i think with northerns it doesnt matter if there the same sex they can still snap,ive only just got them,first time keeper of them,well i have an adult female broome phase kimberly northern to that ive had for a few weeks as well,but yeah, not sure why northerns do it,ive seen plenty in shops and people who keep them out doors ect where they have room to get away,still can suffer from northerns getting narky,and nipping off tails ect,its not all of them though,but happens enough to be careful when there together,heres my kimberly female northern i got from perenty7,shes a doll,beautiful skink with a beautiful temprement
