I was doing some research comparing frozen foods versus dry foods. I thought that the frozen, being in the usual form that fish eat, would be more beneficial. I was surprised to find this is not necessarily the case.

Taking information from mongabay.com, regarding nutritional needs, I compared the nutritional value of frozen versus dry foods. The frozen foods did not even come close to supplying the nutritional needs. In fact, it appears that frozen foods should count as a supplement or occasional alternative to dry foods.

I found that the nutrients supplied in the frozen foods were either excessive or deficient. Why the disparity? I don't understand why normal, natural foods would be less beneficial than the dry versions, with the exception of additional vitamins and minerals. Any thoughts? Hve a look at the information below and see what you think.
