Strange growths/attachments on my Zoa's?

[astral.astrea]

So I have a frag of Nirvana zoas that I bought off of a local reefer over a month ago and I'm just now noticing these weird growths on them when they close up at night. I've also noticed weird black dots on the back of them,

Is this a sign of zoa pox? I'm a bit paranoid since I've seen them...

Could you get some pics of them under white lighting?

I think I may have found out what is growing on them: blue clove polyps.
