There's lots of posts on this site about introducing gliders. I recommend you search it and read a bunch, to get a nice wide perspective of the different opinions.
Here's my two cents:
I had some trouble introducing two of my gliders. The girl went after the boy. So I took a step back and started over. I had them in the same room, but the cages were far apart. I swapped pouches about every three days or so, so that each pouch would soak up all the scent possible from the one glider before putting it in the other glider's cage. I did that for about eight weeks, and without washing those pouches (sounds gross but it wasn't that bad). By the end of the eight weeks I believe the scents were completely mingled and each of the gliders had the mingled scents on them. When I finally introduced them, I did it in the bathtub in the middle of the day while they were tired. I offered a clean pouch which they eventually crawled into together. I put them in a small, clean cage for the day while I watched them carefully and cleaned the big cage so it would be neutral territory when I put them into it. That night I watched them again and for a couple weeks after I used a baby monitor to make sure they were getting along. So all in all, I got the boy in January, tried to introduce them after the 30 day recommended quarantine and two weeks of scent swapping-it didn't work. Then did what I described above, and finally introduced them again in April. It worked that time.
So i recommend
1. Separate the cages. Sounds like there's some aggression across cages and that won't likely get better on its own.
2. Scent swap for a longer time. I don't know if you did the 30 day quarantine, but either way, try to give it a few weeks. Especially since they've already balled up.
3. I'm not sure exactly what steps you took while introducing them, but I strongly recommend neutral territory like a bathtub, and doing it during the day. Offer a clean pouch if they seem to get along, and a clean, neutral cage as well.
I don't remember if you're new to the forum so just in case, welcome!
Best of luck to you. Try to be patient
