That's my opinion: NOT to wait.I have a leopard tortoise hatchling that I bought at a reptile shop about 10 days ago, and like you, I noticed a bubble coming out on one side of his nose. The next day I took him to an exotic animal vet who diagnosed him with having an upper respiratory tract infection. He gave me the antibiotic Baytril with which I inject 10cc (via a shot) every day for 5 days and then every other day for another 5 days. Keeping my fingers crossed that he recovers. My advice is to not wait a minute longer getting him to a vet who specializes in exotic pets. Best of luck : )
