Sun Coral Qusestion

About 3 weeks ago I bought a frag of Sun Coral from Aquacon.com, The frag was in very poor condition but it opened and ate with no problem. It actually opens quite regularly, 2-3 times daily. About a week after it was in I noticed it was growing rapidly and the outside edges that where white where overgrown with yellow and now it is orange with new buds popping out. Two new heads that I can see. Is that normal? Growing that fast? Also last week I noticed a little orange speck appear on a base rock on the opposite side of the tank and it seems to be growing. It is the same color orange as the coral. Any ideas?

I will try to post a pic or two.

Yes they can grow relatively quickly when feed routinely, and start producing buds that may drop off.

 

Heres some pics, couldnt get the little growth on the base rock....camera wouldnt adjust.

 

Awesome! I've been trying to track down some myself.
