Adult iggys need an enclosure that is around twice the size of them across and around six feet tall. Iguanas need tall branches to climb so yeah they need a pretty tall enclosure so they get enough exercise and are not bored
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
