Spikey balloon worm on my gsp frag

[eaquintero]

Got home to my gsp frag with all the polyps closes so I inspected and found these. Should I be worried? What are they?

Looks to me like a baby blue dot sea hare

I wonder how I could've gotten that in my system. It was digging in to the mat of the gsp

After looking up pictures i'm not entirely sure it is a sea hare. Any other thoughts on it?

It didn't move , but it might have died when I pulled it off from the coral

Cool, it was a lucky find, I would've never found it if I wasn't checking that frag plug. Must of came on it since since I didn't use live rock in my system
