Gold Fish Pellets?

So I got this in a bundle from a facebook auction and I was wondering, can I use this?
I have no gold fish and do not intend on getting any (I would love a fancy one but 12-14 inches is too big for me!) I really don't want this to go to waste but can I feed it to my other fish? (I have guppies and tetras.) What concerns me is that it contains copper sulfate and I have shrimp but so does all my other food and my shrimp love it! To my knowledge I have only lost 3 out of 12. Soooooo I have no clue!

I wouldn't use it personally the ingredients are super sketchy... dehulled soybean meal and ground wheat? Why bother using it when you can get high quality food for a cheap price

 

The guppies and tetras, although pretty small, may pick at them and slowly eat the small pieces. My guppies and fry do this all the time.

For the shrimp, from my experience, shrimp needs some trace of cooper to survive. An unreasonable amount of copper certainly can kill shrimp, but this food should be safe. Just keep an eye on them. If a lot of them die at one time, stop using it. They should be fine though.

 

But from recent research, I have seen reviews that these pellets are pretty big, and should really only be fed to large koi. To be on the safe side, maybe just consider buying flakes or pellets small enough for the guppies and tetras.

 

A good fish food should have whole fish as the first ingredient imo, so I personally wouldn't use that. Omega one is usually my go to.

 

Thanks, after reading this I think I will just stick with my wardley!
