ID help please

[thrillreefer]

I have a couple colonies of this coral that I got from a friend who had forgotten what it was. Grows quickly, and has shown up as "spontaneous" colonies in a few places in the tank. Because of this, I am leaning towards it being a Pocillipora (planula propogation). The colony on the right was recently broken, and the white is the interior of the colony with clear polyps. Does anyone have a definitive species ID they can give me here?
Here it is under 20K halides:

Heck, while we're at it, I'd love to know what species of Acropora I have here (if anyone knows)....

A pic from 9 mo. ago:

And a recent pic, you can see a couple of branches that have grown over recent frag points

Looks like Tri Color
Acropora Validia ( my spelling maybe a little off here)

Yeah, it tends toward tri-coloredness when it is growing well: greenish-brown base color, purple growing tips with pale green (almost white) terminal polyps. Otherwise it stays a drab greenish brown. Frags do well though
