She is my first ball python so I want to make sure I'm doing everything right. I have had her for a bit over 3 weeks.

She is in a 20 gallon long tank with a screen top. Her hot side fluctuates between 85 and 90, while her cold side is 75 to 78. The tank is heated by a ceramic heat bulb.

The humidity is in the mid to high 50's.

Just want to make sure that it all sounds good, or if I should be making some adjustments.
