Help ID, Aiptasia on zoa frag?

[JPG Corals]

Hello, new to saltwater. From what I gathered, I believe this to be aiptasia. I tried to reach for it with tongs and it retracts. Can anyone confirm what this is?

It's hard to tell under the blue lighting (white light, ex. with a flashlight, with help with identification), but the organism does look like Aiptasia.

Highlighted is what I am referring to. I did do a red sea dip X when I got these, but it seems that does not work for aiptasia.

I agree that it does appear to be Aiptasia. IME, there are multiple ways to deal with Aiptasia in Zoa colonies including Berghia nudibranchs and F-Aiptasia. The F-Aiptasia may kill a Zoa head that it covers, but IME the colony will fill back in.
