Black bugs on Zoas?

[Salted Tank]

These things are very tiny and all over my Zoas.

Nothing that I can immediately think of. #reefsquad any thoughts?

Also, there are like VERY tiny little feather duster/aptasia looking things at the bottom base. The brown and white stuff. Any idea on that? I'm tempted to just throw this plug out.

Edit: added picture

Update: After a couple of dips, the Zoa is starting to open again. Don't know the cause but at least I'm getting a positive response. Thanks all.
