I am sure you guys are right. Maybe I am getting too wrapped up in the color instead of their body shape. I saw where a fish's color was largely influenced by the water color. Maybe this explains why the fish in picture #3 are so different. Maybe one was a fish that has spent its entire life in my pond and the other one is one of my recent additions. That being said, I still think that there is a difference because of the different shaped forehead and mouth.
