Hello everyone, I’m John. I live in north Georgia, USA. I have a 1,000 gallon, 4-5 feet deep pond underneath a large waterfall. The pond has a pump and a skimmer at the pond level, plus a bio filter at the top of the waterfall. I have also installed a secondary pump in the bottom of the pond that has a UV lamp to help ensure no green water. Two air stones help the falls, and many water plants keep the water aerated. I keep Comet Goldfish, White Cloud Mountain Minnows and Rosy Red Minnows in the pond year round and they thrive in even freezing temperatures. They have all produced fry many of which have also survived the winter. This summer, I introduced to the pond six guppies (2 males and 4 females), four albino and two peppered corys, all of which seem very happy. I’ll move the guppies and Cory ‘s inside for the winter. The guppies will be easy to catch, but the cats don’t come up much, except during occasional feeding times when they sometimes come up to a shallow stone shelf to see what is causing all the commotion. Has anyone over wintered Cory’s in a cold pond?
