I've raised these frogs from tadpoles I rescued from a oily patch of water in a ditch last spring they have gotten along fine togather but 2 of them have slightly differnt patterns on thier back, the smallest of the 3 has very round spots, im pretty sure its a leopard frog. I've looked at tons of picture of leopard frogs and pickerel frogs and can't seem to get a clear identification. The other 2 don't have blocky spots like pics of pickeral frogs I've seen a few of thier spots look more like lines. And I don't see any yellowing on any of their thighs. Can anyone tell me for sure? I've heard pickerel frogs should not be kept with leopard frogs since pickerels are toxic but they have gotten along fine since they were tadpoles so I'm hoping they are all leopards.
