Well, they are easy and hard to keep...
The biggest thing for them is to have the diet correct, and UV lighting.
They also will need a very large enclosure when they are grown as well, with plenty of ventilation and warmth.
Quite a few also don't reccomend them as pets due to their needs and a lot of times, their attitudes later on, such as males during breeding season, etc.
Also, it has been reported in many magazines and sites that lizards, iggys especially, don't get along with female humans during the humans menstrual cycle.
Thier bites are also a lot worse than snak bites in just the amount of flesh that is shredded if not completely torn off.
just food for thought.
