We ordered them off the internet. They looked good when we got them, there was no indication of them fighting, and they ate for a couple of days. They one by one, they started laying on the bottom of the tank, floating upside down, and on their side. The one by one they died. We do have one left and he is looking good so far. I am glad the online store had a quarentee. We are afraid to add any more fish but the tank looks empty. I didn't think it could be the water because our blue star and everything else is doing well.
