Elegance Coral: Catalaphyllia jardinei

Elegance coral (Catalaphyllia jardinei) is an excellent large polyp stony (LPS) coral for the mixed reef tank. This elegant coral is an anemone look-alike and has long, flowing tentacles, although it is more closely related to frogspawn, torch, and hammer corals than sea anemones. Several different color morphs/varieties are available, so if you shop around, you can find the perfect look you crave.

Let’s dive right into the guide on how to care for the Elegance coral in a saltwater aquarium!

Elegance Coral Ideal Habitat

In the wild, these majestic invertebrates can be found in the Great Barrier Reef around Australia and some areas near Japan, Vanuatu, Micronesia, and Mozambique. They stay in the shallower and mid-range parts of the reef, not straying much further than 130 feet (40m). You almost always spot them in sandy parts of lagoons and seagrass beds.

This natural habitat is key to understanding their needs in the aquarium. Elegance corals are adapted to rest on soft, sandy substrates in areas with gentle water movement and minimal sharp or abrasive surfaces. Their fleshy base and large polyps expand outward and downward, making them poorly suited to rocky or jagged surfaces, which can cause tissue abrasion, instability, and increase the risk of infection or recession. In the home aquarium, placing Elegance corals directly on the sandbed, ideally in a shallow depression or “nest” created in the sand, helps mimic their natural environment and minimizes the risk of tissue damage. Avoid wedging them into rock crevices or placing them on unstable or rough surfaces, as this can lead to chronic stress or injury.

Because this coral will grow to a relatively large size if healthy, Catalaphyllia jardinei is best suited to larger tanks. A 90-gallon saltwater tank would be perfect and allow plenty of room. However, that’s under the assumption that you would like to keep this coral along with several other species. If you wish to support this coral in a smaller tank, consider making it the focal point and provide plenty of room to grow.

You’ll need to make sure you observe basic reef water parameters. For example, elegance corals do well with your standard aquarium salt mixes.

Placement of Elegance Corals in a Reef Tank

Elegance corals generally thrive when placed within the bottom to the middle of the tank, depending on the relative intensity of your lights and the depth of your tank. They also need to be placed a significant distance from neighboring corals.

The bottom of the tank is generally an area of moderate-to-lower lighting and moderate-to-lower flow, which is ideal for this species.

Always acclimate any coral, including these LPS, gradually when introducing them to new lights.

Lighting

Elegance corals require a moderately high amount of light to support photosynthesis, but that doesn’t translate to intense light. LEDs, fluorescent, or other reef-caliber lights will be sufficient. You want to aim for a PAR of about 80-120. PAR stands for Photosynthetically Available Radiation, which is how you measure the quality of the light.

Moderate lighting is important because Elegance corals rely on their symbiotic zooxanthellae for much of their nutrition, but they are sensitive to sudden changes or excessive intensity. Too much light can cause tissue retraction, bleaching, or loss of color, while too little can result in poor growth and excessive stretching (expansion) as the coral tries to capture more light. Signs of light stress include pale or bleached tissue, persistent retraction, or the coral remaining closed for extended periods. To prevent stress, acclimate new Elegance corals by starting them in lower light areas and gradually increasing PAR over several weeks. In practical terms, “moderate” lighting for most home aquariums means avoiding direct placement under high-output LEDs or metal halides, especially in shallow tanks, and instead choosing a spot with filtered or indirect light.

Flow

Water flow is vital in every reef tank containing coral. Since Elegance corals have large, fleshy polyps, the critical descriptor here is MODERATE. (Think Goldilocks and the three bears) You don’t want the flow to be too hard or too soft. “Just right” means the tentacles flow gently, like leaves in a light wind. Too little and Catalaphyllia jardinei will not thrive. Too much flow, and you risk tearing the delicate polyps.

Proper flow is essential for gas exchange, nutrient delivery, and waste removal. Moderate, indirect flow helps keep the coral clean and healthy, while excessive direct flow can cause tissue tearing, polyp retraction, or even lead to infection through repeated abrasion. Insufficient flow, on the other hand, may allow detritus to accumulate on the coral, increasing the risk of tissue recession and disease. Diagnostic cues for flow problems include tentacle collapse, persistent tissue recession, excessive mucus production, or the coral remaining closed. Adjust flow by repositioning powerheads or using indirect currents to achieve gentle, swaying movement of the tentacles—never a forceful blast.

