Questioncan bearded dragons and iguanas get along
Answer They can not share an enclosure because their needs are so different. Iguanas are tropical arboreal herbivores, they get a good calcium rich salad, need humidity, day temperatures of 96F and a tall enclosure the size of a double closet at least. A bearded dragon is a semi-arid/woodland fence omnivore, 8 foot square of floorspace, temps between 100-105F, and eat the same salad but need insects.
I do have beardies and I have an iguana. And I have friends who have both too. As far as sharing freeroam time, they can sort of get along as adults, although if both are male, it is a sort of David and Goliath relationship.
