Ok, so, I've had two Beardies for about a month and a half and they are both completely different. The one that I am concerned about is acting very strange. at first, he was fine, for about the first three days he was completely normal. Then, one day, he fell asleep. It almost seemed as if he began to go into a brumation phase. I found out that the problem was insufficient heat. I went out and got a higher wattage bulb and he woke up the next day. Ever since then, he has become jumpy if I try to pet him, he runs around the perimeter of the tank when I walk into the room. Sometimes, if I put my hand in, he even gapes at me and puffs his beard. I try to put my hand in the tank every day, moving slowly of course, so that he gets used to me, but nothing seems to work. Now, he will even go after motion in front of his tank and try to eat my fingers through the glass. He is just a juvenile BD and I am worried for his health. He eats fine, his light and night light are fine, he gets water, vegetables, it seems to be a social problem.
