I haven't tried prepared food before and frankly I don't plan on trying it. From what I've heard in a lot of cases, the frogs hate the stuff and spit it out. Besides, it's better for the frogs nutritionally and provides more roughage if you just feed them whole prey items instead of what kinda seems to be dough with fish meal in it. I wholeheartedly agree with what Ryan said as well-the frogs should be allowed to do their natural feeding behavior instead of basically being force-fed stuff they apparently won't even like. That's my two cents and I hope it helps!
