Commercial goldfish food -- available as flakes, pellets and granules -- contain all the nutrients goldfish need, and should form the major part of their diets. Overfeeding goldfish allows uneaten food to decay and contaminate aquarium water. Goldfish feces is another contaminant.
You should feed your goldfish two or three times per day, but only in very small amounts at a time. Slowly add tiny pinches of food to your tank, for about one minute, never adding more than your goldfish can eat in this time. If you leave food in your tank after feeding then it will get stuck in your filter and rot, which will pollute your water.
