Enjoy your Water Garden in the Winter. The fish are still there but very inactive. You all should know by now that you do not feed your fish in the winter. Rule of thumb...if the water temp is below 50 do not feed. The poor little guys will eat if you feed them, you have trained them so well. But, the high protein fish pellets are not easy to digest in cold water, which would be fatal to your fish. If not running your pump/fountain in the winter, make sure you have a heater in the pond. This allows for gases to escape under a ice cap. We are all about making sure your fish survive the winter!
