Heating and tank help

[Malum Argenteum]

She hasn't eaten with me at all. I got her beginning of July. I have very vague info on her from previous owner, so it might be as long as 5weeks.

Had the snake eaten for the previous owner? How many meals? What was it eating, exactly? What is the hatch date of the snake? Did you buy it from the person who bred it? If not, where did that person get the snake?

More details will help to figure out what to recommend, since it may be that this snake may never have eaten.

Not probably what you want to hear, but a proper enclosure (PVC with a heat panel, or a tub in a solid sided rack) leads to snakes that are more likely to feed reliably.

It may be worth troubleshooting why the snake is hanging out up high. Could you post a full-tank shot, and get some temps with an IR temp gun of the different areas in the enclosure, and give details about the heating equipment?
