Purple Grouper, Rainbowfish, Tuskfish, Yellow-bellied Tuskfish.

Found singly over sand and weedy reef flats in shallow coastal waters of lagoons and seaward reefs.
They feed on hard shell invertebrates.
Length - 100cm
Depth - 10-60m
Widespread Indo-West Pacific

Most reef fish seen by divers during the day are grazers, that cruise around just above the surface of the coral or snoop into crevices looking for algae, worms and small crustaceans.
Wrasses have small protruding teeth and graze the bottom taking in a variety of snails, worms, crabs, shrimps and eggs. Any hard coats or thick shells are then ground down by their pharyngeal jaws and the delicacies inside digested.
From juvenile to adult wrasses dramatically alter their colour and body shapes.
Wrasses are always on the go during the day, but are the first to go to bed and the last to rise.
Small wrasses dive below the sand to sleep and larger wrasses wedge themselves in crevasse Ref: https://www.fishbase.se/summary/Choerodon-schoenleinii
