I have a LTC pair of SDs from Bob Clark. They are both under 10ft & are very cool snakes. I recommend a CB SD male if you like smallest length possible. My male is very tame, however during breeding season he cares more about getting with his girl just like a typical Retic. It's cool to have adult Retics that feed on Med-Lg FT Rats.
I hope to produce some more eggs like last year AND this year see them hatch too! Baby SDs are smaller than BPs! They are also very active snakes when they are young, I like to offer them hides & a bit extra room to explore. They are also FAST movers! When working with them I find slow deliberate motions are best, at least at first.
Please make sure to get familiar with the LOOK of SDs, they are different than the mainlands- if in doubt get pics before you buy & post them up. We'll help you.
