online comparison image:
The strange thing is that the top picture fish in my pond has scales that are light alternating with dark. The bottom fish seems to have a dark band all the way around the scale with a clear center like a diamond tile pattern.
The spotfin in the bottom picture has a blue band of color behind the gill cover, mine does not seem to have that.
