Hi, ive been wondering why bluegill or bass have different coloring, even when they are the same species. Ive been curious ever since i compare the coppernose in my pond to pics of other ppls coppernose. I think maybe what they eat is a factor but im no quit sure. If some one could elaborate on what deermines fish color it would be appreciated. P.s i googled to find out myself but found nothin!
