Ya your right it wouldnt be a good idea, the main thing being the pond isnt deep enough. I refuse to put non-native frogs such as bullfrogs or green frogs, as they are not found in Saskatchewan. I don't think I will put any frogs in. If I did, it would be either boreal chorus frogs or wood frogs, bit I most likely wont put any amphibians in unless I remodelled my pond.
