First impression is a maricultured Acropora parilis, that has been fragged, and growing in captivity for about 6mos.-to a year.
Note the barnacle in the first pic,...Mariculture
Note the thickness of the main vertical branches, it's "open -ocean- maricultured growth form",.,.then the small pointy growth/axial coralite,."bushes"(tank growth form) blooming from top, where I would guess it was cut/fragged,...........................wow,..too much coffee for me this morning!
