My cousin found a RES in his yard 11 years ago. "Myrtle" lived in a 10 gallon aquarium for the last 6 years. We just built a beautiful 20 x 20 pond in our back yard. So Myrtle came to live with us now. She is loving life! She is very active, eating very well, and basking in the sun on rocks daily. My question, since she was indoors for the last 11 years, should we bring her in for the winter or see if she hibernates on her own?
The bottom of the pond is river rock, the center is 3 feet deep for the fish, and we will keep the waterfall running throughout the winter. I don't want anything to happen to her. The walls are too high for her to escape. Any help would be appreciated, thanks in advance.
