Size of cage?

Question

what size of cage should i get for a adult waterdragon

Answer 1

It needs to be at least 2 x their total length - so you are talking min 6 ft long (side to side), at least 2-3 feet deep and 4-6 feet high to do it right.  Water dragons are semi-arboreal but also need enough water to submerge and swim comfortably in, as well as branches for climbing, and plenty of ground area for roosting and feeding.
