Thanks for your reply. I am sure that they are HBG because that is what was put in there four years ago...at least that is what they ordered four years ago. I am not sure if it is silt or muck, I am also looking to add an aerator and a fountain this spring. If it is muck, would this be partially reversable as far as the depth? I was told that this strain was only supposed to have a 15% reproduction rate. The fish supplier is through the county and they have been doing it for sometime. I guess that they could have slipped up though. I feel as if I was handed a mess with this pond. It is really cold tonight 17 degrees. It is supposed to warm up possibly next weekend 8 days away. If it does I will go down and try to catch one of the little snots and take a photo.
