Its really hard to take decent pics of ball python
Im using thermostat n hygrometer temp 33 C hum around 40%, external heat pad 8 watts, big water bowl, cold hide, big trunks, bark substrate, cork on 3 sides, tank cm 50x100x50 plastic net top. Some parts of the cork were ripped off by rats and some adhesive tape was exposed. Im afraid it could be that.
