The Best Coral Foods for Rapid Reef Growth in the Aquarium


Saltwater reef aquariums are the epitome of the hobby.

It takes a lot of hard work and dedication, but caring for such a complex ecosystem is highly rewarding.

An initial foray into the research for achieving optimal growth results, however, can lead to a lot of questions.

Would it be best to go for a liquid or pellet coral food?

Further diving into the subject will lead concerns like what nutrient sources do SPS corals need to feed on to thrive?

Do LPS and other soft coral reefs need different nourishment sources?

How about Zoanthids and are they pretentious about their daily sustenance?

All of these are valid and common questions, and it can be difficult to know the right answers.

After spending way too much time experimenting with my own tanks, and with no small advice from friends I think I finally have a bit of a handle on some of the matter.

I think we can narrow most of this down to simply asking one thing.

What are the best LPS or SPS coral foods if fast and healthy reef growth is the aim of your aquarium?

Let’s get to it.

Check out the quick overview table comparing the best of coral foods:

Food name: Type: Recommended for: Price Bracket:
1. Red Sea Reef Energy Liquid Mixed reef aquariums $
2. Reef-Roids Powder-ish SPS dominated reef tanks $
3. Coral Frenzy Pellets LPS corals $$
4. Benereef Powder Mixed reef aquariums $$

What to look for when choosing the right one for your setup?

Before picking out a food supplement you need to be sure you’re purchasing the best one for your corals’ exact needs.

There’s a ton of research I went through when I was first starting out with reef tanks, but the gist of things to look out for can be narrowed down in this buyer guide:

1. Water Degradation

Adding additional nutrients into a closed system can be problematic if it’s not accounted for in the formulation of the feed.

Excessive nutrients may be employed by hair algae, causing an outbreak.

One way to ensure that your coral feed won’t be the cause of this is to check for its effect on water degradation:

Look for foods that, at the very least, give recommendations on how to handle excess nutrients in the water. This becomes more of an issue with foods that are designed for non-targeted feeding. Such products handle an array of coral types and aquatic life, but excess food is excess food. If the supplements go uneaten, then problems with a surplus of nutrients can arise.

The responsible manufacturers out there do their research and extensive testing before releasing a product on the market.

I made sure to review foods that are safe upon usage that follows the directions.

As it turns out it’s all about the balance.

2. Liquid VS Pellet Foods

Using the wrong type of food on a coral colony is a one-way ticket to fish tank problems and poor results.

Make sure you know the kind of coral a product caters to when deciding between liquid vs pellet foods:

Pellets provide a lot of condensed nutrients that can be targeted directly at the coral colony you wish to feed. However, the size of pellets limits this to mostly LPS corals as their mouths are larger. Liquid foods work well on both types and even some types of fish but tend to dilute quickly within the water column. This makes it harder to target-feed the hungrier LPS corals with a liquid form of nutrition without creating a nutrient-dense environment in your aquarium.

It has been my experience that having an LPS-dominant coral reef aquarium will benefit the most of larger particle foods such as pellets.

If you’re looking after a fairly mixed reef then feeding liquid foods may be the better option.

I will explicitly mention which brand is best for which setup in my reviews below for your convenience.

3. Broadcasted or Targeted

Coral food tends to be designed for a specific type of feeding, even if instructions exist for both types.

Be sure to check whether a food is meant to be broadcasted or targeted for optimal results.

Here’s what you should know:

Coral foods designed for broadcast feeding usually dilute through the water table, aiming to feed all of the denizens of an aquarium. Targeted foods, on the other hand, are best fed directly to the coral through a syringe, directly falling down on it, or through other similar mechanisms. The broadcasting method is easier, though overfeeding risks are increased while targeting takes a lot more hands-on effort.

Note that “increased risk of” does not imply that it will certainly happen.

Foods meant to be broadcast-fed are great for reef aquarium owners who don’t want to spend too much time on feeding sessions.

As long as it’s the right kind for the coral life in your tank, rest assured that you won’t regret the purchase.

4. Nutrient sources

Just like you, your reef cares about what it is about to eat.

In the wild corals get their nutrients from all kinds of places, including seabird waste.

