I haven't had it long enough to honestly tell, but I think as far as pellets go both are okay.
I will say the reason that I'm wanting to feed mostly the jello shots is because I know what's in it. I don't like how many fillers are in any commercial pellet. I mean, honestly, what turtle in the wild is supposed to have wheat meal and soy? Fillers are always the first three things listed it seems, unless the food is something extremely expensive and has only freeze dried ingredients. The next up on the list is what should be in it, like the proteins and such, and then you get a bunch of I don't even know what. I know gelatin isn't exactly a wild food either but from the research I've done it seems to me, since it's made from the bones of animals, that it would be closer to something they might have in the wild. Such as in eating small fish. I might be crazy, but it makes sense to me.
This way he's getting protein, veggies greens, and a lot less of the "other" stuff that make up a commercial diet. (Sorry if I seemed to be ranting, it's just a subject I don't fully understand in animal or people food. haha Except for the fact that it's cheaper to make. That I get.)
With man, some things are possible. With God, all things are possible.
