Yeah, I am struggling to keep the temperature above 80. I live in Indiana, so the weather outside is changing constantly. I have my heating pad underneath now and hopefully it will help. I'm afraid to buy more than two heating pads. Seems a bit ridiculous. But my frog looks healthy still. I mean He is still fat haha. The tank he is in now is a ten gallon. I have the top wrapped 3/4 with aluminum foil. Here is a picture. I dont know maybe he is too small for the aquarium right now.
