Whether they are fuzzes or hongkongs could the fact that they get along so well be because one's a male and one's a female, if they were the same sex (at least both male) wouldn't they fight as warty newts are supposed to. I'm beginning to think that I'll never be able to truly tell what they are unless I manage to breed them (which I have made my objective) and raise the larvae to juveniles, which from pictures on caudata culture and on other sites seem to indicate are relatively easy to distinguish.
