Juvenile not eating, help!

[Geminiluna]

I thought that he would for sure eat now so I went and picked up a rat pup about 25 minutes ago and held it in front of him for a few minutes but he had absolutely no interest. He was more interested in climbing onto my hand than the pup..

I assume this was a live rat pup? Did you leave it in the enclosure, turn off the lights (or cover the enclosure) and walk away for any amount of time to give him a chance? Some of them can be shy about eating, and may not show interest with someone nearby.
