Bubble Coral (Ultra) SPS Both have identical care needsThis coral receives most of its energy by utilizing the photosynthetic algae contained within its tissues. At night time it will retract the bubbles and extend its feeding tentacles, and will benefit from meaty foods such as mysis shrimp, enriched brine shrimp, oyster eggs, pellets, etc. It can alter the size of its bubbles to expose its symbiotic algae to more or less light, however like all corals sudden changes in light intensity should be avoided.
