My beardie has gotten this tail discoloration after his recent tail shed. He has been darker here since I first got him, but now it seems more prominent. What could be wrong with him? Does anybody have any suggestions to take care of this at home? People are quick to say "take him to the vet" at the sign of the slightest issue, however that is not something I want to do if it can be resolved at home. I'm not opposed to taking him if it is serious and cannot be fixed without a vet's help. All of his behavior has been normal, and the area doesn't seem to cause much discomfort. Thanks
