Tank Update:
Here is a picture of the current setup: https://imgur.com/a/X6HJSPF
I have added a 60W CHE on a hanger controlled by a thermostat. Thermal probe is mounted in the middle, but slightly off to the warm side (along with the CHE). My old thermometer is mounted closer to the cool side. Ambient temps set to 82 degrees F to achieve a range between 80 and 84. Metal screen doesn't get hot at all, but ambient temperatures are within check now.
New water dish holds a little more (less refilling) but has similar water surface area. Old water dish holds some moss to increase ambient humidity. Place-mat above areas not occupied by CHE to keep humidity in until I can get out for some foil. Still waiting for these to have an affect on humidity as I just put these in a few minutes before writing this.
I will continue to watch my numbers closely and wait a week before trying the defrosting and feeding strategies dakski recommended. I think I am going to opt for the hairdryer method so I can scent the room a little more and hopefully pique his interest.
