Reptile Ventilation Fan, LED Digital Thermometer and Humidity Gauge Dehumidifier for Pet Rearing Box Reptile Tank, with Humidity Sensor, for Humid Environments, Rainfo-Rest and Ecological Tanks

7 cm isn’t really deep enough for these guys, you want about 10-12cm on top of the drainage layer. And then 2cm of leaf litter I also think your humidity is too high, I wouldn’t mist- you need to pour water into the wet area You may also want to get a fan with a hemostat so the air isn’t getting stagnant. I recommend something like this for the dry side, as you can set the humidistat so it automatically turns off and doesn’t dry the enclosure out. If you’re able to get another enclosure I’d get one that is longer- around 40cm for a really nice moisture gradient. The height on this setup is just wasted space. I’ve found Cubaris to really need humidity and moisture gradient to be dialed in. I have cappuccinos and they are sensitive

Mine is just a 5 gallon tank with window screen mesh on one side and a plastic piece on the other. The fan is around $18
