Care
Tank: This fish outgrows home aquaria and is only suitable for public-aquarium-sized systems; no home tank size is given. It reaches 125 cm (commonly about 84 cm) and over 24 kg. Water: the sources give no species-specific figures, so the values here are general marine aquarium guidance: 24–27 °C, pH 8.1–8.4 and specific gravity 1.020–1.025. Keep nitrate low and the water well oxygenated. Behaviour: a wide-ranging predator. Juveniles mimic the poisonous Valentin’s sharpnose puffer, and are the form usually sold. Identification: adults are pale with dark saddles and blue spots; juveniles are white with black saddles and yellow fins like the puffer they copy. Trade and status: a prized food fish, increasingly important in the live reef food fish trade, and linked to many ciguatera poisoning cases. IUCN: Least Concern. Selling: our policies require the adult size and long-term tank needs to be stated clearly in the listing. Large fish must travel by a specialist live-animal courier (see the Livestock shipping guide).

Diet
Adults eat large reef fish, including other groupers; juveniles take smaller fish, crustaceans and squid. In captivity it needs large pieces of fish and squid.
Breeding
A protogynous hermaphrodite: males develop from mature females, which mature at about two years. Forms spawning aggregations. Not bred in home aquaria.
Compatibility and tank mates
Not reef safe and will eat other fish, including other groupers. Only for very large public-aquarium systems.
