My girlfriend and mother have a serious phobia of snakes and I have been thinking about selling my BP to a friend that is in love with it as a trade off for my girlfriend letting me get a tegu. I want to do some research on tegus long before I decide to buy one. Housing is the main issue. How big to tegus get and how long does it take until I need to upgrade its enclosure? I can build a cage no problem but I just need to know what size it would need at what age and what is the biggest cage I will need. What do Tegus eat and how often? Any other advice would be great too thanks.
