Have these things on one of my rocks.
Anyone ID them?

look like corals closed up maybe zoas

Closed up zoanthids look like that but at some point they should open and look like zoas.

Another possibility is that they're tunicates. That's the most likely ID.

In either case they're not bad for your tank.

Tunicates

tunicates nice looking and they are not bad for the tank

Tunicates are cool, but Im pretty sure those are Zoas!! Give it a few days, they'll open up & hopefully you'll get a nice color!!

Looks kind of like Zoa's to me too. In the first pic you can see a very little bit of blue on one of them. Put them facing up towards the light and they should open up.

Good luck and keep us posted.
