i've got two RES that I saved from a friend that didn't want them any more and they only had a 10 gallon tank for them which is all that i have to keep them in right now. that is why it is important for me to get them a bigger home. i've decided to build an outdoor pond for them to live in. i live in CA so they will be able to stay out there for all but the cold parts of winter.
anyway my question is about making the pond turtle safe. i want to make sure they wont leave the pond, but at the same time i want the pond to have a natural look to it. there are many raccoons around my house so they must be protected from them. those are the only two things i need help with. i've got filtration covered and construction of the acctual pond won't be a problem either. thanks for any help.
