Introduction

The Sydney Cardinalfish is endemic to (only known from) Australia. The species name limenus comes from the Greek word limen, meaning harbour or refuge and refers to the habitat of the species.

Identification

The Sydney Cardinalfish has pink fins and a broad mid-lateral stripe. There is a wide gap between the second and third stripes and a short stripe running posteriorly from the top of the eye. A large spot is present on the caudal peduncle.

Habitat

This species lives in rocky estuaries and offshore reefs at depths between 1 m and 30 m.

Distribution

It is endemic to Australia, occurring from southern Queensland to southern New South Wales, but probably also in eastern Victoria.

The Sydney Cardinalfish is very common in the Sydney region. Many of the specimens used in the original description of the species by Randall and Hoese, were collected from Sydney Harbour, hence the common name.
