Iguanas are reptiles so they need heat lamps rocks or trees for them to bask. You'll also need a UV lamp so he can get vitamins. Like most reptiles Iguanas need hide holes so they can feel secure. They also need a biggish tank because they get to be 12- 17 .in. Iguanas are not as friendly as a bearded dragon that's held normally but they like to be held so hold them normally.
