If argentine tegus are not fed sufficient fruit, theyt end to have issues shedding(as per other owners I've talked to, and the minor experiance on my own). I feed more fruit than meat, overall. No veggies, becuase frankly I got tired of cleaning up veggies that were tossed out of food dishes.
I started my hatchling tegus last year out on finely chopped apples and grapes, and ground turkey, with insects. They did quite well. I started my original tegus on the same, and moved them off insects, and onto whole prey as soon as possible, and they've done stunningly well.
If you'd like a more detailed listing of the typical diet mine eat, I'd be pleased to run it down for you.
