Well there are a few things to me are not as they should be.
The first being two snakes in one tank. Unless you are breeding them, which I hope you aren't because they both look very young, you should house the snakes separately. Ball pythons are not social animals and do not benefit by being housed together.
Second would be the half log hides. For a secretive snake like a ball python, half logs just don't cut it. Exo-terra makes a rock cave type hide that looks very nice and is suitable for ball pythons.
Third, the accurite placement. The probe should be right on the glass where the uth is. The probe should be completely under the substrate. you need to measure the hottest possible spot the snake can possibly get to to prevent thermal burns. Wouldn't want to toast one of those beautiful snakes! The rest of the unit should go on the other side of the tank (cool side). All those dial and gauge thermometers are useless, you might as well throw them away.
Other then that I think it looks like a job well done![]()
