What and how to feed your goldfish
Knowing what and how much to feed your goldfish is a key part in being a proper goldfish owner. Eating the wrong type, or wrong amount of food can be very bad for your fish. A mixture of specialized goldfish flake & granules or pellets are a good staple diet. Knowing how much to feed your goldfish depends on many factors such as, the size of the tank, for example you do not want to make the water dirty by overfeeding or feeding "goldfish flakes", The size and number of goldfish, for example big fish eat more and so do more fish. For an average common goldfish, the recommendation is only about a pinch of food twice a day, if you have over three fish then three to four times a day is recommended.
