It is very difficult to visually sex these fish and they are not known to be bred in captivity.

Tank compatibility[edit]

This fish is not typically reef-compatible as it will see smaller fish and invertebrates as food. However, all fish are slightly different and may not act as predicted.They will not tolerate other Groupers and should only be kept with robust fast-swimming tank mates (so they are not out-competed to food by the Grouper) such as some Tangs, Angelfish, Wrasses and Triggerfish.


This fish has a huge appetite and will eat and eat if given the opportunity to. They prefer a variety of meaty seafood such as shrimp, mussels, cockles, fish fillets, clams and scallops. You can add vitamins and highly unsaturated fatty acids to their diet by soaking freeze-dried krill with supplements such as Zoe and Selcon. They should not be fed feeder fish.

Feeding regime[edit]

Feed once or twice a day.

Environment specifics[edit]

This fish is a heavy waste producer so excellent filtration and a powerful protein skimmer is a must as they are also sensitive to water quality issues.


An active, fast swimming, curious fish that will be aggressive towards others of its own kind, and will bully any newcomers to its territory. They are known to beg for food and are reactive to the goings on outside the tank.


An attractive and striking large fish. The body is mottled and pale in base colour and covered all over, including the fins, with black/brown spots.
