What kind of fish eat coral?

What does Coral benefit from fish?
Because of the diversity of life found in the habitats created by corals, reefs are often called the “rainforests of the sea.” About 25% of the ocean’s fish depend on healthy coral reefs.

Does coral need fish?
Coral reefs are an important resource for large-bodied fish in the Caribbean. They use the reef for shelter during the day, and as a hunting ground by night. Recent studies have shown that coral reefs rely on fish, too. Fish excrete ammonium, an essential nutrient for coral growth, through their gills.
