Is there a reason his tail looks like those I can’t tell if this is normal or there’s a reason for it I got him a week and a half ago and he is my fist one ever and wanted to know if this was normal or not
His tail is injured. It could have been bit by a cage mate before you got him.
It appears to be healing good. Keep it clean and if it becomes swollen or the wound starts traveling up the tail, get him to a vet.
Most likely its well scabbed over and will eventually dry up and fall off
