First of all, Id like to thank all of you for your quick responses. Ive had him for a solid 3 weeks and he has eaten all 3 weeks. He still hasnt shed yet but is starting look a little cloudy and dull. His temp on the warm side stays at 90 F all day and all night. The humidity hangs around mid 40's. I have the hardest time keeping it up around 50. I know it should be but its so difficult to do for me. I use repti-bark substrate, it seems to hold the moisture in for a little while, but by the time i get home from work its right back down to the 40's. I have him in a 20 GAL. long tank. I have a non-light emitting ceramic heating element and a UVB light on top the screen lid of the cage. Whats the best possible way to keep the humidity up while Im at work all day?
