I recently took in a young adult iguana and have no idea how to care for him/her. I have a 20 gallon long with branches but i know its not big enough i will fix that today. I can handle the food and humidity and temps, I guess the big question is, how do I tame this little bugger. Everytime I open it up hes out running around the house at full speed running head first into walls. He won't even let me touch him with out freaking out? HELP
