Thanks for the replies everyone! I will definitely get him some bigger food, I figured what they were feeding him was kinda small, cause I know you can feed them stuff as big as the biggest part of their body, and some people say you can even feed a little bit bigger than that, I just didn't want to try switching up his food right after purchasing him to give him time to settle in.
The tank I use is a 30 with a screen top, which I cover about 50% of the top with clear acrylic to help keep in humidity. The substrate is Eco-Earth which really helps to hold onto moisture. He currently has a large ZooMed Habbahut on his warm side which stays around 90F which is warmed up with a ZooMed heatmat that goes under the tank. I control and monitor the heat with an Apollo Horticulture Heat Mat Thermostat Controller which is usually for plant heat mats but works perfectly fine with the ZooMed and has a probe that goes with it.
He has a second hide coming soon that I will be putting on the cool side, along with a new ExoTerra Hygrometer since my old one is kinda broke. I also ordered some Sphagnum Moss to put in the tank that should hold some moisture in it to help with the dry air. He also has a large water dish. My biggest issue is probably the humidity so I've been misting the tank almost everyday when he isn't out exploring his tank.
They had warned me he was underweight for his size, so I asked them to give me all the data they had on him for his eating habits. I've been following for the most part their same feeding schedule. Feeding Chart. I kinda experimented a little but decided just to stick to every Wednesday so I didn't pester him about food, but I am worried! I will feel a lot more at ease once he finally eats something.
Let me know what you all think!
