I don't think a betadine bath is needed. You have a young male which appears to be a bit stressed (which is normal under the circumstances), but otherwise healthy. I would suggest you to change newspapers for a substrate (mixture of peat, sand, gravel,or similar) at least 2-3 inches deep.All terestrial lacertids have strong psychological need for digging and not able to do so can get them very stressed, especially specimens like yours which grew up under semi-natural conditions.
