My Spider is acting funny. Last night about 9 pm I cleaned his whole cage and kept him in a box for 15 mins till it was done. Afterwards he picked a spot on top of his hide and he hasn't moved a muscle, literally, in almost 24 hours.

Here's a pic of the exact position he's been in all day.



He usually spends all day in his hide and then becomes very active at night. Sometimes all night. Which of course, seems normal. This is why this new behavior is so odd. He often climbs to the lid and falls several times with a thunk! I figured what can I do to stop him? If he wants to climb and fall, he will. But I wonder if he got hurt or something.

His hot side stays around 90-92 and the cool side is a little low at 75 but I've heard that's not terribly bad as long as the hot side is good. I top off water daily and clean/change substrate and water once a week. I handle him once a week for 10 mins.

Any ideas what's up with him? He's eating great and at 100g after only 5 meals.
