What does coral eat in their natural habitat?
We all know that corals are widely dependent on the light to survive. However, there are various foods that corals also feed themselves into so that they can provide the nutrients that their body needs. Here are the most common foods that corals consume in their natural habitat.
Water-borne plants or algae. Most of the coral consume water-borne plants such as algae, phytoplankton, invertebrate larvae, floating plankton, and detritus. These water-borne plants provide the nutrients that the corals need to survive. Bacterioplankton, which consists of free-living bacteria is also one of the primary sources of foods for corals. Pseudoplankton, on the other hand, is made out of floating eggs, detritus, and other materials.
Smaller fishes. You may be surprised, but there is some coral eating fish out there. These corals are huge that obviously have larger polyps as well. Best examples of these kinds of corals are the Catalaphyllia and Cynarina. Most corals will depend on the size of the food that they are going to eat rather than the composition or nutrients that they can get.

Coral-eating nudibranch. Another one is the nudibranch. Coral-eating nudibranch such as Phestilla can wipe out up to 10 square inches in just a single day. You will know if there is nudibranch existence in your tank because of the poor coral polyp expansion and discoloration of the reefs as well. Always keep in mind that corals that had been attacked by the nudibranchs will only last for a couple of days before it will completely die. Therefore, if you notice some bare skeletons in the patches, you might want to scrutinize it because there could be nudibranch existing that you do not even know and the females will soon start invading your tank by spreading hundreds of eggs in just a single day.
