Thanks! The encouragement that it will be okay is likely what he needs to hear the most, so thank you for the kind attitude. I guess it's hard to help him out when we are long-distance friends.

@Alter-Echo Do you have a picture I could send him to prove it's just a tailtip and will be fine? He's a real worry wart.
Unfortunately, I dont, and I no longer own the snake, but the vet had me follow the same iodine soaking routine your friend is doing with this snake and the tail formed a clean scaleless nub on the end, and far more of the tail was missing than on this snake.
