For an LPS-dominant tank, our pick is Coral Frenzy. Coral Frenzy contains 5 total ingredients. By keeping it simple, this product reduces waste creation in your tank. It has natural phytoplankton and zooplankton plus an Atlantic white fish protein.

What’s the Difference between LPS and SPS corals?

Time for a coral education lesson. The basic subdivision of corals is hard and soft corals. Hard corals are named as such because they build a hard skeleton as they grow. When they die, the skeleton is left behind and helps build up the reef height. The hard skeletons create the scaffolding for future coral growth. Over time, the skeletons eventually become rock, which helps create live rock.

On the other end of the scale, soft corals do not leave skeletons behind when they die. They simply shrivel up and disappear.

Hard corals can be further divided into LPS and SPS corals. LPS means “Large Polyp Stony” and SPS means “Small Polyp Stony”. LPS corals are usually large and have bodies that inflate with water, hiding the skeleton underneath. Examples include Hammer and Bubble corals. LPS corals are very popular in the aquarium trade and can glow fluorescence under blue LED lights.

SPS corals are often branched or swirling-shaped masterpieces. They have thin skin covering their skeleton so you’re more able to directly see their shape. SPS corals need bright light, strong water movement, and are generally quite difficult to keep, even for the most experienced reefkeeper. Perfect water quality at all times is a requirement so be prepared to simultaneously manage temperature, salinity, KH, Calcium, Magnesium, Potassium, Nitrate and Phosphate. In other words, good luck! Examples of SPS corals include Montipora and Seriatopora.

Do I Need to Feed My Coral?

Corals receive a good amount of nutrition from the photosynthesis of light; however, this doesn’t necessarily mean it is sufficient, especially for large corals. For example, larger polyp coral frags often consume plankton or krill. By experimenting and adding a mixture of organisms to your tank, you can more closely replicate their wild habitat and keep them healthy. When feeding coral, we suggest turning your tank water flow to low speed or off completely, which will make it easier for your corals to feed. You will also need to make sure your reef salt is a good selection for your coral.

How Often Should You Feed Coral?

The answer will be slightly dependent on the type of coral you’re keeping, but we generally recommend feeding photosynthetic coral 1-2 times per week. The best time of day for feeding is in the evening after the aquarium lights have been turned off for the day.

For non-photosynthetic corals, Gorgonians, or Sea Fans, feed them much more frequently. Because they’re not photosynthesizing their energy, these corals rely heavily on food for energy.

How and What Does Coral Eat?

Coral is cool. Reef-building corals work together in a symbiotic relationship with algae called zooxanthellae. Algae live in the coral polyps and use sunlight to make sugar, which the coral can use for energy. In their part of the deal, the coral provides carbon dioxide and a protective home for the algae. Everyone is happy in the end.

However, this isn’t the only way the corals get energy. Corals also catch tiny floating animals in the water known as zooplankton. They hunt at night when polyps come out of the skeletons, stretching their tentacles into the water to catch any animals that float nearby. The polyps wrap their tentacles around the animals and pull them into their mouths. Stealthy little hunters, right?

How to Feed Coral?

There are three main methods of feeding coral: Zooxanthellae algae, direct feeding, and indirect feeding.

Zooxanthellae algae corals develop vivid colors. These algae feed coral via photosynthesis and create energy from sugar created from light. Because each coral species has different light requirements, Zooxanthellae algae might provide sufficient food for some species, while other species might need feeding supplementation.

Direct feeding is what it sounds like – the coral draws food directly from the surrounding waters. Two clues if your coral is a direct feeder – large tentacles and/or a visible mouth. Examples of direct feeding corals include Open Brain, Elegance, and Plate Corals. Direct feeding corals eat a range of foods, including small diced fish, krill, small pieces of shrimp, plankton, or phytoplankton. Be careful with overfeeding when doing direct feedings, as it can spike your nitrates, which can spell trouble down the line for your corals.

Indirect feeding occurs when corals ingest dissolved organic chemicals via the water without being directly fed as the examples above. Favorite coral foods include waste products and uneaten fish food.

Because there are three ways to feed the coral, the advice here is to know your coral. What species of coral do you have? Learn about how they best consume nutrients, what their ideal feeding schedule is, and more. Try to group corals with similar feeding requirements so you’re not inadvertently under or overfeeding your reef tank. Overfeeding can be linked to water parameter issues so keep an eye on your tank with regular water testing. You might want to consider purchasing a protein skimmer to help remove any unwanted food.

Polyplab – Reef-Roids – Coral Food For Faster Growing 

Although originally engineered for feeding the Goniopora genus of coral, Reef-Roids are a popular coral food source for all filter-feeding corals. Reef-Roids include natural marine plankton and zooplankton and does not include processed fish meals that can rapidly degrade water quality.

Poseidon’s Feast :: Live Marine Copepods – 3000+ Tisbe & Tigriopus Pods 

Poseidon’s Feast is an excellent choice if you’re seeding a new aquarium environment or if your current tank needs a boost. It contains adult and juvenile copepods, a small crustacean (species Tigriopus californicus and Tisbe biminiensis) that fish and corals love to snack on. The adults will be consumed first, as they’re visible to fish and corals, while the juveniles make their way into the rocks, macro algae, and sponges where they will consume detritus and start to reproduce. This means you can develop a healthy copepod population over time.

Tigriopus californicus is rich in omega-3 fatty and amino acids. Tisbe biminiensis are smaller and live in small cracks. They help keep your aquarium clean and keep any fish you have in with your coral entertained as they hunt for these copepods around every crevasse in your tank. This product is great for feeding finicky fish & inverts such as Mandarins, Seahorses, Anthias, Wrasses, SPS, LPS & NPS Corals, Clams, and most other filter-feeding inverts.
