Aw. It looks really sweet Tim.
I know that Tara Edwards raised her juveniles on fly larvae, I've always just handfed mine with chopped earthworms. They don't seem to be as sharp in getting the food into their mouths (I do notice the tongue coming out at times), but they do show enthusiasm.
They don't seem to be that picky, as long as it moves (slowly) and it fits into their mouths, they are perfectly fine with anything. I went on vacation for 3 weeks and left a batch with my friend on a white worm culture and they were fine.
