Quite incorrect actually...I have been using it for years and my oscars thrive well and love it.Really?!! Have you read all the aweful stuff they put in Hikari foods?? Food coloring, preservatives, starch... Seriously, if you want your fish to be happier and healthier, I would recommend Omega One. They use only fresh seafood, and have no preservatives or food colorings! It also contains way less starch.
