zooxanthellae question

[Psilopsyche]

Not sure if this is the right forum for this question, so please redirect me if it not. I was wondering if all coral has zooxanthellae or just the photosynthetic ones.

just the photosynthetic ones - they are photosynthetic by virtue of having Zooxanthellae algae which performs the photosynthesis.
