Thank you for the kindness, I was very attached to the little guy; not only he was my first garter but also my very first snake! Not really the best way to start... So you think that could have killed him?
As it was my first experience I'm still a bit obsessed if I've done something wrong caring for him after all, do you see something wrong from my welcome thread? I was still housing him in the same conditions, and feeding him SMALL sized guppies every second day. So, did that last bigger(but still medium) sized guppy contributed?
