Need help identifying coral?

[ejl2529]

I recently purchased a rock with zoas on it. I noticed this orange/red looking small disk on it, but I didn’t pay much attention to it. It’s now opens much bigger during the day. I was wondering if anyone could help me identify it specifically? I would guess it is some kind of mushroom... thanks for any help.

Looks like a red mushroom to me

Looks like a simple red mushroom coral they can get a little out of control so make sure to keep an eye on it if you decide to keep it.
