The small chain swords and, to a lesser extent, Sagitteria send their
runners on or above the surface, and these runners would go right over a
buried plastic fence.  Even if the fence were an inch above the gravel
surface, the pigmey chain swords might get their runners over it.  If the
fence is going to be effective, it is going to have to show.  Perhaps a 1/2
inch high fence with occasional trimming of runners trying to climb over
would work and the fence would not be very noticable once there was a good
growth of plants on either side.

Good luck!
