My beardie is approx 8 months old and has a spot on his tail. It is small, but I am not sure if he had an injury or some sort of fungus/issue. He is currently w his 6 month old "brother" and they have never shown any aggression (at this point) and we are getting ready to separate. Any thoughts on this?? Debating on taking to the reptile vet or wait and see. He is otherwise healthy, eating normal, etc.
