I've kept a small one (ca. 20" SVL). He was bolder than the similar-sized yellow-belly and diamond-back that I had at the same time; he didn't burrow in the litter like they did, and wasn't skittish. He accepted handling fairly well, and ate like a pig. I ended up being forced to give him away when I moved, so I can't speak to his long-term health.

You're right, they are gorgeous animals. Very high contrast pattern. Sorry, I don't have any photos of the little guy.
