The White Bubble Coral Plerogyra sinuosa is a breathtakingly beautiful large polyps stony (LPS) coral, that can be easy to care for. Needing only gentle water movement and low to moderate light, this easy LPS coral has very few demands. Sometimes called 'Grape Coral', the P. sinuosa from Australia will actually inflate or deflate their water filled vesicles (bubbles) depending on the light available. All Bubble Corals have lightweight skeletons consisting of short thick stalks topped with corallites. This skeleton is hidden by the oval water filled vesicle bubbles. These bubbles only come out during the day light. At night they retract, making way for their tapered feeding tentacles to come out and gather prey. Be cautious, while the bubble does not have toxins, they have feeding tentacles which are capable of delivering a sting to any coral invading its space.
Difficulty It is easy to maintain in the reef aquarium, which makes it an excellent candidate for the beginning through expert reef aquarist.
Aggressiveness Be cautious, while the bubble does not have toxins, they have the feeding tentacles which are capable of delivering a sting to any coral invading its space.
Does best with gentle water movement.
Does well under lower lighting levels. They can do well under stronger lighting too as long as the bubble coral is placed under a shelf, or in a less lit corner of the tank. T5's, Metal Halides, or LED's can all grow Tongue Coral when the proper levels are provided. We recommend a 14-20K color spectrum for best coloration.
A well-feed live rock/reef environment is what is needed for Bubble Coral , along with some fish for organic matter production.
Diet and Feeding
Best to feed in the evening when the feeder tentacles are out. Feed mysis, rotifers, enriched brine shrimp, Cyclopeeze and other similar sized meaty foods. Try to not feed large pieces since it makes it difficult for the animal to digest such foods and often results in them regurgitating late at night. When this happens, they are not benefiting from the feeding and it can lead to eventual starvation.
It is best to feed them well and keep them happy, then they will form buds which can be harvested and produce quite a few colonies a year! Just be patient. The larger your coral gets, the more "babies" it will give you.
