Dipso's are the "Dwarf monitors" of the iguana family.
Very cool animals!
However, as someone I know who has them told me:
They need A LOT of space!
These are desert dwellers, very well known for their speed (just look at their rear legs), so they need plenty of space for running and chasing prey.
I'm talking Green-Iguana space (obviously withouth the height).
Good hiding spots because they are wary lizards.
Play-ground grade sand (for kids).
Very hot basking spot.
Kaplan's link as provided in the other reply is excellent.
A common mistake is to think these small igs can go with a small enclosure. Wrong. These are fast moving iguanas, who need plenty of space to roam and thermo-regulate between the quite hot basking spot, and the cooler areas.
Free-roaming is tricky, due to their size and quickness. A tame animal will do fine, but always be careful of course.
Keep us updated!
