Hi, my name us randy and I'm interested in Argentinian b&w tegus, and I have a floor plan for a cage that will measure 6x4x3 LWH I wanted to know first if that's a suitable size for an adult, and second at what age (or size) should a baby tegu be put into here if not from the get go, and if not what size cage will work until he is old enough to be transfered
