Listen to Zoodiver, he knows his stuff. I would go with a dwarf or spectacled caiman because they stay small, feed mice and chicks and pinky/fuzzy rats because rats have more nutrition than mice. Like Zoodiver said, fast him atleast one day a week, but I would feed every other day. Temperment all depends on the animal and the keeper's dedication. Anyone remember Bubba? He was a great gator, really sweet. That is my in the mustang hoodie, back before I destroyed the car. RIP Bubba, and my mustang.
