The problems is my snake want eat and that research here has determined it may be from temperature, so here is the current setup.

I have a Ball Python in a 20 gall long tank. He is about 30" long. I am concerned about the temperature in the tank. I have an UTH on a Hydrofarm Thermostat. Our house stays on the cool side (68 deg at night). As the cooler weather approaches the temperature has been dropping a little further down. I have noticed the drop in temperature so I have added a heat lamp above the tank. The ambient temperature under the light runs 75 deg. The temp on the hide holds about 90-92.

My ball will only eat about every 2-3 weeks and I feel that he should be eating more. I understand that the lights are not the best options because of humidity. I felt that I needed to add the heat until I could find other options. What other options do I have to property add heat to my tank other than raising the house thermostat? Is the any other information that my be beneficial to you guys?

Thanks for all of your assistance and I have learned so much from this site.
