Short tails are SUPPOSED to be smaller.. but I saw one of Kara's that was as big as my brongersmai.

If you really want one, pick the one that you like the most. They're all decent sized snakes, but not giants by any means.

Like any snake, there are snippy ones and docile ones. Most become docile with age and handling. Mine like to hiss but they're pretty docile otherwise.. well except for my new one. lol
