The garter commune

[adamanteus]

If feeding times are very closely supervised, the only other issue, as Udo has already stated, is the possibility of unwanted matings. But generally, on a day to day basis there should be no problem.

Personally, I keep all my species/sub-species separately.... but that's just my preference.

I also prefer to keep them separate. Its just easier for me. I used to keep a few garters together, and feeding time was a headache. Different species seem to have different levels of feeding aggresiveness, so one just pounds the food, and looks for more, while another needs a little coaxing, but by then, the first one is attacking the second one's meal...
But if you separate them for feeding, and they will still eat ok after being moved into a different container, then it can work ok. The only garter I am familiar with being potentially dangerous to cagemates would be western terrestrial garters, if they are bigger than the others, although feeding accidents can happen with any snake.
