What is this on my GSP Frag?

[Varsity09]

What is this light purple stuff growing/spreading on my GSP Frag? It has not yet opened and not sure what it is since I am new to coral. Should I be concerned?

If your referring to the white stuff, it's most likely a sponge .

Looks like a sponge. If the coral is not expanding normally a soft tooth brush to remove the sponge works well.

I was wondering what that white bubble was, but now I am wondering what that purple stuff at the bottom of the frag is. Looks like slime almost?

Here is another picture. I should of circled it before. Is this still a sponge?
