How to Buy Coral Online: A Complete Guide for Reef Keepers

Buying coral online has opened up a whole new world for reef keepers. Instead of being limited to what is available at your local fish store, you can now find everything from beginner-friendly zoanthids and mushrooms to colorful Euphyllia, SPS, anemones, and unique aquacultured corals from sellers across the country.

But ordering a living coral is a little different from ordering a normal product online.

Before placing an order, you should know what you're buying, how it will be shipped, what to expect when it arrives, and how to give your new coral the best chance of thriving in your reef.

At Ken's Reef Tank, we grow, keep, sell, and ship live coral, so we've put together this guide to help reef keepers understand what to look for when buying coral online.

1. Buy From a Seller Who Actually Knows Coral

A good coral seller should be able to tell you more than the name and price of a coral.

Look for a seller who can provide information about things like:

• Lighting requirements

• Flow requirements

• Coral placement

• Temperament and compatibility

• General water parameters

• Acclimation

• Coral dipping

• Growth characteristics

This becomes especially important when buying LPS and SPS corals that may have more specific requirements.

A knowledgeable seller should also be willing to answer questions if you're unsure whether a coral is appropriate for your aquarium.

2. Understand WYSIWYG vs. Representative Corals

You'll often see the term WYSIWYG when shopping for coral online.

It stands for:

What You See Is What You Get.

A WYSIWYG listing means the coral pictured is the actual coral you are purchasing.

This can be particularly helpful when purchasing corals where coloration, size, number of polyps, branching structure, or pattern varies significantly from one specimen to another.

Other listings may use a representative photo. In that situation, you're purchasing the same type or variety of coral, but the exact frag you receive may differ slightly from the coral pictured.

Neither type of listing is necessarily better. The important thing is knowing which type you're purchasing.

3. Don't Shop Based on Color Alone

We've all done it.

You see an incredible coral online and immediately start thinking about where it's going in your tank.

But before hitting the buy button, make sure the coral is actually suitable for your aquarium.

Research its requirements for:

Lighting: Does it prefer low, moderate, or high PAR?

Flow: Does it prefer gentle movement or stronger, more turbulent flow?

Space: Does it have long sweeper tentacles or another way of damaging nearby corals?

Difficulty: Is it appropriate for a newer reef tank?

Stability: Does it require very stable alkalinity and nutrients?

A beautiful coral isn't a good purchase if your aquarium can't provide the environment it needs.

4. Aquacultured Coral Can Be a Great Choice

Aquacultured coral has been grown and propagated in aquarium conditions rather than recently collected from the ocean.

This can offer several advantages for reef keepers.

Corals that have spent significant time growing in aquarium systems are already accustomed to captive conditions such as artificial lighting, prepared foods, aquarium flow, and typical reef-tank water chemistry.

Aquaculture also allows desirable coral to be propagated repeatedly through fragging rather than relying entirely on newly collected specimens.

At Ken's Reef Tank, growing and propagating coral is a major part of what we do. Our goal is to grow healthy coral that can continue growing in another reef keeper's aquarium.

5. Look at the Seller's Shipping Method

Shipping is one of the most important parts of buying coral online.

Live coral shouldn't spend several unnecessary days moving through the shipping network.

Whenever possible, look for sellers using an appropriate expedited shipping method for live coral.

At Ken's Reef Tank, we ship coral nationwide using overnight shipping.

Depending on the weather, coral shipments may also require temperature-management measures to help protect livestock during transit.

Weather matters on both ends of the shipment. The temperature where the coral is leaving can be completely different from the temperature at its destination.

6. Read the DOA Policy Before Ordering

Every online coral buyer should read the seller's Dead on Arrival (DOA) policy before purchasing.

Don't wait until there's a problem.

A DOA policy should explain:

• How quickly a problem must be reported

• What photographs or documentation are required

• Whether the coral must remain in its original bag

• How credits or replacements are handled

• Whether shipping costs are covered

Policies vary between coral vendors, so knowing the rules ahead of time prevents misunderstandings.

Ken's Reef Tank maintains a DOA policy to protect both our customers and our livestock shipments.

