It’s quite easy to find fish food, regardless of whether your fish are freshwater or marine fish. However, when it comes to coral, many of us tend to ignore their needs. The truth is coral has a very specific diet and can even die without food.

Therefore, you must choose the best coral food for their healthy growth. You must also keep an eye on the nutritional value of the coral food that you give them.

There is a lot to learn when it comes to coral food and nutrition.

So, let’s delve deeper into this in-depth coral food guide today!

Coral 101: The Biology of Coral

Let’s cover the basics first.

When I first saw coral when I was visiting tropical seashores, I thought, “Oh look, pretty rocks!”

I bet most of you guys thought the same when you first saw them too.

But that’s not the case, as you know, because coral are alive and they are animals. To be more precise, a coral is a colony of thousands of miniature animals which are called coral polyps.

These animals are distant cousins of jellyfish and anemone.

The size of a coral varies. It can be as small as a pinhead or as large as a basketball. I will talk more about their size and classification later on.

But how can small animals form a solid rock formation?

The coral polyps sit on hard rocky shells and form the skeleton. These skeletons are called calicles, and this is the part we mostly notice.

The body of a coral polyp consists of 4 major parts:

  1. Mouth
  2. Saclike body
  3. Tentacles which sting
  4. Calicles

Polyps use the mouth to collect different minerals and secrete the deposits in order to construct a calcium carbonate skeleton underneath. The mouth also consumes food.

The tentacles are mainly the protection unit of the polyps so that different animals can’t harm them. The body also houses other important micro organs. 

Now we’ve come to the important topic – how do coral eat?

In nature, 95% of their total food comes from algae called zooxanthellae. These algae are the main food suppliers of coral. In addition, polyps consume different zooplankton.

A symbiotic relationship can be seen here.

The zooxanthellae provide oxygen, sugar, and essential fats to the polyps. In return, the polyps offer them CO2, phosphorus, and nitrogen. Additionally, the polyps protect the zooxanthellae with their hard shells.

Do you know that coral are basically translucent? It means that they don’t have any color of their own. The vibrant colors come from the zooxanthellae. If coral fall victim to any kind of environmental threat, they release zooxanthellae and die out.

This phenomenon is known as coral bleaching.

 7 Best Coral Foods 2020

1. POLYPLAB – Reef-Roids – Overall Best

POLYPLAB - Reef-Roids

POLYPLAB – Reef-Roids is certainly one of the superior coral foods on the market. This is mainly because it is a special, coral-only food.

Unlike many other coral food manufacturers, they haven’t used processed fish meals. Therefore, coral will not have to fight with the fish for food.

One of the key features of the POLYPLAB Reef-Roids is that the grain size of this food ranges from 150 to 200 microns. This is the perfect size for coral food as the plankton in the ocean tends to be of a similar grain size.

Give it a little bit of a stir, and the mixture will dissolve in the water in no time. It’s better to use the target feeding method for better usage.

Key Ingredients: marine plankton

2. Coral Frenzy Powder Formula with Probiotics – Best Coral Food for Beginners

Coral Frenzy Powder Formula with Probiotics

Coral Frenzy is the most popular, if not the best, coral food on the market. The popularity of this coral food is mostly due to the ease of use.

If you have just started out with a reef tank, I personally recommend that you use Coral Frenzy.

Why is that?

Coral Frenzy is the solution to all your reef tank food requirements. It’s a dried food which fish, coral, and plankton can enjoy.

The particle size of this food is between 53 to 1700 microns., so the coral will get smaller grains, and the fish can enjoy larger grains.

Another factor which I love about Coral Frenzy is that all the ingredients are written on the packaging label. There are no hidden ingredients, so you can be aware of everything which you are putting into your tank

You should stick to the broadcast feeding method with this food.

But make sure to use only a small amount of food initially. Also, turn off the skimmer when feeding.

Key Ingredients: fish protein, oyster larvae, salmon roe, dunaliella salina, schizochitrium, rotifers, copepods, daphnia, spirulina, and haematococcus pluvialis

What Types of Coral Are There?

