I picked up my 7 month old Leopard Tortoise 6 days ago and have him in a closed chamber with 80% humidity and 80 degrees ambient temperature. His substrate is a layer of coconut coir topped with orchid bark. He has a shallow water dish he stomps through regularly, he is eating well. I take him outside for about an hour a day to get some sun. I soak him in warm water twice a day for 15 minutes. Yet this morning I noticed clear fluid bubbles coming out of his nostrils! He ate breakfast as usual and is active, however I want to make sure I do whatever it takes to help prevent a respiratory infection. What should I do? Thanks in advance.
