But I think I should argue that owning a pet is a relationship. If the owner isn't happy, then how can he care to keep the snake happy?Not sure you will ever be happy than because that's what they do, BP spend 80% of their time hiding, so you might want to ask yourself if a BP is the right snake for you.
You need to get a digital thermometer/hygrometer to allow you to get an accurate reading, you can use something like thisA glass thermometer shows the temperature under the light at 95~ degrees. The middle of the tank is about 75-80 depending on ambient temperature and the far side is a bit cooler than that, around 71.
You also need to maintain proper temps and not allow those temps to fall below 75 degrees.
Note: The thermometer above is also a hygrometer and will give you an accurate reading of your humidity level.
