A: Use tokomak or some other solution to simply solve it by having collisions protect them from merging.
B: Each loop check distances between each of the monsters, if they're withing a threshhold, move them away by a percentage of the threshhold they managed to break.
[Edit] That's very true, spheres whouldnt move through one another m8. So standard blitz collisions should do this for ya :).
