I have read a lot of articles about the hillstream Loach on the Internet and I am really confused about they're keeping. Some articles say they are Coldwater fish and some say they do all right in a tropical environment. Can anyone out there tell me if they have one and what kind of environment are they keeping it in. I would like to get one but I have a tropical environment set up and I do not want to get one if this will not be suitable for him.
