since mine were little they have a home in my greenhouse and we have them a pool right outside of it for them so swim...but....now that they r bigger and we want to introduce them to the pond it is hard because they are soo used to the greenhouse and pool...lol...so the day that we took them down to the pond to try to let them swim and were scared to death..i told my boyfried..ok that is enough...they dont wanna go into the pond yet...so i think what is gonna happen is when they do finally wonder further from the greenhouse and they find the pond and swim around they r still gonna come straight back up to the greenhouse and sleep...which is absolutely fine with me....i am willing to share my greenhouse with my poopy babies...geez do they poop..lol...
