Zoa Spider?

So I have a Fiery Grape colony that has gone from 100% open and thriving to 100% closed. I initially dipped, as I always do, with coral revive. After noticing the closure, I did 2 more dips over about a months time frame, with. O luck. I did a fresh water dip today to see if that would do it and this guy came out

I 21st sure if this was just a star of some sort, but the red in the middle made me question this. Amy help is appreciated.

Looks like a mini brittle star to me. With gunk on it

Yup, I agree.