7. Remember That Coral Can Look Different After Shipping

Don't panic if your new coral doesn't look exactly like its website photo five minutes after opening the box.

Corals can become stressed during shipping.

A coral may arrive:

• Retracted

• Deflated

• Closed

• Producing mucus

• Showing less coloration

• Looking very different under normal room lighting

Zoanthids, for example, may remain closed initially. Euphyllia may arrive completely retracted.

Give the coral time to adjust while following appropriate acclimation procedures.

Also remember that coral coloration can look different depending on aquarium lighting, spectrum, camera settings, filters, and viewing conditions.

8. Inspect and Dip New Coral

Before placing a new coral into your display aquarium, inspect it carefully.

Look at the coral itself as well as the frag plug or rock it arrived on.

You're checking for things you don't want entering your reef, including unwanted algae and potential pests.

Many experienced reef keepers also use an appropriate coral dip as part of their introduction process.

Different corals can have different sensitivities, so always use a dip that is appropriate for the coral and follow the manufacturer's instructions.

For reef keepers with the space available, a dedicated coral quarantine or observation system provides another layer of protection.

9. Acclimate the Coral to Your Lighting

A coral coming from one aquarium may have been growing under completely different lighting than yours.

Even a coral that ultimately prefers strong light can become stressed if it's moved immediately into much higher intensity.

When you're unsure about the lighting conditions the coral came from, starting conservatively and gradually acclimating it can be safer than immediately exposing it to maximum intensity.

This is another reason it's helpful to purchase from a seller you can talk to.

Ask what type of lighting and general intensity the coral was growing under.

10. Stability Matters More Than Chasing a Perfect Number

Reef keepers love numbers.

Alkalinity, calcium, magnesium, nitrate, phosphate, pH, salinity, temperature and PAR can all be important.

But constantly changing your aquarium trying to hit somebody else's "perfect" number can create its own problems.

Corals generally benefit from a stable, appropriate environment.

Before ordering new coral, make sure your aquarium is ready for it.

If your alkalinity is swinging dramatically, salinity is unstable, or you're currently dealing with a significant aquarium problem, it may be better to correct those issues before adding more livestock.

11. Start With Coral Appropriate for Your Experience Level

You don't need to start your reefkeeping journey with the most expensive or demanding coral available.

There are plenty of beautiful corals that can be excellent choices for newer reef keepers.

Depending on the aquarium, possibilities can include:

• Zoanthids

• Mushrooms

• Certain leather corals

• Green star polyps

• Some LPS corals

As your aquarium matures and you become more comfortable managing water chemistry, lighting, flow, and nutrients, you can gradually expand into other types of coral.

12. Ask Questions Before You Buy

This might be the simplest advice in this entire guide.

Ask questions.

If you aren't sure whether a coral will work in your aquarium, contact the seller before purchasing it.

Tell them:

• Your tank size

• How long the aquarium has been running

• Your lighting

• Your flow

• Your current parameters

• What other coral or livestock you keep

A good coral seller would rather help you choose an appropriate coral than sell you something that isn't a good match for your system.

Frequently Asked Questions About Buying Coral Online

Is it safe to buy coral online?

Yes. Live coral is routinely shipped throughout the United States using appropriate packaging and expedited shipping. The seller's packing practices, shipping method, weather conditions, and livestock policies are important considerations.

Can coral survive overnight shipping?

Healthy coral can generally tolerate properly prepared overnight transportation. Coral may still appear stressed or retracted immediately after shipping and can require time to recover.

Should I dip coral purchased online?

Inspecting every new coral is recommended, and many reef keepers incorporate coral dipping into their introduction process. Make sure the product and procedure you use are appropriate for the particular coral.

What does WYSIWYG coral mean?

WYSIWYG means "What You See Is What You Get." The coral shown in the listing is the individual coral being sold rather than a representative example.

What are good corals for beginners?

Zoanthids, mushrooms, certain leather corals, green star polyps, and some LPS corals can be beginner-friendly choices depending on the aquarium. No coral is completely maintenance-free, so research the requirements of each species before purchasing.
