We are having so much difficulty maintaining humidity for our girl. She is a juvenile, and we have her in a 45 gallon aquarium. We have sprayers, black light for heat, heating pad on the side, and a humidifier that sprays on a timer. She's in a basement room though that isn't especially warm. Trying to keep her between 70 and 80 degrees, with humidity at 70 to 80 %. We don't have cross ventilation, which I know is better, we have a sturdy mesh lid, so heat can escape there and for ventilation. Isn't working. I have 7 kids at home, my 15 yr old is the owner and he loves her dearly, but I've run out of ideas! And the pet stores know nothing.
