Identify this coral please!

Well i went down to my lfs and picked up a frag. I think it is either GSP or pipe organ but it may be something else?

 

[speg]

GSP.
Pipe organ will form tubes (pipes) and it's why it's called "pipe organ"
GSP will grow a flat purplish mat that'll sprout tiny little tubes where the polyps come from. Very hardy coral.
