What kind of toads are they and where did you get them from? Also, how big are they? Please post a picture of them if you can. Small frogs can eat fruit flies or small crickets depending on the size of the frog. Those can be purchased at reptile shops or Petco or Petsmart. You really need to check out the care articles to ensure you've got your bases covered....but first we need to identify what kind of toads you have.
