ok so my new little tegu is a hungry little guy, how hungry do you ask? well i gave him a pinky that was pretty big and he greedily wolfed it down and i figured that would have kept him fed for a while but no an hour later he wanted more so he pounded down 4 criks and i think 3 meal worms. anyhow i want to get him some roaches i know they are suposed to be good. now my question is since i see hes gonna grow fast, hes already shedding,what size should i start him off on and since they seem to come alot for a little should i stick to a small size or should i get a combination of small medium and large knowing hes gonna grow into a larger food item soon ?
