I have read plenty of threads on this forum saying that using a 7ltr sistema tub will be fine for small snakes. I have a baby spotted python in a tub with a heatcord covering roughly a 3rd of the tub covered by aluminium tape and newspaper on top, the thermostat is set to 32degrees which is what i was told by the breeder, the water bowl is down the Cool end of course. There are plenty of holes in the tub for air. When i checked the tub before i noticed the lid is fogging up above the water bowl. Is this bad?
