Bubble Coral
From Microcosm Aquarium Explorer
Overview
Related to the small bubble coral Physogyra. Colors range from white to green, blue, or tan. Characterized by the presence of large (up to 0.75 in. [2 cm] in diameter) vesicles or bubbles that arise from the polyps. Bubbles are zooxanthellae “accommodators” that, by inflation, expose their internal zooxanthellae to much more light.
Sexy Shrimp, Thor amboinensis, may adopt a Bubble Coral colony as its commensal host.
