    Ocean Nutrition dry flake food USED to be the best you could get. The ingredients list USED to start with whole salmon fillets and was followed up a huge list of quality ingredients. Unfortunately, it has now become an EXTREMELY cheap product. The first two ingredients are now "Dried Fish Solubles", followed up by "Wheat flour". Most retailers are listing the WRONG ingredients list. The best flake fish food on the market has now become one of the worst.

    Formula One

    My fish enjoy the Formula One product. I have a Bluefin Damselfish who is particularly finnicky. He seems to like the Formula One product, however.

    a staple food

    ive been using all these flakes for 8 years. Im convinced all the ocean nutrition flakes are the same mix, except for different dye color, but it doesnt matter as all my fish devour them all. therefore, when they are on sale I buy the largest size of all of them and mix them up. that usually lasts me a whole year. i feed flakes once per day with an autofeeder.
