The dithers are dithers. They dont need territories.If I was setting it up, I'd add the dithers first and let them get their territories set up. Then add similar sized sev and con at the same time.
Serverums and cons can breed.I doubt the sev and con will cross breed.
I never stated that they couldn't, I stated that doubt they will.Serverums and cons can breed.
