Caribbean reef sharks primarily feed on a variety of fish, including reef fish, groupers, and snappers. They also consume crustaceans, octopuses, and occasionally small sharks and rays. Their diet is diverse and largely dependent on what is available in their habitat.

Sea anenomes, Coral, Clown fish, eels such as the Moray, Groupers (AKA Sea Bass), and Reef sharks live in the coral reef zone.
The largest fish in the Great Barrier Reef is the whale shark. These gentle giants can grow up to 40 feet in length and are filter feeders, primarily consuming plankton and small fish. They are often spotted in the waters of the Great Barrier Reef during their annual migrations.
Depends on the size of the grouper, and species. Reef grouper or giant grouper. Reef groupers are eaten by larger fish like sharks, eels, and rays. Giant grouper can grow to 8 feet and they are eaten by sharks.
There are many fish species that live on coral reefs. The Greater Caribbean region alone there are 500-600 species of coral reef fish recognized, other areas are even higher. Some coral reef fish are Parrotfishes, Surgeonfishes, Rabbitfishes, Dameslfishes, Open Water Plankton Feeders, Benthic Planktivores, Nocturnal Planktivores, Butterflyfishes, Triggerfishes, Grunts, Snappers, Pursuing Predator Fish, Stalking Predator Fish, and Ambush Predator Fish.
