It depends on the food, the size of the frog, if it is full grown or not, etc. Typically younger frogs should be fed every day to every 2 days with crickets, mealworms, nightcrawlers, etc. Older frogs should be much less, with adults eating once every week to two weeks. Basically you have to judge how much your frog should eat. If the frog starts to look fat, cut back on feeding. If the frog starts to look skinny, then feed it more often or in larger portions. It is a sort of objective deal. Good luck.
