Fish Food Ratings by OscarFish.com

Note: The following was compiled from articles published on OscarFish.com which is no longer live. This is being republished here so that the information isn't lost. Food formulations may have changed since these ratings were originally published. These ratings are based on ingredient analysis and not actual use. There's a related article I re-published that describes what fish food ingredients are good and bad.

6 Star Foods

It's unclear which specific food received a 6-star rating. All that the site mentioned was Northfin Fish Foods. Northfin and NLS were considered to be very close with the only difference described below:

Very little, if anything, separates Northfin and NLS. NLS may even be a better product due to the healthful benefits of Chlorella Algae and Ulva Seaweed. The reason Northfin has received a 6 star rating and NLS remains in the 5 star category (5.5 stars) is that I have been able to receive an “Ethoxyquin Free” statement from Northfin, to include absence of Ethoxyquin in pre-manufacture meals. I have not been able to receive an Ethoxyquin free statement from NLS. Site rules in ingredient ratings is that to achieve a “6 star” rating, the manufacture must identify an Ethoxyquin free food.
