I also agree, Make sure all temps, and humidity is good. Then leave them be for a week. If the small one bothers you because he is a little thin then try to give him something after 5 days. Feed no bigger then the largest part of their bodies. For the thin 50g guy i would try a prey item at 10% of his body weight. So that would be a 5 or 6 g rat or mouse, i prefur rats, but thats me and rats are easy for me to get where i am.
