BLUE TONGUE SKINKS

Hi guys, so I checked on Monty the other day and I noticed he had a scar on his head, I homely don't know how he got it, there is no above the tank heat source anymore. I'm hoping it will come off with the next shed, but he is not eating lately because of winter.

Could be he scratched it on something; doesn't look like anything requiring special care unless it turns red or seems to spread. I bet it'll look much better after a shed or two...
