#1 T.radix - Plains Garter, for me their calmness is a big factor. They adjust to captive life and seem to enjoy it. Each snake has it's own personality and once they trust you they really trust you. They are great eaters and seem very hardy.

#2 T.ordinoides - Northwestern Garter, Great personalities.

#3 T.s.parietalis - Red Sided Garter, Have many of the radix qualities.
