Coral ID please!

Got this from a local reefer who didn't know what it was either, but it looked pretty cool. The picture makes it look more purple than it is, it's more blue. It is NOT a Teal Stag, he had one of those in his tank and that's not it. Any help is appreciated! Thanks in advance!

Blue stag?

I dunno, I'm asking you all!!

seems like a stag just guessing from the knobs what do you think? Is it a fast grower?
