Strange coral?

I bought this live rock about a week ago. It was a new batch only in for a day before I snagged it. I really like it because it has 7 bi-valves on it and lots of other interesting things. When I got it home it had one small red spot that I was hoping was a type of coral. However I'm a little concerned at how rapidly it's growing and spreading and am a little concerned that it might be an aggressive type. It looks like a red pipe coral, much smaller version at this stage. WhenI started with the rock there was only one spot, now there's 15 and they're growing rather fast for coral. Specialy considering my lights are old and need replaced. At feeding time I can watch the pipe thingys open and close like it's feeding. Not sure if that's an issue or not?
Attaching a picture, I have several of them, this one's the easiest to see.
The top middle is one that's about 4 days old on top of a bi-valve. Directly under that is the original piece with two mouths/pipes it's under the by-valve and shadded so hard ot see. Next to it is another piece that has about 7 mouths and is about 3 days old.
Change of plans, not letting me post photo so adding link to a site with photo's
Second photo shows 10 smaller single pipes
