Perhaps I should have posted this in the health clinic but not worried with health. Earlier today when I hand feed my male (the usual). He got back in his cage on the basking branch. I noticed his mouth slightly open. With the door still open I hunched down a bit to get a better look. His body semi puffed and he blew out what appeared to be dust clouds from both nostrils. I examined him after he looked fine. The salt build up on the insides of both nostrils where now clear. I have seen my previous male do this but am unaware if this is normal?
