Do you have any links that can be referenced? Sorry but I don't see how rice and bread fit into it. As juvies they're more carnivorous, some of the big breeders say they flat out are carnivorous as hatchlings. I don't feed meat primarily, when my tegu was younger he would eat mostly meat with some fruit and failed veggie attempts (daily). Now it's more fruit and some meat with it, he eats about every other day. Most of the time the veggies just get thrown around.
I've seen this link passed around a few times, if my gu wants to eat some spiders I'm all for it lol.

I guess more or less I feed things off of this list. It's posted on another forum as well and has a lot more responses but I'm not sure if I'm technically allowed to link it. Sooo here's this one

There are a lot of debates on tegu diets, some people even feed a diet that is almost strictly whole prey.
