A friend out herping found a group of three small water snakes, two blotched water snakes, and one diamond-back water snake, all non-venomous, all very well behaved and easy to handle, and all about the same size as the garters in my baby-tank.

Although the herper who found them states that the water snakes take basically the same care as the garters, and that a deep water dish is all they require in a dry tank, I'm not sure how well they'll all get along.

Does anyone have experience keeping garters and nerodia together?