As you are aware, coral are the skeletons of coral polyps. However, not all coral polyps are the same.

There are two types of coral polyps : 

  • SPS coral (small polyps stony)
  • LPS coral (large polyps stony)

Yes, size is the key differentiator between these, but there are some significant other differences between them.

SPS coral (small polyps stony)

Firstly, these coral are made of smaller polyps which somehow mimic the appearance of a flower. They live on the upper level in the sea as they demand strong current and bright sunlight in order to grow.

They are quite friendly compared to the LPS and will colonize easily with other species.

However, they can’t stand nitrates and will suffer greatly if the nitrate level in the water is high.

Naturally, they depend on zooxanthellae for food and, in return, offer them food and safety.

LPS coral (large polyps stony)

As the name suggests, LPS is the larger variant. It has a large fleshy body which can be as large as a basketball.

Unlike the SPS, they prefer living in the depths of the water and move along with the current flow.  

They also demand sunlight, but not as much as the smaller coral. LPS can thrive even in medium sunlight.

The biggest difference between SPS and LPS is hostility. The LPS are quite hostile and sting their neighbors in order to gain territorial advantage.

When it comes to food, LPS and SPS tend to have similar food habits. If you want to keep LPS in your aquarium, make sure to offer them an ample amount of food, otherwise they will show hostility and attack other members in the aquarium.

What Does Coral Eat?

Firstly, they will not eat your precious fish!

Regardless of type, coral have only two things in their food habits:

  • Phytoplankton
  • Zooplankton

Phytoplankton is a miniature plant. It can be microscopic in size. Mostly, phytoplankton in the coral diet consists of different kinds of algae.

Similarly, zooplankton is a small microscopic animal. As zooplankton are self-propelling, SPS coral find it difficult to catch. However, it’s very easy for LPS coral.

But both the SPS and LPS coral love zooplankton as well.

As well as phytoplankton and zooplankton, coral also eat bacterioplankton. Some people prefer to call this reef snow.

Also, you can use dissolved organic food material for your coral.

How Do You Feed Coral?

Most commercial coral food comes in flakes or pellets. Only a few come in liquid form which dissolves in the water. Therefore, some people believe that tossing flakes or pellets in the water is all it takes. So, from that point of view, liquid coral food is better to use.

However, the process of feeding coral is a bit more complex than feeding flakes to your fish.

Unlike fish, coral have a hard time identifying what is and what isn’t food. That’s why, if you pour in food, coral might not consume it. This leads to an increase in waste food in the tank, and eventually, an increase in nitrates.

There are two popular methods for feeding coral:

  • Broadcast feeding
  • Target feeding

Broadcast Feeding

The basic concept of broadcast feeding is spreading the grains of food throughout a large area, creating waves. You will need a pump or similar device which stirs the water.

You must place a pump in the tank and turn it on to create waves. Now, pour flakes or pellets in front of the waves. The waves will carry the grains to the coral.

As you can imagine, you will have less control in this process as a large amount of food will still remain uneaten. It’s better to use all-purpose food which both coral and fish can eat, otherwise you will end up with a lot of uneaten food in the tank.  

Target Feeding

The second method is the target feeding method. This method is more controlled, and there is less chance of food going to waste.

You will need a syringe or similar tools for this method. You must create a food mix and put it in a syringe. Then, you can deliver the food directly to the coral’s mouth.

This process is a bit time consuming, but it will help you maintain better water quality.

So, which method should you use?

Well, there is a simple strategy which you can use here. If you have LPS coral in your tank, you should use the target feeding method. As LPS are more aggressive, they will get an ample amount of food and will not agitate other species in the tank.

If you have SPS coral in your tank, you can stick to the broadcast method. As you will be spreading the food, it will reach tough and narrow cracks. Therefore, all the coral will get enough nourishment.

Conclusion

It’s really hard to rank the best coral foods as all of them serve different purposes, and all of them seem to work very well.

However, just for the sake of ranking, POLYPLAB – Reef-Roids is in first place. Next is Coral Frenzy Powder Formula with Probiotics.

In third place is Red Sea Aquarium Supplement.
