Hi,\nCan anyone help me please? We have no frogs and consequently no tadpoles in our pond this year. As my sister had millions, literally, I took a couple of scoops with a jug and transferred some of hers into our pond. Whereas in her pond the tadpoles were on the surface when I transferred them they seemed immediately to go to the bottom and I haven't seen them since. There are newts in our pond and pond skaters happily skimming around on the top.\nCan anyone offer any suggestions?
