He's up and about again. During the daylight hours, he will be in his hides, but during the night he is exploring his tank.
I want to say that it's because, other than the slight hiccup of the UTH which can be easily rectified, his husbandry is otherwise flawlessly following my expectations, so he feels safe enough to explore his space during the night, when he is awake. I am worried I am wrong.
That being said, the activity isn't something I'm used to, and typically changes in behavior are considered odd, right?
