Yes copper is bad for shrimp!
I don't know about that food but I had made a mistake when I was in a hurry and bought something called shrimp pellets. It had copper in it so I didn't use it and realized it was made of shrimp not for shrimp!
Hope somebody else can help you about the food, I just know copper si not good for shrimp!
Good luck!
Cindy
