I agree with Cecil and Bruce. Aaron's fish looks exactly like the bgill X GS natural cross (at abt 6" long) that a neighbor has in his pond. As they get older they will develop subtile changes in body shape and coloration. However I cannot tell which of the parent fish was male and female. I will try to get a photo of one of my "local 6" hybrids" this weekend. So a photo comparison can be made. Note that is important to compare fish of similar size.
