Green ameivas are active, heliothermic lizards that come from South America. They need bright light for normal activity. Place a basking light at one end of the cage so that he can go back and forth between the heat and shade as he wants. These alert and active lizards need the largest caging possible. Cage temperatures should be 95 to 105 degrees Fahrenheit under the basking light; 78-85 F at the cool end of the cage.
