Corals are living organisms that need proper nutrition in order to reach their full potential. Unfortunately, people often overlook this aspect when caring for their corals and doing so can seriously harm them. Just as feeding different types of fish, some coral types have different needs than do others. Corals have adapted to capture falling food, and even varieties that are highly reliant on light can benefit from being fed.

How Light “Feeds” Corals

Zooxanthellae algae that lives within coral bodies provides the specimen with energy via photosynthesis. Some varieties, such as SPS corals, are highly dependent on this energy source. In addition to providing a food source for the coral, this Zooxanthellae algae is also responsible for the vibrant colors of the specimen. Make sure you pay attention to the lighting needs of each coral and supply them accordingly.

Feeding Corals Directly

Most corals appreciate being fed a supplemental diet in addition to their usual energy from photosynthesis. LPS corals usually have more of an appetite for larger prey that can include small diced small fish such as thawed frozen plankton, phytoplankton, krill, or even pieces of shrimp. Additionally, there are foods made specifically for each type of coral that can be purchased online. It is important to experiment and figure out what works best for your coral variety.

Feeding Corals Indirectly

Another method of feeding corals involves keeping other organisms in your tank alongside them. Fish and microfauna digest and release organic compounds in which corals can feed on. Many coral lovers keep fish in their tank for this very reason. If your tank size permits, fish make a great addition to your thriving aquatic ecosystem. Additionally, small scraps of food and bacteria tend to make their way into coral’s diet, only benefiting them more.
