Fuck it, repotted it. It's in a 3.5gl or so pot.. Not 100% sure on size, but definitely bigger than the 2.5 and by a good bit. I want to find one more bigger pot and do up the Frisian - I'll keep the NL in the 2.5 since it's smallish anyway.

I did it quick and lowest stress possible. Cut the other pot off of it and slid it right in the new one. Less than 3 min total.
