The size difference isn't to much as far as I know. The pastel is about 2.3 pounds and the albino is 3.2 pounds. I had them both sexed and they are both male. The original snake that the pastel was housed with was a little smaller then him. Do know if that makes a difference.
Also just tried to feed them. I put a rat into there enclosure, which I NEVER DO. They are normally feed in a separate box. But just to see if either snake was willing to eat at night versus the day. Now both of them are on the other side of the tank wanting nothing to do with it. It's like the rat is diseased and they are running from it. They have done this to everything that I have put in front of them since Nov.
