In dec. 2018 my beardie has been lazier & lethargic. In december the temperatures dropped down about 1-3 degrees Celsius. In January they dropped down more, about 3-6 degrees Celsius, 2x more than the last month, but the temperatures inside the room had been quite the same as normal. Since then, I usually find his sleeping under the basking light, and today he had a black beard while sleeping for some minutes. Then it all went normal. When I wake him up or make any weird movements around him he wakes up and goes back to the normal itself, active for some moments and with a great appetite. Then he just lays back under the basking light and sleeps again. Is it possible that although the temperature in the room hasn’t changed he can feel the cooler temperatures outside and as a result is behaving lazier? He has a exoTerra 125w Solar Glo and a 10.0 zooMed reptisun. This has never happened to me before, specially with that 1 time with his black beard... I’m starting to get very concerned, specially being such a paranoid beardie owner.