Be sure to choose food with the proper ingredients for the type of corals you are caring for:

In a natural environment, corals eat an array of different types of bacteria, plankton, even small animals. The problem in a fish tank comes with replicating the massive variety that the ocean offers is quite difficult. Without all, that choice available one needs to be careful about what sources of nutrition they add to the reef tank as certain corals simply can’t take great advantage of certain foods. Amino acids, simple food particles, and phytoplankton work well for SPS corals. Zooplankton and larger food sources should be left for LPS coral polyps and zoanthids.

What’s the Best LPS and SPS Coral Snack for Optimal Growth?

With the number of brands out there, all proclaiming themselves the best, it takes a bit of doing to figure out which coral food is actually good.

Corals do need an external source of nutrients for reaching optimal growth as their nutritional requirements are not 100% satisfied by photosynthesis.

I’ve had to go through these myself, and it can be quite a slog.

For the benefit of my reef tank, I’ve checked out quite a few different brands.

Have a look at the 4 best foods for corals on the market:

1. Red Sea Reef Energy – Fantastic all-around supplements for reefs


Click here to see the current price + more photos on Amazon.

This one is probably the simplest to use on the list, which I like.

The concept here is to help boost the naturally occurring micro-fauna that already covers your coral.

This is done without adding a lot of additional organic material to the reef aquarium with the supplements used as a two-part system.

Red Sea A, the first part, is basically a nutritional liquid cocktail which targets the coral specifically.

When I first added this into the tank I noticed polyp extension pretty much immediately in my setup, so I like to think that’s a good sign.

I didn’t have any issues with clouding, or anything like that, but I was using it fairly sparingly as this stuff seems to be extremely concentrated.

Ensure that you math out the ratio to tank size correctly, as I could see some issues in this department cropping up if being careless.

Red Sea B, the second part of the system, is more supplemental.

It adds some important vitamins and amino acids into the system that help with coral growth.

Corals can synthesize a portion of essential amino acids on their own, however, this requires lots of saved up energy on their side.

So, being very adaptive organisms, they actually prefer not to do so and extract the acids from their environment.

Simply put, Red Sea Reef Energy B aids in the recreation of the conditions that help coral thrive.

Amino acids in this form help with better coral coloration, which has been the case in my coral reef aquariums as well.

Red Sea works well in reef tanks with both LPS and SPS types, and the simplicity of the system is why I think it’s a contender for the best coral food that comes in liquid form.

Just be sure not to overdo things, as this stuff is very dense.

Just a bit will do you.

Here’s an illustration of a healthy mixed reef tank where to corals were fed with the Red Sea Reef Energy A & B supplements:

By JCas06

 Advantages: 
  • Simple and straightforward
  • Targets specific mechanisms in the coral to improve growth
  • Improves coral coloration
  • Fantastic for a mixed reef with LPS and SPS corals
  • Corals don’t waste metabolic energy to break down the amino-acids (further boosting growth rates)
 Disadvantages: 
  • Can easily cause issues if overused (just follow the instructions and you’ll be fine, in my experience)
  • By targeting all coral types, it loses some of the specific strength of narrower brands (meaning – buy this if you have a mixed reef tank)

2. Reef-Roids – Very popular with many proven SPS success stories


Click here to see the current price + more photos on Amazon.

I can’t review the best food for corals without at least taking a look at Reef-Roids.

It’s widely known in reef circles as one of the greatest for pure growth purposes, and honestly, I’d have to agree.

I was fairly excited to try out this product when I initially had the chance to do so because of the surplus of positive reviews.

The formulation was originally meant for Goniopora corals, which are notoriously hard to keep alive for extended periods of time.

However, most SPS coral species and a lot of invertebrates seem to eat the stuff up.

My initial trial with Reef-Roids was targeted feeding.

I avoided aiming the mixture directly at my coral, but just sort of in front of it, letting the flow from the powerhead doing the rest.

Polyp extension was near-immediate and even the fish in the tank seemed excited by the stuff.

This was to be expected, as I had watched some videos of it in action.

I’ve actually been using Reef-Roids for a few months now, as I really just like how excited everyone in the tank gets when I add some.

What can’t be overstated here, though, is the growth rate my corals have been undergoing, month after month.

The food size ranges from 150-200 microns.

If the recommended food size for your reef falls in-between that, there’s not much that can best this food.

There’s definitely something to Reef-Roids.

I recommend getting this if you have an SPS-dominant reef tank and are okay with target feeding.

Pre-mix it with water and spot feed, using a pipette for the best results.

