Fish
Keep your outdoor pond fish from becoming "fishsicles" in the winter!
With cold temperatures just around the corner, now is the time for dedicated pond keepers to begin preparing for winter's storms. Sub-freezing weather can be hazardous to the health of your fish and plants, but with a little planning there is no need to fear the cold.
Inside or out?
The biggest question facing a goldfish pond Pet Parent is whether to bring fish inside for the winter or leave them in the pond to weather winter in underwater hibernation. After more than a thousand years of domestication, Goldfish and koi have become well adapted to living in small ponds. As long as an outdoor pond is deep enough, these hearty fish can get through the harsh winter weather with no problems.
If there is a chance that your pond might freeze all the way down to the bottom, though, you'll have to net your fish and bring them inside until spring. For some Pet Parents, this is a chance to spend time with their fish, feed them and get to know them better. Be careful--your fish may take more space than you first expect: that six month old goldfish you placed in the pond last year could now be twice as big! One thing to keep in mind is that the glass windows on a regular aquarium are for people, not the fish. To save money, there is nothing wrong with wintering your fish in a cheaper, plastic container.
Sleeping the winter away outdoors
If your pond is deep enough, your fish can comfortably sleep away the winter under the ice while you dream of spring from indoors. As long as there is enough space for your fish to sleep under the ice, they should do fine all winter long. In most of the United States water does not freeze deeper than two feet, but ask a knowledgeable ice fisherman to find out for certain how deep water freezes in your area.
Goldfish go into hibernation when the water temperature drops below 45 degrees, so they won't mind having a little less space to swim in or less to see. They barely eat or move. You should not feed your fish once they go into hibernation. You can even turn off your water filtration device, or switch it to low. All the Pet Parent really needs to do is to make sure that there is always a hole in the ice where air can get through. If this hole freezes over, toxic gas won't be able to escape from under the ice and it could kill your fish. You can prevent a freeze-over by floating a ball or some other device on the surface of the pond, or by using an electric heater.
If the hole in the ice freezes over, do not try to chop it open. A force such as this could send shock waves through the pond that can potentially injure, and even kill, hibernating fish. The better way to open a hole in ice is by heating up a cooking pot on the stove, and then setting it down on the pond ice.
Autumn cleaning
With tree leaves fluttering down, autumn is also the right time of year to spend extra time clearing accumulated debris from your pond bottom. Fitting a net over the top of the pond can reduce the amount of leaves that get in, but you will probably still have to scoop debris off the bottom with a net. If the sludge has gotten deep on the pond bottom, maybe it's a good time to vacuum that up, too.
The approaching winter does not have to be a slow time for dedicated pond keepers. The fish may be hibernating and the pond may be covered by a foot of snow, but you can always start mapping out changes and improvements for your pond for next spring!
