I was moving my hatching snow from the feeding tank to his habitate and he had slither through the hole in cocohut (I moved that too since he's still a little freaked by the feeding tank). When I saw he had slithered through the small hole in the top I stupidly thought "Perfect I don't even need to touch him to get him back to his tank. I'll just pick up the whole thing." (He's still a little freaked out when I pick him up, he's only been with me a couple of weeks.) While I was moving him he slither out of the hole and fell to the floor. I managed to pick him up and he seemed a little scared from the drop but other wise fine. He's so small it was hard to tell if check for broken ribs. My hope is that he is so light that the fall did no damage. The problem is that I don't know what to look for. What are the signs that he might be hurt?
