Do horny toads eat fire ants or grasshopper?

I found a baby toad and i was wondering if they ate black ants because that is all i could find... please answer. They eat a variety of insects. Ants, grasshoppers, crickets and earthworms. If you are truly concerned about the toad, just let him go. They hunt during the day and in the summer, at night. He should be able to survive on his own.
