I have three(i fear soon to be two) three day old garters and their mommy garter, caught wild(unkown age), approx. 16in. I have a 30"L X 12"W X 13"D tank and a 13"L X 7"W X 10"D tank. How should i divvy up the snakes, and when if ever should i change it up? Also, does anyone have any thoughts on releasing the mother back to the wild, since she is understandably anti-social? The three or two surviving babies ill keep and raise in captivity. Thanks in advance.
