Hello, I recently got a new beardie, had a couple many years ago. I just finished building him a new enclosure. His basking spot is reading in the low 100s with a temp gun but his behavior indicates that he is not hot enough. He is always in the basking spot, his color is blacker than before, he keeps climbing up the wall to get closer to the light, and he is super grumpy. I have a 125 watt mercury vapor bulb about 10” from basking spot and today I put a 100watt basking bulb close to the basking area. He is still being weird any ideas of what is up?
