Need help identifying this thing I’m creeped out !!!

[IUSTINIAN75]

So yesterday I picked up a bubble tip anemone that came with a piece of live rock and several zoas After feeding this morning I was sitting enjoying the view and noticed a few hairy or I should say skinny long tentacles emerging from holes in the rock and one of them even was stealing food that I gave the anenome by reaching right in! What is this!?!?

 

[IUSTINIAN75]

I had tentacles coming out of multiple holes at once I tried using a light to see into the rock maybe catch a peak but it seams that the tentacles are v long!

Perhaps a brittle starfish

 

[JNalley]

yeah, I'd say brittle or serpent star, I say serpent because of the ringed stripes, all my brittles have been black, while serpents have those ringed stripes

 

[Sharkbait19]

There is a type of peanut worm that has black and white stripes like that.
Though by the “hairy” description I’m inclined to say brittle star.

 

[JNalley]

Heh, I just tried to search for a serpent starfish, and it seems that the ones with smoother arms are called serpent and the ones with hairier arms are called brittle but that they're all the same family. If that's what it is, it's good CUC

 

[IUSTINIAN75]

So from the searches I made I believe it to be a brittle starfish stay tuned if he comes out I will post updates and pictures

Perhaps a brittle starfish

So here are some updated shots I was able to get after moving the rock a bit

They naturally live in crevices

They naturally live in crevices

Yeah -- not stuck. They're unbelievably flexible.
I usually only ever see a few arms of mine sticking out.

...but, just for fun, here's a pic of a couple when they were out:
