Aiptasia or Zoas?

[DjPhato]

Hi all, could you please help me identifying these invertebrates?
Picture 1: I spotted them on one of my recently received live rocks and tank just started cycling so they might be not so happy and would not open much.
Picture 2: I also spotted another one on a different rock that unfortunately retracted and it really looked similar to aiptasia. I was not able to take a picture before retracting. What do you think? Thanks!

First looks like zoas or palythoas. Second is hard to say

Agree on Shane’s assessment.

Thank guys…the unidentified is still closed and not extended, as soon as I can I will take a better picture

Ok i was finally able to take few more pics. It closes very quickly, not sure if aiptasia behaves like that, I never had before. What do you think? Thanks

I’m hesitant to say Aiptasia because of the textured stalk. Though it does appear you have some sort of coral in front of it too. I’m honestly not sure
