Do Tubastrea corals function as a full organism or does each polyp require its own food source? At my work we've been getting in large Tubastreas fairly regularly and i feed them whenever i get the chance but they sell so quickly that i've never been able to see a decline in health from polyps that usually don't get fed. Everybody i've asked so far has said the polyps function as seperate organisms but nobody's been 100% and seeing as they're all connected it would seem that the coral could share nutrients across all of its polyps. All help is appreciated.
