I just moved my RTB in to a new tube a sterlite 41qt. The humidity is around 75%. I want to bring that down to the normal 50-60%. I moved her water dish to the cool end already and that did not help. I was thinking of two things 1) drill more holes in the tube and 2) maybe get a smaller water dish the one she has now is around 9 inches across. Any thoughts would help. Thanks in advance.
