Hello! so a few days ago i saw my hatchling tortoise blow one bubble out his nose, so i thought i will take him to the vet so i was going to take him but the i noticed he hadn't been doing it anymore and it was just one time so i waited a few days to see if he did it again so to day i saw him do it once, i still don't know what to do about it his nose is not runny and the bubbles are clear he has only don it once that I've seen what should i do?
