Hi, my name is randy and I'm interested in Argentinian Black and White tegus. I have a floor plan of a full size enclosure measuring 6x4x3 LWH, I was wondering if I purchased a newborn tegu, at what age (or size) would be good for him to be when entering this cage if not from the get go, and if not, what should he be in until he is old enough to be put in there
