Coral ID please

The guy at the LFS threw this piece of what I think is coral into the bag with the electric blue leg hermit we bought. I've looked through liveaquaria but I can't figure out what exactly it is.

I have a coral that looks similar but its a bright green. Its called a cactus coral.

Thanks for the ID guys. Can't complain about free coral.
