  • 8 or 9 orange stripes on sides

Colour:

Pale brown with 8 or 9 orange stripes on sides.

Size:

Up to 40 cm TL.

Distribution:

Indo-West Pacific in tropical waters.

Habitat:

Coral reefs in sheltered lagoons and outer reef slopes, also in turbid waters. Adults are found from the surface to at least 35 m depth.

Biology:

Feeds on fishes, crustaceans and cephalopods. Often found in schools of 20 to 30 individuals. On the Great Barrier Reef males grew faster, were significantly longer than females of a similar age, and grew larger overall size.1 Females matured at an average age of 2 years, corresponding to 19 cm FL.2 Spanish flag are a multiple spawner, spawning from October through to December, coinciding with a new moon on the Great Barrier Reef.2 This species is characterised by a long life span, slow growth and a low mortality rate. Estimated maximum age is 20 years, corresponding to 33.5 cm FL.1

Fisheries:

Caught with handlines, traps, gill nets and trawls.
