I have a colony of 6. Gus is the boss man. he will sometimes chase the
others for a trip across the floor, but not very often. I can hear spats
in the pouch from time to time. first thing they eat is the corn, and if one
glider has a piece another glider may cause a spat trying to steal the corn piece.
same goes with live or dried mealworms.
I don't see it often, but I have seen one of our neutered males try to mate
with a female.
so I cant say what is going on with your gliders 100%, but it does seem they
are just being gliders. In the end if neither one is getting hurt you should
be ok.
Your gliders sound small are they getting enough food, do they eat it all or
is there leftovers. (could be my gliders are just fat, some are fat.)
