Hello,
I have 3 10-year old RES in an outdoor cement pond. The pond is about 500 - 800 gallons. I live in Southern California. Last year, we almost lost one of our turtles with a respitory illess. They were outside all year and mid winter we found one in distress. We needed to give our little guy shots for over 6 weeks to get him better.
I want to leave them outside in the pond this winter. They are too big to bring in. Do I need to heat this pond? They can get out of the water on to rocks but don't have anything to burrow into (like mud or sand). Can someone give me good advice on leaving them outside. I am getting different info from all over.
Thank you.
