Fish Herder
I was on fosterandsmithaquatics.com looking at fish food. Noticed their brand claimed "Contains no artificial colors or preservatives (many fish foods use ethoxyquin, which has been shown to cause mortality in fish)." So I check my container of TetraMin and Ethoxyquin is listed in the ingredients. So I start doing some research and everything I have read basically says Ethoxyquin is used in a lot of pet foods and it's toxic to every pet especially fish. So I dig out my container of New Life Spectrum out of the back of the fridge and check the label, it doesn't contain Ethoxyquin. I had put it in cold storage because my fish at the time would not eat it. So I try some today and they have changed their minds and now like it. The TetraMin went in the trash can. Maybe this is why I was losing fish in water with 0.001 NH3 and a good maintenance routine? We shall see.
