Bubble Coral Care Guide
Plerogyra sinuosa · Saltwater LPS Coral
What Bubble Coral look like
Plerogyra sinuosa, commonly known as Bubble Coral, exhibits a distinctive morphology characterized by its large, inflated, bubble-like polyps that can reach up to 10 cm in diameter. The coral typically forms a branching or encrusting structure, with polyps that are often extended during the night for feeding. The coloration of the polyps can range from green to brown, with some specimens displaying vibrant hues due to zooxanthellae symbionts. The skeletal structure is composed of a series of interconnected, calcareous septa that provide support and protection. Bubble Coral exhibits minimal sexual dimorphism, as both male and female polyps share similar external characteristics. Its defensive adaptations include the presence of nematocysts within the tentacles, which can deliver a mild sting to deter potential predators. Unique to this species is its ability to retract its polyps significantly during the day, reducing exposure to intense light and potential desiccation.
Behavior & temperament
Bubble Coral is primarily a sessile organism, exhibiting a slow growth rate and limited movement. It extends its polyps during the night to capture plankton and small particulate matter, employing its stinging tentacles to immobilize prey. This species can engage in aggressive interactions with neighboring corals, utilizing its nematocysts to compete for space and resources. Plerogyra sinuosa often forms symbiotic relationships with various species of fish, which may seek refuge within its polyps. The coral's feeding behavior is opportunistic, relying on both photosynthesis from its symbiotic zooxanthellae and heterotrophic feeding. Its temperament is generally peaceful, but it can exhibit territoriality when in close proximity to other corals.
Diet & feeding
Bubble Coral is primarily a heterotrophic feeder, capturing zooplankton and organic debris from the water column. In captivity, it requires a diet supplemented with finely chopped meaty foods and can benefit from regular feedings of phytoplankton.
Behind the name
The genus name 'Plerogyra' derives from the Greek words 'plero' meaning 'full' and 'gyra' meaning 'coil', referring to the bubble-like appearance of the polyps. The species name 'sinuosa' comes from the Latin word for 'curved' or 'winding', describing the shape of the coral's structure.
