I wouldn't worry. One feeding is certainly nothing to be afraid of. This time of year, many balls will go off their food. Some won't eat again for 2-6 months. Others will not stop eating throughoout the winter.
You can try to feed him every other week if you'd like. He may, or may not eat. If he was healthy before this missed feeding, there shouldn't be anything to be concerned about. However keep an eye on him. Make sure he still looks healthy. Look for anything that could the reason for him to stop eating.
