Common name: Bubble Coral

General Information

The Bubble Coral, scientifically known as Plerogyra sinuosa, is a captivating addition to reef aquariums, known for its distinctive bubble-like vesicles that can expand and contract, giving it a unique and appealing appearance. Native to the Indo-Pacific region, this coral is often found in sheltered reef environments where it can thrive in moderate light and water flow conditions.

Bubble Corals are popular among hobbyists not only for their beauty but also for their relatively undemanding nature compared to other coral species. They contribute to the biodiversity of reef tanks and provide an interesting texture and movement that can enhance the visual appeal of an aquarium.

Care

Caring for Bubble Coral is considered moderate, making it suitable for aquarists with some experience in coral husbandry. They prefer stable water parameters and should be placed in a location where they can receive moderate lighting and water flow. Too much flow can prevent the bubbles from fully expanding, while too little can lead to sediment accumulation.

When placing Bubble Coral in the tank, ensure it has enough space to expand its vesicles without coming into contact with other corals, as it can have long sweeper tentacles that may sting neighboring species.

Diet and Feeding

Bubble Corals are photosynthetic but can benefit from supplemental feeding. They capture plankton and small food particles from the water column, so occasional target feeding with meaty foods like mysis shrimp or brine shrimp can promote growth and health.

Behavior and Compatibility

Bubble Corals are generally peaceful but possess sweeper tentacles that can extend several inches to sting nearby corals. It's important to maintain adequate spacing between them and other corals to prevent aggressive encounters.

They can coexist with a variety of reef-safe fish and invertebrates, provided their space requirements are respected. Avoid placing them near aggressive corals that could provoke a defensive response.

Health and Common Issues

Bubble Corals can live for many years in captivity with proper care. It's crucial to maintain stable water conditions and monitor for signs of stress, such as tissue recession or failure to expand fully. Regular water changes and ensuring proper calcium and alkalinity levels can prevent these issues.

When selecting a Bubble Coral, look for specimens with fully inflated vesicles and no signs of tissue damage. Avoid corals with exposed skeletons or discolored tissue, as these can be indicators of poor health.

Habitat

In the wild, Plerogyra sinuosa is found in the sheltered areas of coral reefs, typically at depths of 3 to 35 meters. They thrive in environments with moderate light and gentle water movement, which should be replicated in the home aquarium to ensure their well-being.
