Pearl Bubble Hard Coral (Plerogyra sp.)

(Also known as Bubble Coral, Grape Coral, or Pearl Coral)

Overview

The Pearl Bubble Hard Coral (Plerogyra sp.) is a beautiful and distinctive large-polyp stony (LPS) coral, prized for its translucent, pearl-like vesicles that resemble clusters of bubbles or grapes. These bubble-like polyps gently expand and contract throughout the day, giving the coral a soft, fluid appearance. Available in shades of white, green, silver, and cream, the Pearl Bubble Coral adds both texture and elegance to reef aquariums. Hardy, slow-growing, and captivating, it is best suited as a feature coral in low to moderate flow environments.

Origin

Native to the Indo-Pacific region, including the Coral Sea, Great Barrier Reef, Fiji, Tonga, Indonesia, and the Red Sea. Commonly found in shallow, sheltered reef slopes and lagoons, where light is moderate and water movement gentle.

Feeding

The Pearl Bubble Coral is photosynthetic, deriving most of its nutrition from zooxanthellae within its tissues. It also benefits from supplemental feedings that encourage growth and polyp expansion. Feed 1–2 times per week with:

  • Mysis or brine shrimp
  • Finely chopped seafood
  • Marine plankton or LPS coral foods

Target feeding at night or when tentacles are extended will yield the best results.

Lighting

Low to moderate lighting. The bubble-like vesicles are sensitive to intense illumination. Provide diffused light from LED, T5, or hybrid systems.

  • PAR range: 75–150 ¬µmol/m¬≤/s
  • Avoid direct, high-intensity light that can cause bleaching or tissue retraction.
  • Under blue-spectrum lighting, the vesicles exhibit a pearlescent, fluorescent glow.
Water Flow

Low to moderate, indirect flow. Gentle, variable currents are ideal to keep the coral’s bubbles gently swaying while preventing debris from settling. Avoid strong or direct jets of flow, which can tear delicate tissue or cause the vesicles to deflate.

Placement
  • Position on the substrate or lower rockwork in a sheltered area with indirect light and flow.
  • Provide at least 15 cm (6 inches) of space from other corals to prevent stinging contact.
  • Avoid sharp rock edges — the delicate bubbles can rupture easily.
  • When fully expanded, colonies can double or triple in apparent size.
Tank Mates

Reef safe with caution. Compatible with:

  • Peaceful reef-safe fish (gobies, blennies, clownfish, tangs, etc.)
  • Snails, shrimp, and small hermit crabs
  • Other non-aggressive LPS or soft corals with sufficient spacing

Avoid:

  • Aggressive corals (e.g., Euphyllia, Galaxea, Hydnophora)
  • Large angelfish, butterflyfish, or puffers that may nip at the polyps
  • Crabs or shrimp that may climb and irritate the bubbles
Aggression

Moderately aggressive.Plerogyra corals extend long, stinging sweeper tentacles at night to defend their territory. Maintain clear spacing from nearby colonies and ensure steady water movement to disperse toxins.

Experience Level

Intermediate. The Pearl Bubble Coral is hardy once established but sensitive to excessive light or flow. Stable water parameters and careful placement are key to long-term success.

Water Parameters
  • Temperature: 24–27°C (75–81°F)
  • pH: 8.1–8.4
  • Salinity: 1.024–1.026 SG
  • Alkalinity: 8–12 dKH
  • Calcium: 400–450 ppm
  • Magnesium: 1250–1350 ppm
  • Nitrate: <10 ppm
  • Phosphate: <0.03 ppm
  • Tank Size: Minimum 100 litres (25 gallons) for a single colony; larger systems preferred for stability
Reef Compatibility

Reef safe with caution. The Pearl Bubble Coral adds dramatic form and movement to mixed reef aquariums, but requires adequate space and gentle flow. Its large, soft vesicles are highly photosensitive and can be damaged by rough handling or high flow, so it’s best displayed in a protected, open area where it can fully expand.




Interesting Fact

Each “bubble” on Plerogyra corals functions as a light-modulating structure — expanding during the day to maximise photosynthesis and deflating slightly at night when feeding tentacles extend to capture plankton from the water column.

Strong and Durable, Great for Large Garbage Cans
Scent: Unscented, Size: 50 Count (Pack of 1)
I’ve got a large garbage can for a big family, and in the past, every other brand of bag I tried would always slip down when filling it, turning trash day into a messy nightmare. I finally decided to look for a heavy-duty, extra-large bag and found these 30-gallon Glad bags—and I’m glad I did. I even tested three different brands to see which one I liked best, and these came out on top by far. They’re rip-resistant, strong, and extra roomy, making them perfect for a busy household. Even if they’re a little more expensive than other bags, the durability and reliability make them totally worth the extra cost. No more wrestling with sagging trash bags!

Been Using These for Years
Scent: Unscented, Size: 50 Count (Pack of 1)
I have been using these Glad 30 gallon ForceFlex trash bags for years and they never disappoint. The black color looks clean, they are thick and strong, and the unscented option is perfect if you do not want artificial smells. They hold up well with heavy trash, resist leaks, and the drawstrings make them easy to tie and carry. Great quality and worth the price.

Holds up really well in my house!
Scent: Unscented, Size: 50 Count (Pack of 1)
Good trash bags. They hold up really well and do not tear like most trash bags do. Would recommend. Do not notice a strong scent to them either.

still the best
Scent: Unscented, Size: 50 Count (Pack of 1)
Update from after they changed the bags to the two layer bags. I was alerted by another customer that the bags on the page changed, and she scared me away from trying the new version so much I bought the Hefty bags. Well, I am back. I did not like those, they are stiff, but they slash through easy and I did not like the smell. I looked again into glad bags, and realized that they did not get thinner. They are now two layers. Each of the two is thinner, but together they make for a stronger bag. It works just like when the cashier at the grocery store double-bags your heavy milk cartons. I used up a smaller box of this new dual defense variety and went back on amazon to buy the bigger box. They work the same as the old ones. They are strong and do not rip under normal conditions. I like how stretchy they are. The outside layer is white, inside layer is black. The bags look gray from the outside as the black shows from under the white. It looks black from the inside, and you cannot see gray when it is in the garbage can in the kitchen. Original review: Those are my favorite bags. I use them in my regular size kitchen garbage can, because it is black and I do not like how white bags show when used inside of trash cans. And I do not like to use clear bags - who wants to see the garbage? So, black it is. I like that the bags are bigger than the can since I never have any problems closing the bags and can fit a pizza box or something extra that would not fit into the can and waits for its turn behind the can. Forceflex bags are truly tough, they can stretch around items instead of tearing, and the red ribbon inside is thick and attached securely, too, so it stays where it supposed to be, and I do not get any nasty surprises on my way to the outside bin, and my trash collectors never have to pick up fallen garbage from the road, too.
