There is no dumb question! You only learn by asking questions! Now you learned something new so it wasn't a dumb question! That python was probably "vicious" because it was stressed! It has no hide and no covering on the sides and back of the tank! He will probably settle right down in good husbandry! As to the males being females, I would get a second opinion! The chances of a breeder mistaking a female for a male is extremely rare, nevermind happening twice! Males sometimes get mistaken as females but if you seen hemipenes, you know 100% it's male so they breeder must have seen the hemipenes to label it male! If the breeder made a mistake that bad, he really needs a lesson on sexing! What is his name? I would like to buy some females at male prices!
