I have three turtles that have been living together for a while. Two of them are Florida Cooters and the other is a Red Eared Slider. A couple of weeks ago I got a SS turtle that I absolutely fell in love with. I have kept him separate since he is still so tiny. I am in the process of making a pond for the bigger turtles in our yard because they are getting big and I want them to have more room to swim around in. I was wondering if it will be safe for me to introduce my SS turtle into that environment when it is older, or if the other turtles will attack it. I would never forgive myself if something happened to Sheldon (that's my SS's name)because of a mistake on my part. Does anyone have any advice?
