Same care as Colombians. I keep mine at about 50% humidity, 80-95 degrees. They are typically voracious feeders by nature. Some people may say they are agressive by nature, however many people mistake a healthy feeding response for agression. Hogs are in feeding mode 24/7 while in their cage I find. They may strike at the glass, but are typically ok once out. Babies are often defensive, and adults may grow up to be a bit hissy, but this is usually just a bluff. 5-6 feet is the average size, but it isn't uncommon for them to exceed this. Although some may be able to be kept in as small as a 3x2x1 enclosure, 4' is a better bet.
