Before you start to worry yourself gray I would read through this: http://ball-pythons.net/forums/showt...f-Up-About-IBD

Your best bet is to keep an eye on him for a while. If you were quarantining correctly I think it's possible that your mojave could just be stressed about moving or hungry. I highly doubt at his size that he's interested in the females near him. I keep my males and females in the same rack and my males don't act any different this time of year. I do have two hatchlings that are very active at night when they are hungry (as early as a day or two after feeding )
