Can you help Identify this?

I bought a small frag of this (the size of a quarter) when I first setup my tank. Since that time, it has completely covered 1 large rock and is starting to popup on other rocks. However, no one I have shown a picture to can tell me what it is. Each polyp is about 2-3mm in size each. Any info would be appreciated!

Thanks for your help!
 
It looks like blue sympodium and it will be blue under any lighting.

It is more common in blue w/green polyps and the color will change on this combo with lighting.
 
blue clove polyps. sometimes called Japanese blue clove polyps. i'm not absolutely sure the species name so they may be sympodium also , but "blue sympodium" is often a bit larger and less invasive (and can have other colors mixed in). but these specific buggers are tiny, blue, and once established grow like mad. single polyps can and will drop off and start whole new colonies elsewhere in the tank. but they are quite pretty. i like them, just be prepared to put forth some effort to contain them before they get out of hand, or your whole tank will be covered in them.
