Girdled Scalyfin
Parma unifasciata
The Girdled Scalyfin (Parma unifasciata) is a small Australian reef damselfish noted for its bold banding and algae-grazing habits. It is not a common angling target; most encounters are by divers around shallow temperate reefs.
Identification points
- Dark vertical band immediately behind the head, giving a girdled look
- Deep, laterally compressed damselfish body with a continuous spiny dorsal fin
- Pale to dark scaly-looking body pattern with a contrasting tail and fin margins
Habitat
Shallow temperate rocky reefs and kelp-covered areas, especially in coastal waters around southern and southeastern Australia; adults stay close to reef structure and algal growth.
Bait notes
Not a regular game fish. If targeted for observation or incidental capture, very small natural baits such as shrimp fragments or tiny marine worms are more relevant than standard sportfishing lures.
Behavior
A territorial reef-associated fish that browses algae and small benthic foods. It tends to remain near shelter in crevices or among seaweed and may defend a small home area.
Caution
Handle carefully; like many reef damselfishes it has sharp dorsal spines and should be released gently. Check local regulations before collecting or retaining reef fish.
Fishing notes
Best encountered by snorkeling or diving rather than fishing. Small hook sizes and very light tackle are required, but catching them is generally discouraged because they are small reef fish and not a standard target species.
