My BP's Behavior

[Annarose15]

I have a electronic thermometer that measures humidity and both temperatures on the sides of the tank, as well as a thermostat connected to his heat pad under the tank that is normally kept at 89-90 during the day then 80-82 at night on one side. The humidity is reading about 50% and as for lights, since I have the heat pad, I keep his tank close enough to the window so he gets daylight without getting direct sunlight, I figured that'd be best. He is currently in a 10 gallon glass tank with all but 1 side blocked so it looks enclosed, and the top has a mesh screen.

This is a red flag to me. Why is your hot spot dropping so much at night? Did you mean to say that this is your ambient/cool side temp? Your temperatures should be fairly consistent from day to night. What is your cool side temp?

As far as his behavior, though, hiding is what BPs do, especially during the day. He is striking simply because he is intimidated by you. They almost always grow out of it, and it doesn't have to be caused by anything more than you being an enormous "predator" to him.
