Do you have experience with lizards? If so what kinds? And how have you had experience with them?
If you are asking questions about the animals basic husbandy, you are not ready for it.
Before you even think of getting one, you MUST have:
an adult size enclosure built BEFORE getting a hatchling
a plan for feeding (not asking parents or assuming you have enough)
have a plan not just for the animal, but a plan for housing of yourself.
Be able to recite its care etc. Like the alphabet.
Thats just the tip of the iceburg too. Just keep researching until your eyes bleed and beyond.
