I’m going to buy a bigger enclosure and don’t know if a 40 gallon tank is big enough for my male gecko, he’s around 10 inches. I also don’t know what type of substrate would be good for the tank I usually do paper towels but want to switch it up and don’t know what would be a good heat source for the Substrate to get through the heat pad.
ADD— Also if I was to use some sort of sand like desert sand would I have to clean it? N how would I go about that
