ive read that a lot of people feed a varied diet. what does that mean, specifically? is it different foods in one day or different foods on different days? i have nls, omega 1 flakes, peas and zucchini. i usually just grab whatever and feed it in no certain pattern. i have 3 platys in one tank, 2 goldfish in another. should i be feeding the goldfish goldfish flakes? any suggestions on a feeding pattern? i am interested in what you feed and how you vary it. thanks
