Hey guys!! I am here with a question about my male Red Eared Slider. He is being super aggressive to my other turtle, Zoey, who is a 3 inch pink belly side neck. I can't put them together because of it. Zoey needs a bigger tank, but my rooms floor won't allow another large tank. I have decided that I want to build an outdoor pond for my RES. The thing is, how will I teach her to hibernate? I am worried that she will let herself freeze because she won't know what to do. He is about 3 years old and hasn't been hibernated through any winters because I wasn't planning on moving her outdoors. What do I do? Please help!!
