Tusk fish are members of the Wrasse family. They are named for their tusk-like canine teeth in the front of their jaws.
The Venus Tusk Fish is the largest of the group. It is extremely variable in colour, the basic tone ranging from green through pale blue to pink and brick red. The most permanent colour seems to be the large bright blue spots well distributed over the head and body.
It is a very good table fish, the flesh being firm, white, flaky and of very good flavour.
