I don't have a tegu but I have thinking really seriously about getting one. My blue tongue skink died and I was thinking about getting another one when I ran across a vid of an argentine tegu and I have been obsessing every since. I have had reptiles off and on my whole I life so I understand lighting etc... I am not a big fan of fighting with humidity, and I think that hurt my blue tongue, but I would likely spend the money for a fogging/misting system to lower my maintenance.
Overall these guys don't seem like a great deal of care and what I really like is that once I spend the money up front to get the enclosure set up I can spend more time with this guy than I did my blue tongue because I can let it roam without the fear of getting lost, though I do have two dogs so it would be a progression. For my blue tongue I used to make all kind of mush with meat, eggs and vegies along with some fruit and that is what I would expect to feed this guy along with maybe some frozen rodents.
Anyway I think I have good idea of what the care looks like for these guys but feel free to weigh in.
