I am having a hard time with the humidity in my beardies tank at night. He's in a room approx 20'x15'. I have two 33 pint dehumidifiers within 3' of his tank. Room AC at 73 degrees and the humidity in his tank is still 60 in the am. He is acting differently, Not eating. I believe because of this. I took him to the vet. Vet says all is fine. We're in Georgia. What else can I do to get the humidity down. Will a ceramic heat bulb make it too hot at night? Thank you in advance for any help!
