If you mean like what breed of goldfish you have then that should be fairly easy. I determined what kind I had by looking at his markings and going on wikipedia. If you go to Wikipedia.com and type goldfish in your search bar then scroll down there will be pictures of goldfish with the breed next to them. It is fairly easy and that's how I found out what my goldfish were.
