Very skinny ball python

Offering him the appropriate sized prey every 5 days is going to be your best bet.

I would also make sure he has a hide on both sides right now. Watch your humidity on the aspen - that bedding likes to suck the air dry pretty quickly.

Are you new to snake keeping? What is your heat source, and what are you measuring temps and humidity with?

To answer your questions yes I'm new to snake keeping my heat consists of heat tape under one end and a 75w ceramic heat bulb about 12"-14" above to help ambient temperature. to measure temps I have digital Thermometers with probes attached inside tub on top of the heat tape and a th-100 tracking temp/humidity on the side of the far end then I spot check with a temp gun
