Acropora species identification?

[Nano_reeflover]

I was kinda on the fence between soli and valida as well. I can say that my frag of this colony has full polyp extension from all corallites. Here are two pics of my frag. It's a little bleached out right now, but you can see it's picked up a nice green color to the base and is getting the purple back in the tips. I've had the frag for about a year now.

yes what you have pictured is A. valida, but if you look closely it is different from the OPs coral.
