Bubble Coral – A Bold Centerpiece That Commands Attention

If you're after a showstopper that brings volume, motion, and texture to your reef setup, the Bubble Coral (Plerogyra sinuosa) delivers in a big way. This is not your average filler coral—it’s a high-impact specimen that stands out immediately in any aquascape.

The Bubble Coral gets its name from its signature oversized vesicles, or “bubbles,” which expand dramatically during the day. These inflate in shades of pearlescent white, jade green, or soft pastel blue—depending on the morph—creating a glowing, almost alien presence under blue LED lighting. At night, the bubbles recede and expose its hidden feeding tentacles, giving you a whole new look to appreciate after lights-out.

This coral typically grows in a mounding, dome-like formation, forming thick, fleshy lobes that originate from a calcified, non-branching base. Colonies expand relatively fast in stable systems, offering impressive visual mass with a minimal footprint on your rockwork. It’s hardy and forgiving, but it can get aggressive—long sweeper tentacles mean it claims its space, so give it some breathing room.

- Care Level: Moderate
- Lighting: Moderate to Low – thrives under LED, T5, or hybrid systems
- Flow: Low to Moderate – doesn’t like being blasted
- Placement: Lower to Mid in the tank, with ample surrounding space
- Growth Form: Meaty, dome-shaped, encrusting base with expanding bubble vesicles

Whether you’re curating a standout LPS zone or just want a coral that delivers impact both day and night, the Bubble Coral earns its real estate. It’s a must-have for reefers who want serious texture, motion, and visual punch—without the fragility of high-maintenance showpieces.
