Kind a looks like mine Sorry don't know the given name, was just told it's a deep water acro. The common of these uncommon species are Acropora caroliniana, Acropora multiacuta, Acropora granulosa, Acropora lokani, and Acropora suharsonoi.
Well I'm torn, it does look like Tricolor Valida although it also looks a lot this Silver Bullet Bonsai. I'm leaning towards the bonsai but still not 100%, what do you guys think? Here's another photo for a better look.
