    4 feet is adequate Providing your pond filtration system is effective your pond has been well stocked with plants and is well aerated you should not have any problems If the winter is particularly mild and the fish remain active feeding may be required throughout the period The rule is feed the FISH not the POND When in doubt do not overfeed as that simply adds waste to the pond Having said this owners and breeders do have different opinions about how to over winter fish Some examples of recommendations that Provet has come across include Bring the fish indoors in the winter House them in a deep barrel of water This may be appropriate for valuable Koi carp Add a heater to the pond surface heaters can apparently be bought quite cheaply Dead plants should be removed from the pond as they will rot adding waste toxins to the water If the pond surface freezes over entirely cut a hole in the ice to allow waste gases to escape Add a chunk of polystyrene to float on top of the pond This will prevent the surface from icing over completely and allow gases to escape It can be weighted down by attaching it to a brick Logs of wood added to the surface of the pond may achieve the same purpose and may provide an area of relative warmth near the surface of the pond Fill a plastic bottle eg a milk bottle with hot water and place it on top of ice to melt it Do not smash or otherwise break the ice as this can kill the fish sent in by a visitor to Provets web site Cover the pond with a sheet of bubble wrap sent in by a visitor to Provets web site Float a
