  • SizeUp to 30 cm total length, commonly 15 to 22 cm.
  • Social HabitHighly gregarious, forming large, fast-moving schools in midwater above rocky reefs and along walls.
  • HabitatRocky reefs, drop-offs, and open water near structures. One of the most common schooling fish on Mediterranean reefs.
  • Depth1 to 70 m, most common between 3 and 30 m.
  • Feeds OnZooplankton, algae, and small invertebrates. Feeds both in midwater and near the substrate.
  • DistributionEastern Atlantic from the Bay of Biscay to South Africa, including the entire Mediterranean Sea.
  • DescriptionOne of the most commonly seen schooling seabream on Mediterranean dives. Large, fast-moving schools patrol reef edges and walls, their silver bodies flashing in the light. The dark spot on the tail and the band across the forehead make identification straightforward. A familiar and welcome sight on any Mediterranean reef dive.
