Ok, I used to have thme in my cichlid tank and they were AWSOME. Kept the tank clean and the only time I saw them was at night when I turned the lights on. Now, planning a planted tank, one of the first things I thought was to add these guys, as I can get them free, their live bearers, and they stay out of sight untill the lights go off. Now, after seeing so many posts with people trying to get rid of them, it brings up a single question. Why get rid of them? I realize that my cichlids used to eat them (VERY noticably, due to ther ammount of crunching you heard at night), which kept there population under controll, but are they bad for the plants? I was thinking of adding a loach or two to my future 7g planted tank to help alleviate their numbers a little, but it seems everyone wants to anihilate them completely? Is this just a prefrence issue, or should I stay away from them?
