spadefish

Spadefish is a common name for several species of marine fish in the family Ephippidae, known for tall, laterally compressed bodies and vertical banding. The best known is the Atlantic spadefish (Chaetodipterus faber); the term also applies to certain Platax species in the Indo-Pacific that are popular in aquariums.

Spadefish have deep, rounded bodies and small mouths. Adults typically show dark vertical bars on a silvery body, while juveniles may be more mottled. Fins are well developed, and body size varies by species, commonly reaching around 25–40 cm.

Spadefish inhabit warm coastal waters worldwide, frequenting reefs, seagrass beds, mangroves, and artificial structures. They often form schools, especially as juveniles, and group movements are influenced by feeding opportunities and tides.

They are omnivorous, feeding on small invertebrates, crustaceans, zooplankton, and sometimes algae. They forage near the surface and along the bottom, relying on schooling for predator avoidance.

Spawning is broadcast, with eggs and planktonic larvae. Reproduction typically occurs in warmer months, and juveniles disperse before settling into adults.

Spadefish are valued by recreational fishers and, in some regions, kept in public aquariums. They do not show widespread conservation concern, but habitat loss and local fishing pressure can affect populations, leading to regional management measures such as size or bag limits.
