We have a new Tokay and he is maybe 2 or 3 months old. He has been fine for the month we have had him, and then tonight he just fell off the side of his tank. Now he will breathe and get huffy but even when we touched him with a stick he didnt move like normal, but he did open his mouth at us. He did land on a piece of wood. I just need to know if it is common for them to fall off the sides of the tank like that??
