I purchased a melanistic eastern garter(Darth) in August, and when he arrived he was roughly the same size as my T. s. infernalis(Obi). As time passed Obi continued to grow at a pretty noticeable rate, but Darth seemed a bit stagnant even though he was eating consistently. I kind of put it off as the difference between two different species. As some of may know I went on a two week vacation and as I was prepping the snakes for their time alone I realized there was a major size difference between the two. It was to the point that I was worried Obi might confuse Darth for a prey item. Needless to say I separated them, but I am concerned that there is something wrong with Darth. He has gotten a bit more finicky about eating, he eats but refuses to eat anything but worms. This could just be a product of the season. I also don't think this is the issue because he was not growing well even when he was eating whole pinky mice. Has anyone else had this experience with this species or in general?
