I got one question, and believe me I am not as hard core about what food I use as some are I just want the best for my fish. I do feed variety but mostly for the enjoyment I get from it. I have been wanting to try NLS etc. but I have been a big vitamin, mineral etc supplement user myself in my own diet. Now all this news that the synthetic vitamins could do more harm then good. Cant this apply to the pellets that have them added after the cooking process?? I have almost completely stopped using them in my own diet and have just changed my diet to attain these vitamins etc in their natural state. Are the replacement vitamins etc synthetic man made?
