I just got a red eared slider. It is about 4 inches long. I put her out in a pond in my backyard. I live in the bay area in california. Are there any special things i need for the pond? Its 3 feet deep in the center and has mud and dead plants at the bottom. I made a latter so she can get out. Do i need to set up a pump to circulate the water? Do i need to heat the water, or will she be fine? When i feed her, should i just put collard greens in the water or what? I got her from a crappy petstore and the people didn't speak english well. Thank you for your help!
