I have placed him in a large hex tank. He can span the bottom 3 times over. I also have climbing areas for him. I have placed a small under tank heater in one area. He has water areas, in one of which I places several small minnows. He has already hunted and caught 4 of them. It was amazing to watch!! He has a place that he can go into (a rock) and I filled it with shredded paper towel. I sure hope he likes it. I could not find any proper worms for him, but I purchased some very small pinkie mice. Will try to feed those in about a week. I know they'll be too big for him, do I cut them length wise or just feed him the extremities first? I also have the tank in an area that stays fairly warm, about 72.
