The netting we put on the pond to keep the leaves out in the fall is still on our pond. There are no holes or damage in it. Recently we discovered all 30 plus of our gold fish are gone. The pond is as clear as bath water so we can see to the bottom. There is no sign of our fish or their remains. The pond and fish have been there for over 13 years and we have never had a problem before. What a mystery! It is like they dissapeared over night as there was no sign of the population going down a little of a time.
