When i first got my hatchling tegu in early october i fed him/her once a day every day,crickets,mealworms,waxworms,grass hoppers. After about 3 weeks i started feeding him/her ground turkey,boiled eggs,pinkie mice,ect, I was still feeding once a day everyday these food items. I then found this web-site {tegu talk} and i read that young tegus should be fed as much as they will consume in the first year of their lives. I started keeping the food bowl full all day long of turkey and pinky mice with eggs and the tegu has doubled in size and weight and sheds everyother week now, He/she also sleeps alot more to. HE /SHE is around 18 or 20 inches long and about 3 in wide and like i said has doubled in size. My enclosure is a 7'by3'by3' hot side 86 to 88 basking 108 to 112 cool side 72 and 74 humidity is around 58 to 65.
