Do you Gus think that my red eared slider will do well in a pond next to my house? Because he is getting big and my other one is too. They are healthy and I think they will do well what do you guys think?
If you have the space for a nice sized pond, I say go for it. Just make sure that it is secure from predators and escapes, they are good escape artists.
RES get so large I personally believe they should be kept outside anyway.
