Dave, thanks for the confirmation, but my real question was how did I get them and why are they so big so fast. Before the pond was in place there was only a small creek no more than three inches deep. I guess the guy got the fish from had less than perfect quality control? Anyway, from what I read, they are great eating and they are fun to catch! Do I need to be concerned with the balance in my pond? Will they cross breed with the other BG I put in the pond? Will they take over? Ect.
Again, thanks for the help.
