I actually bought some Georgia Giants two years ago along with other fish I put in our then new pond and quite honestly, two years later--they are doing very, very well. They are bigger and more aggressive and have surpassed the bluegill in size. I have read alot about the F1 and F2 and stuff like that so I know down-the-road I may have a correction to do in population. But in the interim, our pond is SO enjoyable and we are not disappointed in the Georgia Giants by far. \:\)
