My tort has never had any mucus come out from his eyes or nose-the last few days Ive had him in a large plastic container outside so he could enjoy the fresh air-last night I picked him up to look at the bottom of his shell and when I turned him rightside up he snorted some musus-clesr-out of his nose-this was the only time Ive seen this-hes eting and drinking fine-should I be worried-any advice appreciated
