i got a red footed tortoise about a week ago, since I’ve had him he’s always had little snot bubbles and make clicking and squeaky noises when he pulls his head into his shell. I thought it was part of his personality until I read the snot bubbles may be a sign of a respiratory infection. He has a huge appetite and isn’t showing any signs of sickness apart from the bubbles and noises. Can someone please tell me if I should be concerned? (Tank and tortoise pics included)
