Some day I'd like to get some Dart Frogs. The food supply would be the most difficult for me, and I was trying to think of alternative ways to get them food instead of solely using fruit flies or culturing them myself.

So I had this idea of setting up the tank and putting in some female crickets in there, and letting them lay their eggs and removing them later. Assuming I kept doing this, and I could figure out the time frame from laying the eggs to them hatching could this supply say two or three Dart Frogs with an adequate food source?
