Can someone help Id

So I bought a Zoa colony and noticed I have a few of these (like 3) that I can see, are they leathers? Right now I have them at the bottom of the tank but wondering what the needs are and it I should move it out of the sand?

If you look at the pic it’s between the zoas and the Xenia

Looks like a mushroom.
Not much required, light and water. LOL.
