Hi, I have a ball python that's around 4 months old. I got him in the beginning of May. He's in a 20 gallon(long) acrylic tank with a glass lid to keep the humidity up. The ambient temp. is currently 83. His basking temperature is 88. Humidity is 55, can go up to 65 when he's in shed. His tank is heavily planted and decorated with lots of driftwood, vines, leaf litter, plants, etc. He has 3 hides, one on the warm side, one on the cool side, and one that's in the middle. His substrate is repti-bark, a layer of sphagnum moss, and leaf litter on top. I've seen him use all his hides and he generally hides during the day and is active at night.

Yesterday I fed him a mouse(frozen) and after eating it he's been having some strange behavior. He took it no problem and ate it immediately when I offered it to him. After eating it he laid in his hide on the warm side for about an hour, and then was suddenly very active and roamed around the whole tank for a while, probably 2 hours of constant roaming. He then curled up underneath one of the pieces of driftwood. It's been about 24 hours and he's still laying there. I was worried he was dead, so I lifted the log. He felt very stiff and didn't respond much to touch. He moved his head a little but besides that, no movement when I touched him or lifted the log, which is strange for him because when I normally reach my hands in the tank(which isn't often) he's very responsive and will usually periscope to see what's going on.

He doesn't seem to be in shed, his eyes are his normal color and his belly isn't pink. I'm concerned because there have been no issues the entire time i've had him, he's never refused a meal or had any problems shedding. This was also very sudden. The mouse was the arctic mice single large mouse from petsmart. He;s too small for rats so we're still on mice. Anyway, any ideas?? I'm very worried for him. Thank you.
