that looks like a nice tenuis....slightly saturated pic IMO though.
On a side note if one store in the states has one frag they call blueberry acropora why should you assume everyone knows it? If you google blueberry acropora there are lots of different corals being called blueberry acropora.
On the same note I have named some of my corals but I don't expect everyone to know what they are. Im not ranted just on the OP but I see this quite often. I mean some corals have been in the hobby a long time and are well known but ones like this one.....unless you went to reefhotspot and saw this frag for sale you would have no idea....and the chances of that are slim. I only know cause I googled it and saw the same pic amongst many other different corals.
as an example here is vivids "blueberry" acropora

Hree is spikes "blueberry"

I could go on.
