The Importance of Coral Nutrition in a Reef Tank
Feeding corals might seem straightforward, but if you're new to the world of reef tanks, understanding coral nutrition is key to fostering a healthy, thriving environment. Unlike traditional fish, corals require a mix of nutrients, light, and water flow to stay vibrant. This beginner’s guide will walk you through the essential aspects of feeding corals and ensure that your reef tank flourishes.
Do All Corals Need to Be Fed? Photosynthesis vs. Feeding
Most corals have the ability to perform photosynthesis, meaning they can produce some of their own nutrients by using light. However, not all corals are self-sufficient, and many rely on direct feeding to thrive.
-
Photosynthetic Corals: Soft corals, SPS (Small Polyp Stony) corals, and some LPS (Large Polyp Stony) corals primarily get their energy from light. These corals typically need less direct feeding but still benefit from occasional reef food supplements.
-
Non-Photosynthetic Corals: Corals like Gorgonians and certain SPS species depend on external nutrients from zooplankton and phytoplankton.
Understanding Basic Coral Nutrition Needs
Corals require a balanced mix of nutrients to grow, color up, and stay healthy. These nutrients generally come from zooplankton, phytoplankton, and dissolved organic matter in the water. While corals do get some nutrition from the environment, feeding corals directly can significantly improve their health and growth.
-
Amino Acids: These are essential for coral tissue repair and growth.
-
Trace Elements: These help corals develop their skeletons and promote overall health.
-
Fatty Acids: Crucial for coral immune systems.
Common Types of Coral Food Available (Liquid, Powder, Pellets, Frozen)
There are a variety of coral food options available, each with its pros and cons depending on your coral types.
-
Liquid Coral Food: Ideal for corals that feed on fine particulates like zoanthids or mushrooms. Easy to disperse and absorbed quickly.
-
Powdered Coral Food: This can be suspended in water and is perfect for LPS corals that require larger food particles.
-
Pellets: Great for SPS corals that prefer a steady food supply. Choose slow-dissolving pellets to avoid polluting the tank.
-
Frozen Coral Food: Highly nutritious, but requires thawing before feeding. Perfect for meaty corals like torch and hammer corals.
How Often Should Beginners Feed Their Corals?
As a beginner reef keeper, it’s important not to overfeed your corals. Overfeeding can lead to poor water quality, which is harmful to both the corals and the overall reef environment.
-
For photosynthetic corals, feeding once or twice a week is usually sufficient.
-
Non-photosynthetic corals may require more frequent feeding, possibly every 2–3 days, depending on the species.
Simple Feeding Methods: Broadcast vs. Target Feeding Basics
Two primary methods exist for feeding corals: broadcast feeding and target feeding.
-
Broadcast Feeding: This involves scattering food throughout the tank. It’s best for corals that feed on small particles suspended in water, like zoanthids and soft corals.
-
Target Feeding: Involves delivering food directly to specific corals. This method is especially effective for LPS corals and larger species like torch or frogspawn.
Signs Your Corals Are Hungry (or Getting Enough Food)
How can you tell if your corals are properly fed? Here are some signs to look out for:
-
Extended Polyps: When corals are hungry, their polyps may extend to catch more food. If you notice the polyps staying retracted, they may not be getting enough nutrients.
-
Color Fading: Lack of proper feeding can lead to color loss, as corals are unable to synthesize the necessary compounds for vibrant pigmentation.
Choosing Your First Coral Food: What to Look For
As a beginner, you should look for all-in-one coral foods that cater to a variety of coral types. These often contain phytoplankton, zooplankton, and other essential nutrients like amino acids and fatty acids.

Impact of Feeding on Reef Tank Water Quality
Feeding corals can affect your reef tank's water quality. Overfeeding can lead to excess food decomposing, resulting in an increase in nitrates and phosphates. To avoid this, ensure you feed small amounts and remove any uneaten food promptly.
Common Mistakes Beginner Reef Keepers Make When Feeding
Beginners often make these mistakes when feeding corals:
-
Overfeeding: This can harm your reef’s water quality and lead to algae blooms.
-
Inconsistent Feeding: Skipping feeding sessions can lead to poor coral health.
-
Using Inappropriate Food: Different corals require different types of food. Choosing the wrong food can result in poor nutrition.
Best Coral Foods for a Thriving Reef Tank
Feeding corals is a delicate balance. By understanding their nutritional needs and using the right types of food, you can ensure your reef tank thrives. Regular feeding schedules, proper food types, and mindful practices will promote the growth and health of your corals.
