Why is this important when a pond containing goldfishes freezes over in winter?

Answer 1

Providing the pond is not too shallow the ice will only freeze on the surface. the fish then move to the lower depths of the pond where their metabolism slows down and they live in a semi- state of hibernation. Your fish should have built up fat reserves in the summer which will see them through this cold spell. Once the ice thaws and the water warms the fish will start eating again. Remember only feed your fish in the summer and stop once the cold weather arrives and you should have healthy fish that will live quite happily through the winter. This answer is right as far as it goes, but the main problem can be a lack of oxygen available to the fish and other wildlife, especially if there is rotting plant etc debris (which can give off toxic gases) in the pond. I would recommend researching this topic more thoroughly if you don't want to risk losing your fish!PS This is Gipsygal speaking - I didn't provide the first answer, just added to it. Not sure how to make this clear! Oh well, I don't suppose it matters, no-one will read it anyway!
