Foxface's are extremely neurotic fish; they have a tendancy to startle easily, and when scared they'll drain nearly all of their coloring from their body and dart around the tank.
They Do posture with their spines, but like others I think its a sign of fear or apprehention. I've never been stung by a foxface, but the guy at my lfs has, he said its sort of like a bee sting on crack, with the same nasty side effects of hospitalization and death if you are allergic to them.
