Yeah he might be older... maybe three months?

I'm going to give it a few days and see what's up. The tank stays very humid as it is totally sealed (wooden top with low-wattage light inside). Some people have warned against keeping the bulb inside but this one doesn't get extremely hot and my ball doesn't mess with it. I'm thinking of drilling some holes in the top, though, to lower the humidity (which I've never measured, but there is almost always condensation on the side of the tank).
