The supplements contain what we believe are the basic vitamins and fats needed to sustain fish long-term health. The elements are added through trace element additives and water changes. So the nutrients that are: fats, vitamins, elements are in supplements or additives so far as we've analyzed. I think some vitamins, like Vita-Chem that derives its ingredients from sea organisms is a good way to include even some things we may be unaware. Combined with the basic good food practices, we have reason to believe we have addressed what needs to be addressed from observing captive fishes living beyond 20 years in good health.
P.S. I enjoy a respectful good dialoge and exchange of perspectives.
