This sponge looking thing has been growing in a dark area under live rock. It seems to have a hole through it. Any idea?

Thanks

Good chance it is sponge.

The picture isn't that clear, but its most likely a sponge. Do you have a better pic?

Looks like sponge to me. A better/bigger pic would help.
