Don't let him hunt for the food... try either hand or tong feed the crickets to him or put crickets in a glass bowl wide enough for your frog to climb in and out of. Crickets cannot climb out of a clean, dry, GLASS bowl. Search glass bowl trick on here and you might find other posts about it. This trick was amazing till I started tong feeding my frogs all separately to make sure they all ate equal amounts of crickets. But if I still only had one frog I would still be using the glass bowl.
