Hello, and welcome!
I think you've found the best place on the web for support with collared lizards. You made a great choice in getting collareds. Of all the lizards I have kept over the years, they are my favorites. They're such charming little critters. 
I am not surprised at the apparent condition of the lizards you got, but I am little worried. I have seen a few look pretty rough at pet shops before, and have even bought them just to make sure that they got proper care. Did yours come from a pet shop? Ero looks pretty sick to me. My first suggestion would be to get them both to a qualified vet who has experience with reptiles ASAP. It is probable that they have parasites, and most likely have not been housed under optimal conditions for a while.
Though I am sure that you will "meet" Eve soon (if you haven't already), I do want to refer you to her website for the specifics on collared care.

Best of luck with your new charges.
