It is a long-lived and slow-growing species which reaches maturity at 8–9 years, and the oldest recorded individual is 56.
These fishes are carnivorous, mostly feeding on other fishes, crustaceans and molluscs.

Adult snappers often form large schools on the outer reefs or above sandy areas, mainly to form spawning aggregations.
Small brownish juveniles mimic damselfishes of the genus Chromis in order to approach their preys.

The chambered nautilus, Nautilus pompilius, is known to scavenge deceased snappers.
A pair of nautiluses recorded feeding on a snapper at 703 metres below the surface constitutes the deepest recorded sighting of any nautilus species.
