You need to check with a local reptile shop, Petco, Petsmart or any place that might sell fruit flies or pinhead crickets. If he is too small for the normal size small crickets that most petshops carry then he is a gonner if you can't find some fruit flies. But you can also order fruit flies from the internet from one of our sponsors like Joshs Frogs. He will send you out some right away. However, as someone said before if you're not willing to spend $5 on a petstore frog we can only hope that you are willing to pay something in order to feed it.
