Smallest specie of Asian beaty snake (Elaphe sp.).
 

I was interested in working with some more asian rats and like the looks of the asian beauty snakes bust most appear to be out of my size range. I prefer snakes that stay under 4 feet. I'm leaning towards the trinket snake (elaphe helena) but I was wondering if anyone knew of any specie or subspecies that stay small or are smaller.

This thread is a couple of months old, but I just saw it and thought I would put in my 2 cents...

While nowhere near as small as a trinket snake, the Chinese Beauty Snake is (in my experience) the smallest of the Beauty Snake Species. Particularly the Calico morph seem to reach a shorter length than the other morphs; in my collection they tend to reach 2 1/2 ft - 3 1/2 ft in length, with some individuals reaching a max of ~4 1/2 ft.

Hope that helps!
