Just for the record there is no purple zooanthellae. All zooanthellae are varying shades of gold/brown, it's the coral pigment itself that gives you different colours.
Where does the coral get it's pigment from after bleaching? There is said to be 3 varieties of zoaxanthelea and each is affected by different spectrums. We are obviously reading different studies.
