I'm sorry for your loss. I don't think anyone here is blaming you. You were told wrong things and from here you'll have to do your own research. Luckily, you've found a very good spot to do that!
I would consider switching to a tub for your next snake. I started out with a tank and couldn't get the humidity right so I switched to a tub and it's now perfect. I don't have to mist or do anything special. The water bowl keeps the humidity in a good range. Tubs aren't the best looking but I'm just using them until I can upgrade to PVC.
You can just jump right to a pvc cage for your next snake. From everything I hear they are awesome and it's much easier to keep husbandry up in them.
Take a look around. Keep posting. Everyone has to start somewhere![]()