The next tank that’ I’m going to show has won the Reef of the Month award in the Nano-Reef.com monthly display contest.

And here’s the 29-gallon saltwater aquarium dominated by SPS corals, that have been cultivated with the Reef-Roids coral food:

By Eddy Putra

 Advantages: 
  • SPS corals love it
  • Proven growth results by many users
  • Not too expensive and you get tons in one package
  • The powder dissolves easily in the water, improving consumption efficiency
  • Coral color will also improve and get more pronounced
 Disadvantages: 
  • Its strength can be an issue if not used with care (simply follow the recommended dosage!)

3. Coral Frenzy “The Ultimate Coral Food” – Grows Fat LPS corals


Click here to see the current price + more photos on Amazon.

A friend recommended this and I ended up trying it out because I was looking for a better solution for my LPS corals.

I was also interested in testing out some pellet food varieties for my reef tank’s corals.

Coral Frenzy is pretty interesting, it’s obviously not great for filter feeders, but it was pretty cool seeing my LPS corals eat this stuff up.

The pellets themselves work great as a targeted food, be cautious not to add too much in as any excess will just sit on the bottom of the tank.

The pellets aren’t too big, but they definitely are not going to easily dissolve into your reef tank’s water column.

Of the ones I tried, Coral Frenzy definitely sits at the top of the list for the best pellet coral foods out there.

Mostly because they’re full of legitimately good ingredients, and isn’t just crude protein flakes masquerading as something special.

It takes some getting used to if you’ve mostly used powders and liquids in the past, but pellets have their uses for LPS corals and Coral Frenzy is definitely a solid choice.

My large polyp stony corals almost completely deform when they sense the food being sprinkled on them.

It is honestly one of the best LPS coral response I’ve ever witnessed.

I could almost hear the slurp…

One thing to mention is that you don’t need to follow the recommended dosage here.

Use less than what’s advertised.

This was an advice from a friend which I follow and I can’t complain.

The reef gets good growth without spoiling the water parameters.

Get the Coral Frenzy pellets if you’d like to cultivate bulky, beautifully colored colonies of large polyp stony corals in your aquarium.

Here’s a photo progression of an LPS Scoly coral responding fantastically to the Coral Frenzy food:

By CherryCorals.com

 Advantages: 
  • Easy to aim directly at coral polyps
  • LPS seem to thrive with this
  • Quality ingredients with a rich variety
  • Won’t dissolve in the water column, making it easy for the LPS to gobble it up
  • Excellent value and quantity for the money (in fact, you should even use less than the recommended dose for the best results)
 Disadvantages: 
  • Sinks quickly, can be an issue if too much collects at the bottom (avoid this by gentle target feeding)

4. Benereef – Ideal for reef owners concerned with water quality


Click here to see the current price + more photos on Amazon.

This is one of the lesser-known varieties on our list here, which was once again recommended by a friend.

That doesn’t mean, however, it should be ignored because the results we both had were quite impressive.

Benereef is best used as a multi-target coral food in reef aquariums that have multiple coral types and filter-feeding organisms.

The goal with Benereef is to target the entire tank.

Which means it’s formulated for SPS and LPS coral as well as other invertebrates and fish.

When I tried this out I had immediate polyp extension from my SPS and my fish and shrimp seemed to really love it as well.

Another thing that I noticed, and also see others reporting, is that it’s hard to pollute the aquarium with harmful inorganics with this food.

Phosphate build-up can be a problem with a reef tank, however, with Benereef it does not seem to happen at all.

This is more than welcome when you don’t really want to double up on the feeding time because you need to remove the phosphate after each session.

The food size range is definitely the widest of any we’ve looked at ranging from 3 to 3000 microns.

It’s definitely an excellent choice for anyone trying to feed all their reef tank’s inhabitants in one broad stroke.

Get Benereef if you have a mixed reef that has a history of phosphate buildup events.

And here’s a 1-year growth in a reef aquarium with many SPS corals that were fed with Benereef a couple of times a week:

Note that the user have also been feeding with the Acro Power coral food during this time.

This was done to maximize the growth potential of the SPS Acropora species.

 Advantages: 
  • Huge array of food sizes, best suiting a diversified mixed reef
  • All-in-one solution for coral and certain fish
  • You don’t need to perform water changes after a feeding session
  • Feeding requires less involvement overall
 Disadvantages: 
  • Jack-of-all-trades, but master of none

How Should You Feed Them for Maximum Efficiency?

