I keep him in a 40 gallon screen top terrarium 36x18x16. His temps are currently 84 cool side and 91 hot side. Humidity is at 49 percent (really hard to maintain high humidity with the screen top). I use only aspen bedding and I switch his water out with fresh water twice a day. He has two hides both are clay planters. He only acts like he's ready to strike for a while after he feeds (medium sized rats by the way). Most of the time it's like he couldn't care less about sticking your hands into his cage. I just read somewhere that moving them into a new tank every time you feed them can help prevent what the site had called "cage aggression." This is the first python I've had in quite a few years and I didn't have my last one long because I had to move for my job, but that one was only a hatchling anyway. He struck at me once and got his teeth in which hurts like hell and I'm trying to avoid that with this big fella (whose teeth are signifigantly bigger) lol. I've done a lot of research on the husbandry and such but I'm no expert and there's no replacement for experience.
