Am I doomed?

[dreefer5]

7-month old mixed reef tank. I inspect my tank daily and noticed 3-4 of these only on this zoa frag that I added to the tank roughly 4 months ago. The frag has a large number of large pores and I'm concerned I may have adopted a frag with some unfriendly hitchhikers. I suspect more likely it came in on an addition of hermit crabs and snails I received 2 months ago.

Any ID help is appreciated! Is this aiptasia? The stalks are more bulbous and translucent than all of the aiptasia images I see online, although it's difficult to appreciate the translucence and shape from the video. Happy to take more pics if needed. Pardon the water particulates--this was shortly after a feeding.

Thank you!!

Yes, it is aiptasia. You'll want to inject it with lemon juice or kalk paste to kill it.

Definitely looks like aiptasia from here.

I use a syringe with .4ml of white distilled vinegar. Works great if you inject in the center.

Thanks everyone for the confirmation and advice! I had ordered some Joe's Juice just in case, but I'd prefer to avoid products without an ingredient list, so I'll give the vinegar or lemon juice a go.

White vinegar... literally 1000 and 1 uses...

I only just discovered I could toss some into my clothes washer to cut odors. It's god-tier liquid.
