As its standard name would suggest, the Ring-tail Cardinalfish has a distinct black band around the caudal peduncle.
Adult Ring-tail Cardinalfish are grey-orange above and yellow to golden below. They have iridescent blue lines from the snout through the eyes, and a distinct black band around the caudal peduncle.
The species is most commonly found in rocky and coral reefs.
Occurs throughout the Indo-West Pacific.
In Australia it is recorded from south-western Western Australia, around the tropical north and south to the central coastline of New South Wales.
