Columbian Tegu

[siz]

We have been offered a juvi Columbian Tegu. Does anyone on Ssnakess have one? I noticed Coy posted about one last year. I'd like some opinions on housing and temperment and stuff. I've checked out a few care sheets but I haven't been able to find an exceptional one, if you have any links they would be much appreciated. We have an 80g we can put it in, and have a mesh 6'x3'x3' which is perfect size for an adult. Would it be stressed in the 80g due to its large size? Offhand I can't remember the length of the tegu, probably about...5"?
We have some spare things lying around. We would be using cocohusk for substrate. We have a hot rock, ZooMed I think - should we use this? I've heard a lot of bad things but this one doesn't really get too hot to the touch, although I can't even estimate the temp. Obviously I would have a basking spot too, just curious about the hotrock.
And what do you feed yours? I've read a few different things so I'm not to sure on that. I've read that half of their adult diet can consist of fruits and as youngsters they should eat mostly a large variety of insects and pinkies.
I think that's all for now, thanks.