The proper flow brings nutrients to the polyps, ensuring they remain nourished. And you’ll see the typical “sweeping” movement as they drift in the current. You’re not going for a cyclone, more of a dramatic sweep.

Feeding the Elegance Coral

The Elegance coral has photosynthetic algae, called zooxanthellae, living inside its body tissue. These algae help provide the coral with some of the nutrition they need. However, they also benefit from regular feedings.

What should you feed your elegance coral?

Your coral will greedily accept soft, meaty foods. Some notable foods are krill, Mysis shrimp, brine shrimp, or small pieces of fish, shrimp, or shellfish.

Care should be given to the size you feed this coral. Preference is given to high-quality foods that are relatively smaller in size. An Elegance coral may greedily accept larger-sized food, but it may get regurgitated later if it is too large to reach the digestive tract.

There is a trade-off between feeding frequency and water quality. More frequent feeding can promote faster growth and better polyp expansion, but it also increases the risk of nutrient spikes, algae blooms, and deteriorating water quality if uneaten food or coral regurgitation is not removed. Signs of overfeeding include regurgitated food, tissue swelling, or cloudy water. To balance nutrition and tank health, feed small portions 1-2 times per week, using foods that are easily consumed and digestible. After feeding, consider running your protein skimmer and removing any uneaten food to help maintain water quality. Monitor your nutrient levels and adjust feeding frequency as needed to avoid excess nitrate or phosphate buildup.

Behavior and Compatibility

Clownfish and other species with symbiotic relationships with anemones are excellent tank mates for Elegance corals. If you’re lucky, these animals may take a liking to your corals and settle in as a new home. Some individual colonies will tolerate this well; others may seem bothered by it.

Elegance corals are highly aggressive members of the LPS coral group. They use both physical means (long sweeper tentacles) and chemical warfare to compete for space. Sweeper tentacles can extend up to 6 inches (15.2cm) beyond the base, delivering potent stings to neighboring corals. Chemical aggression can also inhibit the growth of nearby species. As colonies grow, their reach and aggression can escalate, sometimes resulting in “surprise” stings or slow tissue recession in neighboring corals that were previously out of reach. Underestimating aggression distance can lead to tissue loss, coral death, and tank instability.

To manage territory in a mixed reef, provide ample free space—at least 6 inches (15.2cm) or more—around Elegance corals, and monitor as they grow. Good companion corals include Blastomussas, Scolys, Plate Corals, Favia, and Acans, provided sufficient spacing is maintained. Avoid placing Elegance corals near other aggressive species with potent sweepers, and keep them away from fish species known to nip at coral polyps, as Catalaphyllia jardinei may become a target.

Elegance Coral Tips and Advice

If you are thinking about adding an elegant coral to your tank, here are a few elegance coral tips:

• Look at the coral polyps carefully before purchasing. Avoid buying a specimen with polyps damaged in transit. Sometimes, these corals don’t recover from serious injuries.
• Don’t forget that corals are animals, not plants, and this coral likes to eat. So be sure to feed it regularly to get the best growth.
• Give it space to grow into. Then, even a year or two from now, make sure it will still be far enough away that it can’t sting its neighbors.

Elegance corals ARE prone to elegance coral syndrome (ECS). The infection targets Catalaphyllia species, particularly individuals gathered from Indonesia. You’ll see swelling around the oral disc and unopened polyps or a white mucus coating. Unfortunately, there isn’t a cure for ECS. This is why you want to quarantine any new purchases – AND ask where they were harvested in the first place. DON’T attempt to frag “healthy” portions, either. You could kill the coral in the process.

Suspected contributing factors for ECS include collection and shipping stress, poor water quality, and rough handling. ECS can be distinguished from other stress responses by the presence of persistent swelling, failure of the polyps to open, and the development of a white, mucous coating. To reduce risk, source Elegance corals from reputable suppliers, prioritize specimens collected from regions with lower ECS incidence, and quarantine new arrivals for an extended period to monitor for symptoms. Maintain stable tank conditions and avoid sudden changes in lighting, flow, or water chemistry.

For More Information

If you are looking for a hardy LPS coral that looks great and is relatively easy to care for, this Elegant coral (if you prefer) is a good choice. Keep lighting and water flow moderate and give it space to grow.

For long-term success, regularly monitor your Elegance coral for signs of tissue recession, polyp retraction, or overgrowth. As the coral matures, periodically reassess its placement and the proximity of tankmates to ensure continued health and prevent aggression-related issues.
