Do tree frogs eat crickets?

Question

I caught one and im keeping him in my tank, idk what to feed him.

Answer 1

It eats pinhead crickets, no bigger then the size of the distance between his two eyes. He will eat other small water bugs, and fruit flies.

Answer 2

They eat flies and little bugs that are in pond water, not crickets. Let the poor thing go in the wild where it belongs.

Answer 3

Yes, they do eat crickets, and nearly any other small insect. You shouldn't acquire an animal until you know about them. Wild caught frogs don't do well in captivity. The best thing would be to release him where you found him.
