Nassau groupers are most commonly found in shallow water reefs, both natural and artificial. While they have been recorded at depths up to 100 m, they are more prolific in depths above 30 m. Nassau groupers can also be found in beds of sea grasses and prefer areas of high visibility. Late juveniles to young adults prefer corals with large macroalgal populations. This species is also euryhaline, meaning it can tolerate a wide range of salinities. During spawning, Nassau groupers can be found meters offshore, which has in part led to their exploitation and subsequent placement on the IUCN Red List.
