Spaghetti worm in GSP frag?

[MuchNameWow]

Hi guys

I'm new in the hobby and got my first frag 2 days ago. I tried cutting away a bad part today and when the lights went out I noticed tentacles comming out of the part where I cut the GSP frag. After some research I think it is a spaghetti worm. Can anyone help me identify it? I dipped the coral before putting it in the tank.

It could also be a brittle star. Hard to tell with my old eyes
