So I just got a year old albino corn snake yesterday! I put him in a 40 gallon tank and he's staying burrowed in the back corner of the cold side. Is that normal? Also his hides are much bigger than him, he looks tiny in them. Should I try smaller ones to help him feel safer? He also occasionally makes this clicking noise when he's moving around, and he has his mouth open a bit pretty much constantly. I can see his teeth if I look at it closely. I only notice the clicking noise when he's moving around. Could he have a respiratory infection? I don't have a good picture of his mouth, sadly.
