I was watching my snake for a little bit tonight, and he was laying on this big branch i have in the tank and just had his head straight up with nose almost touching the screen. It seemed like he was stargazing to me, he stayed in that position for close to a minute. Although i dont see any bubbly mucous or anything coming from his mouth im still slightly worried. I'm hoping that he doesnt have an RI. And ever since i got him and up til now one thing i notice is that he doesnt seem to flick his tongue all that much, he does on occasion but not a whole lot while he's out and about. So im thinking about taking him tommorow. The exam is $65, but for peace of mind i think it should be worth it. :/
