Canned food? I usually caught and raised my own food.

This summer I raised all of the above mentioned animals from tadpoles. (I somehow got a peeper tadpole while scooping my bucket back in the flooded woods behind my house collecting water. I heard a bunch of them calling but never say any.)

I started out with live food and then switched to canned once they all became used to hand feeding. It's real easy to get a variety of food this way and its easier to dust the food with calcium.

For the toad I just put him in a plastic container and drop food in front of him. He'll look at it for a second then snatch it up.
