You can see my old 22" big black arow. You can see the body is not as deep and the seem to have a less pronounced face. Under the same light my silvers had different colors. as well. Their scales will still have a very slight tint of blueish hue to them as well. the fins will still have blue so that is the easiest way to tell. Silvers fins are eiather pinkish or drab gray
