I recently changed the setup for my ball pythons terrarium and have noticed that he is much less active. His original setup was in a 20 gallon tank with reptibark substrate and 1 log hide. I had him in that setup for approximately 3 weeks. He would hide during the day as usual, but he would come out almost every night and cruise his cage (except for 2 to 3 days after he eats)

All I changed in his setup was I built 2 really nice hides (I vacuum formed my own hides out of copoly) that were dark and low so he would feel safe, and I removed the reptibark and replaced it with paper towel substrate. After I made this change i never see him come out of his hide (except to move to the other hide) even at night I don't see him come out.

Is this a good or bad sign? Could it be that he just loves his hides so much that he doesn't want to come out? Or is he afraid to come out for some reason? Is this normal behavior for a BP to stay in their hide all night?

Side note he is still eating like a pig so that's not affected.

Thanks for the advice
