Took a walk around the pond today and found thousands of dead tadpoles along the bank. They are the greenish brown tadpoles and are of all sizes. There was not a single one yesterday evening when I fed but today thousands. Did not see any fish just tadpoles. Is this a sign that my water is getting to hot or the do to low or something else. Anybody else have this happen? I have not used any pesticides at all and have not had rain to wash anything in from other places.
