I have my tank with my 6 year old female(toff) and the temps and humidity have been great, right on, then i check last night and the humidity dropped to 26% nothing on the setup has changed, the only thing i can think of is the room temp has gottin a little cooler at night. i have a 6inch x 4inch x by 2 1/2 inch deep water dish in there over the uth. what can i do to raise it up like i said i but the dish over the uth? and have the 75 watt infrared light over the water.
