In my display, they pretty much are where they are until they get shaded. Then I will remove and put them through a light acclimation process. If I am diligent and slow with that, they come out OK.
In my high energy frag system, the small colonies and frags are constantly being moved, knocked over, blown around. I have oversize tangs in there too that knock stuff over all the time. Purely anecdotal, but I feel like they do get a better uniform flesh tone and polyp coverage in this more dynamic setting.
