A week ago I moved my beardie into a 40 gallon tank. Everything's been good except the humidity. The gauge on the tank reads almost 50%, but over his basking spot I've recorded about 25%. He currently has a 100w basking lamp. The gauge that reads 50 is half way up on the warm side of the tank. He hasn't been acting any different from it... I will be getting an 18 inch UVB soon, maybe that will help? Is there any way I can fix this problem, if it's even a big deal?
