Thanks everybody, just bought betadine, NIX, lice bedding spray and a bunch of other stuff and he is soaking in the betadine solution now. I placed him in a spare tank with paper towels as soon as they dropped him off and put everything they brought with him outside and poured bleach water in it. Pretty much everything that he had with him is useless to me anyway since maybe a tadpole could fit in that water dish and they were using a heat rock! Also of course not a hide in sight and no belly heat. Poor guy has stuck shed all over and scales that are obviously pushed up by mites as well as retained eyecaps. Hopefully he will be looking much better soon. The only thing that isn't bad is that he does look like he has been fed properly so at least there's that.
