Pearl Bubble Coral Care Guide

Plerogyra sinuosa, commonly called Pearl Bubble coral is a large polyp stony (LPS) coral. Also known plainly as "Bubble corals," the term appropriately describes their retractable, circular, bubble-shaped polyps. Pearl Bubble coral polyps can be found in shades of white, blue, tan, and green. Colonies can grow to approximately 12 inches in diameter, but are usually smaller.

Pearl Bubble corals require lower lighting combined with low water flow. We recommend around 150 PAR. They prefer to be placed anywhere from the middle to the bottom of your reef as long as the lighting is not intense and the water flow isn't strong enough to damage their fragile polyps. 

Through their symbiotic relationship with a photosynthetic algae, known as zooxanthellae, Bubble Pearl corals receive many of their nutrients. They actually expand their bubbly polyps to permit more light to enter to aid this process. It is strongly recommended to provide them with additional foods like brine shrimp or krill as they require more nutrition. For continued good health, it will also require the addition of calcium, strontium, and other trace elements to the water. 

Although they are fragile, Pearl Bubble corals are aggressive and will use their long sweeper tentacles to sting corals that are too close. They also do not tolerate disturbances from other tankmates, such as hermit crabs that can easily damage them. Be sure to give them their space to grow and thrive undisturbed. Use caution when handling as they may release toxins that can irritate your hands.
