The black and white ones are a male and female Anerythristic Kenyan Sand Boa het for "albino" ( i dont know which is which tho) and the orange one is a normal Kenyan Sand Boa female. There so cute and a lot different than any other type of snake ive seen. I was a bit annoyed at fedex tho because they arrived at 10 and i got home and took them out at around 12 and the box was upsidedown, he/she completely ignored the giant red arrows.
