Post pics of his tank, it just looks like he scrapes it trying to get under something. It could also happen outside the tank, can you think of him scraping to get under something ? It doesn't look serious, might just need some neosporin or raw honey if that's scraped.
Thank you for the advice I will send a picture of his enclosure tomorrow because he is sleeping right now and don’t want to disturb him. I let him out of the cage but it’s in an area where he cannot get hurt and he is supervised. I am relieved that you think it’s not that serious. I will try to put some neosporin on it. Thank you again. You have put my mind and heart at ease.
I agree, that does appear to be scraped up skin. A lot of dragons like to squeeze their
body through crevices, etc & end up scraping the scales up like that.
If you have any raw, unpasteurized honey you can put that on the area, daily, at night, so
that it stays on. Just be sure that there aren't any bugs that might be attracted to the honey
left in his tank.
