Lo uspi -
Primarily known from the Fiji region and a few reported sightings from New Caledonia. The almost identical Siganus nigerfrom neighbouring Tonga differs in having a black tail and was described from two specimens only. Adults of both S.uspiand S.niger live in identical habitats, and are usually found in pairs along edges of shallow drop-offs and in deep depressions on reef crests where they feed on fleshy algae. They are readily identified by their nearly  black colour and yellow pectoral fins. Only S.uspi has a yellow tail. Length to 24cm.
