About a month ago I picked up 4 RES about 5 years old each. They are doing great in my outdoor pond that has lots of plants and basking areas.
My question has to do with their care during the winter. I live in Northern Calif. (San Jose) and we don't get snow, but we may get some frost. I figure I'll need to get a pond heater (any recommendations?) to keep the water at the right temp. The pond is about 600 gal.
Do I need to do anything else? Can I keep them outside in Calif. all winter as long as I heat the water?
Thanks for the advice!
Mary
