Babies can be eaten by many animals when they are floating in the plankton. Some fish, worms, snails and sea stars prey on adult corals, but they are less tasty once they settle down and make a skeleton. Many parts of the world are home to crown-of-thorns sea stars.
Corals can also be killed by predators such as jellyfish, which eat their skeletons. Jellyfish have been known to eat the skeletons of coral larvae, and they have even been seen eating the skeleton of an adult coral.

Do tropical fish eat coral?
One third of all corallivorous fishes fall into this category because they have an “obligate” association with their coral prey, meaning the majority of their diet is centered on coral. Coral is a measurable part of the diet of other corallivorous fishes. Coral is the most abundant marine animal in the world and is found in all oceans, except for the polar regions.
It is also the largest living animal on the planet, with a body length of up to 2.5 metres (8 feet) and a diameter of about 1 metre (3.2 feet). Coral reefs are home to a wide variety of marine life, including many species of fish, crabs, lobsters, shrimp, octopuses, squid and many others.
What saltwater fish eat corals?
The smaller angelfish species work well in larger reef tanks. The emperor angelfish (Pomacanthus imperator) will eat corals and shrimp and should be avoided. Sometimes the smaller angels will pick at corals in a small tank unless they are handled carefully. Moderately hardy, but not difficult to keep in an established tank.
Do fish eat coral reefs?
Corals are vulnerable to attack in addition to the weather. Fish, marine worms, barnacles, crabs, snails and sea stars all prey on the coral. Coral bleaching is caused by a combination of factors, including high temperatures, high salinity, low oxygen levels, and high levels of ultraviolet radiation. It is the most severe form of coral death and can lead to the death of the entire coral colony.
Do starfish eat coral?
Normally, the starfish contribute to the reef’s diversity by eating coral that are slower growing. At outbreak levels, the starfish are able to eat coral quicker than the coral can grow.
“This is the first time we’ve seen this in the wild, and it’s a big deal,” said study co-author and University of California, Santa Cruz, marine ecologist David Schubert, who was not involved with the study.
Do butterfly fish eat coral?
In their natural habitat the Prognathodes spp. butterflyfishes often prey on soft corals and gorgonians and as such are a significant threat to place in the marine environment. In the wild they are found in tropical and subtropical areas of the Indo-Pacific, the Indian Ocean and the Atlantic Ocean. They are also known to occur in Australia and New Zealand.
Do parrotfish eat coral?
Parrotfish are colorful, tropical creatures that spend about 90% of their day eating algae off coral reefs. The task of cleaning the reefs is performed by this almost-constant eating. In the wild, they are found in tropical and subtropical waters around the world, including the Caribbean, Pacific, Indian, and Atlantic Oceans.
