Any help in identifying this guy will be greatly appreciated. It came on a live rock I bought. Only a few days after adding it to the tank, I've noticed my toad stool not coming out at all anymore. So I'm guessing this guy stings. I've never her seen anything that looks like it before. Its soft, branchy, brown with white speckles and stripes. The ends of each branch is furry looking with lots of prickly things. Research isn't bringing anything up so thanks for any input.
