Plerogyra and Physogyra (Bubble Coral)

Common names: Bubble coral

Difficulty Level:  Bubble Coral is generally tolerant, but must have stable alkalinity to survive.

Feeding: Poor feeding response, so must usually be fed with pumps off. Most common foods are small suspension matter including phyto and roti.

Lighting (Level 6 to 8): Most prefer moderate lighting, but will adapt to varying conditions.

Water flow: Lower to moderate flow is best to keep from damaging this corals large fleshy polyps.

Placement: Bubbles coral is very aggressive and should be placed where it can not sting other corals. Be sure to leave space for the polyps to expand without being brushed against rocks.

General: The big inflatable bubbles seen during the day turn in to long feeder tentacles at night. It’s thought that the bubbles expand to best capture light during the day, but are then adapted to best capture food at night.
