He would seem pretty underfed for that age. My guy is between 8-10 months and weighs 450g. And he's not the best eater.
Try feeding him IN his regular enclosure instead of moving him. Most people here feed that way. He might still be anxious due to the move. You could also try feeding him a live mouse & see if he'll take that. Get a digital kitchen scale to keep track of his weight. He can eat prey that is as wide as he is at his widest part. I would try feeding every 4-5 days. It could also be that he just decided to go off feed. It seems to be the trend right now. Just keep offering & keep an eye on his weight.
