he is in a 20 gallon long tank, one side has a big water bowl where he can submerse himself at anytime, i just put that in since i noticed his left eye started to dent because of dehydration. (someone told me no humidity). The side with his water is the cool side, roughly 90. The right side has a big hide for him, a heat pad under for a solid core heat and then a 60w bulb on top in the middle of the tank so it gives the water evaporation for humidity and keeps the hot side above 92. I try to clean the mucus off the sides everyday and switch his paper towels every other day. The heat light is on 24/7 since it is a night bulb and he gets daylight from the sun. No drafting what so ever. Am i doing this right? Please let me know.
