Here is another picture for you experts to ID for me

This is the only one I can see this formed and could get a picture of but there are several other "orange spots" forming in the tank that don't have the black spots in them and are about half the size.

Wow...I never get anything cool like that on my live rock...

Thanks Bang Guy that gave me a place to start a search and it is what is known as a Button Tunicate.

Tunicates are awesome filter feeders, but they need so much "filth" to keep them alive that they don't last long in a fish tank.

That is what I found as odd they were not on the rock until after the rock was in the tank for almost 2 months. The water per every test I have run has been 0-0-0 for the last 6 weeks.
Then in the last week these guys show up....

Update if anyone is still following...it closed up for 2 days and I thought it was dying.
Today it opened back up and has doubled

Sorry for the crappy picture.

They're very hard to keep alive, and will close and open.
Very cool
