Definitely a mirror carp I have caught them before and I know others who have caught them not knowing they were a mirror carp and had made the comment that they caught a very sickly looking carp that was losing all of it’s scales when in fact it was a healthy mirror carp.
In Albert Lea, as a kids growing up we called them Indian Carp.
The Orange (Goldfish) or Orange & White or Orange, White & Black ones they now call Koy we called Orange Carp. We slaughtered them by the Hundreds or Thousands every Spring!
