Ethoxyquin in Omega One dangerous?

[HKfshkpr1]

I am cosidering adding Omega One Super Color flakes to help with fish color. However, I read that the presevative Ethoxyquin in it could be poisonous to fish. They list salmon as an ingredient but does not specify wild caught, and farm raised ones are likely fed with food containing Ethoxyquin too.

I have a Spirulina flake that contains this stuff already. What do you guys think?

Most here will suggest not using flake food at all but consider using frozen or live foods, flakes lack proper nutrition for your fish and will increase phosphates in your tank. This link may help you make a decision on what's best for your fish
