I actually have a school of 4 royal grammas in my 125g. There has been a lot of controversy on whether or not grammas would school. In my experience they will if you get them roughly the same size(very small to somewhat small). I originally started out with 6 grammas, 4 small size, 2 medium/large. The two larger ones were trouble makers, chasing any other gramma they saw so I had to take them out(no easy task btw). The 4 I have all hang out around the same rock structure and never fight. Hope this helps.

i think they should be a hareming fish. I have heard that you can keep one big and few small ones... I would try a small harem instead of a pair
