Picked this frag up at the LFS. Not really sure what it is. Its purple with bright green tips. The branches are smooth with the polyps out at the rounded ends. Seems to like lower light. Sorry the pic isnt better quality. Any help would be much appreciated.

It's really too small to give a good guess. Maybe Acropora aculeus for an initial guess. But it could be a lot of different species at this point.
