I did check with the previous owner and she said he's always eaten during a shed, so i'll just wait a couple days and try again.

If it is live food, try again in a week after he sheds. ALWAYS supervise live feeders..
Yes, i would honestly prefer to be able to feed him live, however because of where I live that is not an option. There is no pet supply store where I live and the nearest one is 4 hours of driving to get to, one way. I end up having to order in bulk bags of F/T. 50-100 at a time.
