I have a black tail cribo sold to me as as CB Male. He is between 4-5 Ft. He seems to be settling down a little more as i use to have to leave him alone to feed, and just the other day he took a small rat off a pair of tongs after a small game of tug-of-war. I may be letting him go before my next semester starts but i'm not entirely sure yet. Just thought i would let you Dry enthusiests know first. lynex17@hotmail.com
