Can someone ID this for me?

I found it in my live rock crevice and it is very small. Just want to make sure it's not dangerous. If you can't see it then I can try taking a better picture with a better camera.

Anyone??

Can you touch it? Is it soft like a polyp or hard like a coral skeleton?

It looks like the remains of or a closed Hidden Cup Coral.

Cup coral maybe. Here's one on a sponge that I have.

It looks like a dead coral skeleton to me.

My fingers are too big for the small hole... Let me try to find a poking device

It is definitely hard

Is yours hard like a rock?

Yes the base is hard. It has tentacles that come out sometimes.
