Some kind of Polyps.

 

[supertech3]

they look like xenia's

 

[doox00]

xenias a good thing?

 

[supertech3]

Yes like a grass that really spreads with proper conditions

xenia are one of the fastest growing corals and they look like xenia but you would be very lucky to have xenia come in on a piece of live rock. Polyps are more likely. Xenia is cool and there is the pulsing kind as well as the non pulsing kind. Xenia grows so fast it can sometimes take over a tank. In my experience, after i gave away as much as anyone would take, I took to throwing it in the trash about every 5 weeks. It's great but you do have to prune unless you want a xenia tank.

looks like polyps to me too

 

[doox00]

what exactly are polyps btw?

 

[Amphiprion]

My guess would be Briareum.

 

[Paintbug]

the white centers and encrusting base rule that out.

they look like green star polyps as indicated by the flesh growing on the rock too and thats a very hard coral.

 

[fishgirl7]

look at the biggest polyp on the right- looks like a green star polyp-thats what mine look like!

It is the start of a hand waving pulsing Xenia.....I have the same in my Nano....it is fun coral and it will be the first to react to any bad things happening in your tank.

 

[doox00]

it is a little larger now/spread out some, I will take pictures this evening when I get home from work.. they close up when the lights are off it seems, to just a stem, and semi retract a bit.

 

[klhscooter]

it will stretch out in the light and the hands will open and close. The hands close up in darkness and the stalks shorten up. I really enjoy watching this coral and it does travel. The first piece I put in immediately started to move from the frag rock to the large live rock.

I agree with the others that these are some type of encrusting star polyp, but I'm not so sure they are the common GSP's (may be a clove polyp type).

Having xenia and anthelia also, I don't believe this to be either. The reason is because xenia, when it comes up from a plaque of forming polyps, does not start with having a long "neck", and these do. It is definitely not anthelia, which form distinct podlike polyps when they grow out. This is not the case here, where there's an encrusting element.
