Hi...I have a red-ear slider hatchling, and he was doing very well. Now someone gave me a diamond back hatchling. I put them in the same tank as the diamond back was started in fresh water, and the man who gave him to me said he can stay in fresh water. I was just wondering if that was ok to do. Can they stay together? My little slider doesn't seem too happy. He was very curious at first, and now he doesn't seem to want to go near the slider too much. Thanks for any info. Terry
