My friend sent me this picture of a pets for sale group on Facebook and wanted to know if I thought that tail looked necrotic. My own beardie had tail necrosis before I adopted her and it looked similar as far as discoloration but it didn’t go nearly as far up as this one appears to. To me it does very much necrotic ,but I wanted second opinions. If the tail is necrotic he’s going to look into contacting the people and bringing the little guy to the vet.
