Golden trevallies are among the most popular fish for divers who are lucky enough to be able to explore the tropical deep-sea islands.

The spawning period is in late spring. Sexual maturity in females is estimated at 32.5 cm. Juveniles may move among the filaments of jellyfish or travel with larger animals, thus benefiting from protection.

Larger specimens may be found with groupers and sharks. At sea, these trevallies also follow divers.

Prized for its meat, it is now a species raised in aquaculture.
