Yip Zoe's are the same. After 3 months of darkness in the sump there was a very thin matt of Zoe's you could just see the raised bumps in the matt where the pollups are.
I put the rock back in the display and One month later the tiny raised bumps are opening , in a week or two they will have made a full recovery.
I had to sump a few rocks as they were leaching phosphates and growing GHA ,I'd rather them do that in the sump where I can't see them.
If those were star pollups I think you would be Abel to see the matt
