Help identifying if this is aiptasia!

[Avrbuster]

Could anyone tell me if this is aiptasia? I think it is, but it kind of looks pretty. It's really small so the picture is pretty poor.

We have had this tank up and running for over 6 monthes and I have never seen it before. We have not added any rocks or coral so I'm unsure how it got in there.

We had a peppermint shrimp in the tank, but I haven’t seen him in a while (not that we saw him frequently before) and we have re-aquascaped so he may have gotten trapped or worse . He may have been eating it and that's why we never saw it!?!?!?
