Looking for an ID on this acro

I picked this up Saturday from a local club member as a "Purple with whit tips something or other" I'm looking for something a little more specific.

Looks just like my Purple Slimer, an Acropora youngi ? will take a quick look to make sure stating correct species

Cheers, Todd

It's not Acropora yongei because it doesn't have the same radial corallites. It looks closer to Acropora arabensis, which is from the Red Sea, so very unlikely. But a start for my guess.
