I think that is Cali Tort - also awesome, and that's a very nice frag from
@JVU (I think most people would prefer that over the little dragon dildo looking Oregon tort frag you got from me!).
The big giveaway is the green - Oregon has zero green anything. Cali tort (and miyagi) get neon tips sometimes, and some darker green hues in the flesh between corallites.
Cali tends to be branchier and have more knobby growth, whereas Oregon is a little smoother and uh...pointier? Oregon is a little bit of a brighter, more vibrant blue. Really stunning when they are healthy - one of my favorite corals all time. And they grow slow AF.
Here are pics from my tank.
