Anyway, he has always been sniffing and sneezing regularly which I learned is just him clearing out his nose after digging, which seems consistent with what's going on with Bima, and I also learned from this site that whistling every now and then is no big deal which happens to him. But sometimes when I'm handling him, he'll do the sniff-sneeze and it feels kind of wet? Would that be classified as discharge?
He doesn't seem to have any issues breathing and he's very active with a voracious appetite, but I've been very uncomfortable with it since he's the only one of my pets where anything like what he's doing can be considered normal so I'd just like to be triple sure haha! He is in a 48x18x18 tank, 95-100 basking spot and 80 on the cool side. His humidity gauge reads around 40-50, I have a misting machine and when I put it on higher, the whole tank gets foggy, so I guess I'm also wondering if that'd be ok for him too? He's on a mix of cypress and coco fiber right now but on my next day off I'll be cleaning his tank and doing only cypress since he greatly prefers it.
And last but not least, pictures! These are from various ages
And one of my drawings for fun
