What is the Best Food for Corals?

Already we have discussed 5 foods that are best for corals. But if you want a specific one then we would choose Coral Frenzy for some obvious reasons.

Your tank requires a lot of things and the coral Frenzy comes with all the required ingredients that any tank requires. It’s like vitamins that human needs. We need a balanced ratio of all the vitamins and our regular food doesn’t contain all of the needed vitamins. That is why people go for multi-vitamin tabs or capsules where they have all kind of needed vitamins for the human.

So Coral Frenzy is kind of the same thing that is formulated to feed all organisms in your tank. This one is actually the best choice for newcomers as it will help them to maintain a balanced nutrient level in the tank.

As I said earlier, Coral Frenzy is formulated to feed maximum organisms of the tank so there is less chance of uneaten food floating on the water. On the other hand, it helps a lot to keep the entire tank clean which is really important not only for corals but also for all the inhabitants in the tank.

What are the Types of Corals?

Mainly there are two types of corals: SPS (Small polyp stony) and LPS (large polyp stony). Both types of corals are similar to each other but there are some big differences too.

Let’s take a closer look at them:

SPS Corals: These corals have little polyps on the stony skeletal base and they generally resemble flowers. Small polyp stony corals need a strong current of high-quality water and they are open to negative nitrate effects. It would be very tough to grow an SPS coral with no adequate bright light. They are of calm nature.

LPS Corals: On the other hand, these corals come with large fleshy polyps and strong skeleton base. LPS corals need a medium to high light level to develop nicely and move with the currents of water.

Large polyp stony corals are also well known because of their ability to sting. They are really aggressive and will sweep up other corals from their area. Overall, they are not friendly to their neighbor.

In order to choose the best food for both type of corals, there are a lot of things that should be taken into account. Though both of them rely on the same nutrients, the way they get their foods are very different.

Large polyp stony corals are way more aggressive than the small polyp stony corals, so you would want to give food in a way so that both of them can get to eat the food equally.

On the other hand, how much are you feeding them also matters. An excessive amount of wrong foods will cause long-term issues for both your coral and other marine inhabitants sharing the same tank.

Foods that we have reviewed earlier are perfectly fine for both corals. However, make sure you feed them in a limited amount and be aware of the LPS corals.

What Else Coral Eats?

All kind of corals mostly relies on the phytoplankton. Phytoplankton is generally very small, sometimes even microscopic. Corals also eat organisms that move slow and easy to hunt such as floating plankton or larvae.

Some corals also eat zooplankton but sometimes they are tough to catch for SPS corals. LPS corals don’t struggle much to hunt down floating zooplankton.

Bacterioplankton is another great source of nutrients. They are also known as reef snow. Bacterioplankton contains bacteria. Some bacteria are free-living and some are associated with different materials in the water. All corals feed Bacterioplankton heavily.

Another thing that corals eat are the dissolved organic materials in the water. Corals absorb these DOM (dissolved organic materials) by their cell membrane. Corals which has large polyps (LPS) can catch and eat large items such as small fishes.

On the other hand, soft coral decides their food by the size. LPS corals can easily capture and eat moving items as they are more aggressive compared to the SPS.

How Does Coral Eat?

Corals need signals to get ready to eat. The signal can be anything:

  • Light change
  • Temperature change.
  • Oxygen level change.
  • Movement in water.

All the above-listed things give coral the signal that it’s time to eat. These signals go to corals’ roots and notify them of the increasing amount of plankton in the surrounding area.

In the ocean, coral eats once the sun goes down. And planktons also come out when the light fades. So when the light goes off corals open their polyps and starts ingesting planktons that cross their way.

Light plays a very important role for corals to grow and thrive. To know more you can read our article on best LED reef lights.

The barbs of the coral kill any plankton that comes in contact with them. Once plankton is killed, the tiny tentacles pull that into the coral’s mouth.

Moreover, corals use stringers in order to draw foods towards them like sea anemones and jellyfish. During the day, corals hide their tentacles inside the skeletons. Once they get a signal, the tentacles come out and ingest any plankton that comes in contact.

By now you might have guessed how hard is it to feed corals. Feeding fishes are way too easy. However, different types of corals require different treatments. Once you spend some time with them you’ll get to know how they should be fed.

How to Feed Corals?

Just dropping the right amount of pellet or flakes is all you would need to do for feeding fishes but in the case of corals, it’s much more complicated. You still need to know about your corals and what they need to develop, even though most coral foods come with all nutrients.

If you don’t know what the corals would eat and what is the proper amount, then you will see uneaten food floating on the water. Uneaten food lessens the nutrient level and it is harmful to all the creatures in the tank.

There are two types of famous methods to feed corals. We have broken them down below:

Broadcast Feeding:

In this method, with the help of the current from the pump or in any other way you would stir up the water and dispel the coral food so that the food can spread throughout the entire tank evenly. Broadcast feeding is very famous.

As the food spreads in the entire tank, it also nourishes the fishes. But in this method, it is highly important to keep in mind that, you should feed the coral the right food and in the right amount. Broadcast feeding method is an uncontrolled way of feeding corals, so it is easy to make mistake by giving too much food which will be a threat to the entire tank.

Target Feeding:

In this method, you’ll need a syringe or something similar which will be used to deliver the food directly to the corals. That means, food will not be all over the tank, it will be only there where you want it to be. Target feeding method can be a great way for keeping the water healthy.

If you have fish or any other creature in the fish tank, then you would need to feed them separately. Another thing that you should know is, target feeding method will be a great option for Large polyp stony corals, as they are very aggressive.

On the other hand, the broadcast method will be perfect for calm natured corals like small polyp stony. It is because the food will be all around the tank which makes it easier for non-aggressive corals to eat food from anywhere.

Importance of Corals

We know corals look very pleasing but there are very few who know the importance of corals. In recent days, corals have suffered really hard due to some changes such as global warming, polluted waters, overfishing etc. To save corals, first, we’ll need to know why they are so important.

Here are why corals are so important:

  1. Whether it is small fish or the large ones, all of them find both food and shelter in the corals. Without corals, sea life will come to an end within no time.
  2. Corals are the natural water filters. Most of the corals and sponges ingest particles from the ocean which enhances the clarity of the water. Ever thought why some sea water looks so crystal clear? Corals and sponges are one of the reasons.
  3. Moreover, coral reef protects the coast from strong waves and currents. What they do is, they slow down the water flow. One interesting thing about coral reefs are, they incline from where there is strong wave pressure or currents.
  4. When it comes down to fish tanks. Corals will also help to keep the aquarium water fresh and clean. They will consume most of the fish waste and fishes on the tank will use these corals as a nursery ground. Sometimes fishes find food on the coral reefs too. And lastly, a fish tank filled with coral reefs looks immensely beautiful.

Final Words

Growing and maintaining a tank of corals is not as easy as growing fishes. Fishes don’t require a lot of your time, just give them food and keep the water clean and that’ll be all.

But in the case of corals, as I have said you’ll have to take care of a lot of things. From their food to keeping the water well balanced, all require a lot of skills.
