hitch hiker ID?

I got 3 coral frags today from the LFS. There was something on the rock with my finger leather. Can anyone tell me what it is? (praying it's not aiptasia) It doesn't have a stalk, and the tentacles have horizontal stripes on them. Thanks in advance!

Ok so I took a syringe and shot boiling water at it, but then I remembered I have 5 peppermint shrimp! One came up and took a chunk out of it! So I think it's as good as gone!
