UPDATE: I am happy to report that the smaller frogs has finally started to eat more than one or two fruit flies - he is up to 4-6 every night. The larger one continues to eat 12-16. I'm just happy for the improvement with the little guy. I think his problem is that he is one of those nervous frogs. Some are just like that, while others, like the larger one, are calm as can be. I think he will continue to eat more and more as he gets used to things.

I just want to thank all those who took the time to give me such helpful suggestions.

With much appreciation...
