Hey Danielle! I dont actually have a pacman yet. I am getting one- but I do own other animals and I think I have a few tips regarding the humidity that may help. First of all what type of lid are you using (if you are using one)? Typically people use the wire mesh lids that will often come with tanks. I will usually put a wash cloth over the top of these lids and will leave some of the lid uncovered which will allow air to still flow through the tank. This will usually keep the temp and humidity at a stable level until you may need to spray the tank again. You can choose whether or not to soak the cloths If you wish. The eco earth and water dish should be enough to help keep humidity at the proper level. I guess if you really wanted to you could get an automatic mister that will self regulate a set humidity in the tank. But those can be pricey. Hopefully the experts on here will correct me if im wrong about anything. Anyway good luck! Best wishes to you and your pacman!![]()
