What coral is this?

[Pyrobocaj08]

The stuff right behind the crab that's all long and flowing. Any help is greatly appreciated. My buddy is having me take care of his tank while he is in Afghanistan and this is my first sw tank. It looks like it's disturbed and has been all closed up for the past few stays.

Looks like some type of xenia or star polyp.
