Welcome to the site!

You really need to warm the cage up a little. 88-92 F on the hot side, 78-82 on the cool side. Humidity needs to be between 40% - 60% normally and 60% - 80% during shed.

Do you have a under tank heating pad?

What are you using for hides?

A BP sitting on the cool side can be normal but it can also be a sign that something is off.
