Identification points

Adult males show vivid blue-green and orange longitudinal stripes with a greenish head
Body is long and slender with a pointed snout and small terminal mouth
Females and juveniles are brownish to reddish with a paler side stripe and less intense patterning

Habitat

Shallow coastal rocky reefs, boulder fields, Posidonia seagrass beds, and algal margins, usually from the surface to about 60 m but most often in clear, sheltered inshore water.

Bait notes

Small natural baits such as ragworms, shrimp, mussel, and pieces of squid work best; very small soft plastics and jigheads can also take fish. Tiny hooks and light terminal tackle are important.

Behavior

An active diurnal forager that picks small crustaceans, mollusks, worms, and other benthic invertebrates from rocks and seagrass. It is territorial, quick to spook, and males are highly colorful during breeding season.

Caution

None notable; it is small and usually not a consumption concern, but follow local size and bag regulations and avoid overfishing nesting or shallow reef areas.

Fishing notes

Fish light line near weed edges, broken rock, and reef holes with a small float or bottom rig. Use a delicate presentation and keep casts short and quiet; this species often needs finesse rather than power fishing.
