Green Bubble Coral

Bubble Coral (Plerogyra sinuosa) – Care Guide & Description

Description:

The Bubble Coral is a stunning and unique LPS (Large Polyp Stony) coral, known for its large, soft, bubble-like vesicles that expand during the day. These "bubbles" range in color from pearly white to green or pinkish hues, and give the coral a soft, inflated appearance that adds elegant texture and movement to reef aquariums.

At night, the bubbles retract, revealing long feeding tentacles used to capture food. This coral is a showpiece and can thrive in a variety of tank setups with the right care.

🛠 General Care:

• Lighting: Low to moderate. Bubble Corals prefer subdued lighting, making them perfect for lower sections of the tank or shaded areas.

• Flow: Low to moderate. Gentle, indirect flow is ideal—strong flow may damage the delicate bubbles.

• Placement: Lower regions of the tank, away from aggressive corals. Ensure there’s space for the bubbles to expand without contact.

• Water Parameters:

  • Temperature: 76–80°F (24–27°C)

  • Salinity: 1.024–1.026 SG

  • pH: 8.1–8.4

  • Alkalinity: 8–12 dKH

  • Calcium: 400–450 ppm

  • Magnesium: 1250–1350 ppm

• Feeding: While photosynthetic, Bubble Corals benefit from occasional feedings of meaty foods like mysis or brine shrimp. Target feeding in the evening, when tentacles are extended, is most effective.

⚠️ Notes:

• Bubble Corals have long, sweeper tentacles that can sting nearby corals. Leave several inches of space between them and other species.

• Avoid direct handling or pressure on the bubbles, as they can be easily damaged.

✅ Ideal For:

• Intermediate reef keepers

• Low-light or shaded areas in the tank

• LPS or mixed reef tanks

• Hobbyists seeking unique, eye-catching coral with motion and texture
