Hi all! I'm posting out of concern for my ball. I bought him on Saturday from a reptile expo in Portland, OR. Even before buying him, I noticed very faint differences in color on some patches of his skin. Small amounts of flakey scales are around the edges of these patches, as well. Is there anything I can do to help him? Is this a sign for a possible health risk?

Pictures to follow (when it is daytime). Thank you!
