The Harlequin Grouper, sometimes called the Harlequin Hind, is a large and aggressive carnivore that should only be kept with fish of a similar disposition. It will do well on a diet of krill, frozen silversides, and other chunky frozen food. It will eat smaller fish it can catch as well as most invertebrates, so it is not recommended in any sort of reef aquarium. It will not eat corals, but it may knock them over due to its large size.

Approximate arrival size for Harlequin Grouper: Small: 2 to 3 inches; Medium: 3 to 5 inches; Large 5 to 6 inches