Properly feeding your corals can seem kind of confusing at first if you don’t know exactly what you’re doing.

Sometimes a coral won’t respond immediately to a new food source.

To ensure you’re doing everything you can do to properly feed corals you should:

  1. Select an ideal feeding techniques in relation to the food used.
  2. Briefly turn off the aquarium filter and protein skimmer if target feeding.
  3. Dose with caution to avoid overfeeding.
  4. Feed after the daily photoperiod of lighting is over.

Each coral species is different, with some requiring extra care.

The first thing you should do is research deeply into your chosen coral variety to ensure they will respond properly to their food.

A major tip for when target feeding any corals, with a syringe or something similar, is to temporarily turn off your filter to limit nutrients being wasted.

Generally, you wouldn’t do this for longer than an hour, just long enough to ensure your coral has an opportunity to feed.

You could leave the powerheads on, and if you go that road, know that a moderate to gentle flow would be optimal.

Also, the trap of overfeeding is common and can have some negative effects on coral responsiveness and overall tank health fairly quickly.

Use a pipette and follow the instructions on your product of choice (unless mentioned otherwise by experienced users, like in the case with Coral Frenzy).

A good choice of coral feeder tube for target feeding that does not include sticking your hands in the tank would be the Coral Feeder SPS HPS.

What Should you get for an SPS-Dominant Reef Tank?

Even after knowing more about the varieties of food available out there, it can be difficult to choose the right one for yourself.

So first, let’s take a look at the best food recommended for SPS corals:

To put it plainly, Reef-Roids is an awesome go-to. It’s ideal for either broadcast or targeted feeding while also providing some serious robust growth. I’ve been using it a lot, as intended food for my SPS corals and they’ve really responded. I hesitate to say it’s the best on the market, but I’ll say that the reviews don’t lie about its quality.

What Should you get for an LPS-Dominant Reef Tank?

LPS corals can be seemingly insatiable in their hunger sometimes.

Since they are such big eaters, it’s important to choose something that will actually satisfy them.

Here’s what food to feed to your LPS corals:

For LPS coral food you want something that provides a lot of different nutrients and there are a few products out there that provide it in spades. For targeted feeding, check out the Coral Frenzy pellets. They pack a lot of punch and your LPS coral will thank you for it. Ingredients-wise, they really are among the best. Adding something like the Red Sea Reef Energy Supplements can help as well, as they create a balanced nutritional environment for your LPS to thrive in.

Here’s a photo of a reef aquarium that’s heavy on LPS corals to help your imagination:

Don’t Forget to Test Your Water for Overnutrification

Additional nutrients in the water can lead to disastrous consequences fairly quickly if you aren’t careful.

Bacterial and Algal blooms can crop up due to an excess of nitrates and don’t forget that nitrate producing bacteria like a lot of the same foods as a coral.

If you notice extended bouts of dense cloudiness or green cropping up, hold back on your feeding and test the water.

There’s a good chance there’s plenty of food in the water already.

What else do you need for optimal growth?

Obviously, to maximize the growth potential of your corals you’d want to ensure they are getting everything they need.

Maintaining pristine water quality is always helpful, however, the most beneficial factor aside from mechanical nutrition is proper levels of photosynthesis.

The algae organisms that form part of your corals through a symbiotic relationship are called zooxanthellae.

They photosynthesize energy from light and convert it into beneficial substances that help corals grow and survive.

Knowing the right light spectrum that triggers that response will have a tremendous impact on your reef husbandry.

You’ll also need to nail the right kind of light source in relation to water penetration and the depth of your saltwater aquarium.

Simply put, you’ll need to get your hands on the best aquarium lights for your corals. This way they can develop healthy, colorful and growing. The link leads to my guide on that and you can visit it if you’re in the middle of your research for a new reef tank.

Final Thoughts

In my experience, so far, research goes a long way in caring for corals.

Making sure you understand how these animals operate, be it LPS or SPS, helps a ton in figuring out how to care for them properly.

It can be frustrating at first, but it’s very rewarding to watch these beautiful creatures grow once the proper conditions are met.

Feeding your coral properly, and trying to give them only the best foods, is a great step in the direction of a thriving reef tank.
