OK so I made that up, but check out this orange sponge that is lined with zoanthids. Its cool the way the way the orange sponge grows like a tree and the zoas form in a line, but never cross. It looks just like candy, and is so artful it doesn't even look real. To be honest I'm not even 100% sure they are zoas, but they sure look just like them.
When I first got it
I'll have to get a pick when they aren't out. Its really cool!
