Noooooo my snakes are not housed together [big no-no]

They are atleast 2yrs old, Huge guys both at 4 1/2ft not sure what their current weight is, but i know they are healthy. They are in sterilit tubs, with their black hides, and heating pads.

thanks everyone for the advice! I do keep records on everything they do. So hopefully he just wasnt hungry this week
