Is that a sea squirt?

Next to the acro I was wondering if that was a sea squirt?

Looks like a sponge to me.

+1 for sponge, squirts that I have and have seen are not that shape or that flat, but my sponge is.

above is one of my squirts

Thanks I figured it was one of the two. I never seen it before then I moved the rock to a big tank and there it was. I love that, a early Christmas present lol
