Here's an article from our sister site which might help ease your mind. Note Byron's response.
Thank you! That's good to know about the bettas! Very interesting about Byron's response. I only discovered the copper in the food thing because I went to the breeders page I got the shrimp from looking for something else and it has a bright red copper warning on it which I honestly didn't read when I was ordering them because I know copper is toxic, this time I read it and it was all about copper in fish foods being toxic and what it would be called in the ingredient list. I was like WAT lol. Both of my shrimp deaths happened shortly after I fed the copper food to my betta. Also very interesting I ordered Sakura cherry shrimp and they threw a couple common reds in, from my understanding the common reds are supposed to be much hardier but both of my deaths were common reds, not any of the Sakura. I didn't have any issue finding betta pellets, regular fish flakes or algae pellets that didn't contain copper, looks like most of the omega line doesn't contain copper. I think new life spectrum betta pellets didn't either. So I figured it was more just lower quality foods that contain it?
