Leopard Gecko not eating! D:

I recently bought two new leopard geckos. I've had the new male for 2 weeks, and the new female for 2 days. The male however has yet to eat since I got him, and the female is already eating well. I don't know why. I've offered him mealworms, waxworms, superworms, roaches, and crickets (He may have eaten 1 cricket, but I don't know for sure.) and Im worried about him. He's got plenty of warmth, humidity, calcium, etc... He just won't eat. I know its normal for leos to take a few days to get used to their new habitat, but surely two weeks is enough time? He was fat and healthy when I got him, so I know I didnt just recieve a sick leo or anything... Any help would be greatly appreciated.

I got him eating today, he will only eat crickets, despite being raised on mealworms. Thanks anyways
