He's about a year old and I've had him for a few months. Before that, he lived with my dad. The temp is around 80F, he lives in an aquarium, and he's about 1.5-2 feet. There's a piece of wood that my dad got from the pet store inside the tank and he likes to hide under it. He also likes to empty out his water bowl and hide under it. Also, there's a lamp with one of those .. reptile lights shining on one end of the tank, and there's a humidifier set up and turned on for a few hours at a time every day. If I leave it on too long, water starts to drip off the sides of the tank and such.
Also, I feed him a one or two little feeder mice every other week.
That's how he's been living since I've had him. Before, my dad just had him in the tank in front of his television, without a light and .. anything else, but his piece of wood.
