What does coral get eaten by?
When corals are babies floating in the plankton, they can be eaten by many animals. They are less tasty once they settle down and secrete a skeleton, but some fish, worms, snails and sea stars prey on adult corals. Crown-of-thorns sea stars are particularly voracious predators in many parts of the Pacific Ocean.
Which fish eats the most coral?

What saltwater fish eat coral?
Angelfish (Centropyge) The smaller angelfish species work well in larger reef tanks.

Even the smaller (dwarf) angels will occasionally pick at corals in a small tank unless they are well fed.
Why is coral so hard?
The coral species that build reefs are known as hermatypic, or “hard,” corals because they extract calcium carbonate from seawater to create a hard, durable exoskeleton that protects their soft, sac-like bodies. Other species of corals that are not involved in reef building are known as “soft” corals.
