Thanks, BCR. She's in a 20 gallon long display tank and is 9 months old. Substrate has been paper towels from day one. Using an AcuRite with remote sensor in the tank, as well as a VE temp/humidity probe. The VE currently reads 55% humidity in there, which the probe is dead center in the tank. The AcuRite reads 52% on cold side and 59% on warm side. Pics coming soon.
