Proper Goldfish Feeding

Proper Goldfish Feeding

By Carl Strohmeyer

A quality Koi and goldfish food starts with quality aquatic based ingredients. Fish derive their energy from fats, not carbohydrates (although cereal is needed as roughage). also the ammino acids that make up proteins should be ones that can be easily metabolized by fish. Soy proteins and feather meal that are used by many foods are of poor quality. An analogy I used in another blog to compare ammino acid (protein) quality is this: You can achieve the protein analysis of many pet foods with a pair of leather shoes, yet leather shoes are for the most part, made up of undigestable proteins that will eventually lead to renal (kidney) failure in fish.

It also should be pointed out that no one food should be fed alone (including Sanyu). A balanced diet for goldfish should also include Spirulina Flakes and Brine or Mysis shrimp (which have a natural laxative for goldfish). Frequency of feeding is also important, think of goldfish as under water horses, they are regularly grazing, unlike say a lion. The point is that goldfish have long digestive tracts, not unlike horses, and if not kept full, they can develop gas (that is also why the brine shrimp and spirulina are important). Try and feed your goldfish at least two or more times a day (if more often, feed less per feeding).

Sanyu Vital is a complete diet to provide all necessary nutrition for goldfish and koi. This food is formulated to meet the diet requirement for goldfish and koi. The raw material used is selected from vegetable based, high carbohydrates and less protein ingredients are easily digested. Feeding this food will result a rapid colour enhancement.With various vitamins and minerals added ensure the fish stay healthy and vital. Although this food contains soya meals (a poor source of protein in fish), it derives the majority of it’s proteins from quality sources such as spirulina vegetable proteins and fish meal.


Vegetable protein extract, fish meal, soya meals, rice bran, wheat flour, corn meal, carotenoid, lecithin, vegetable oil, vitamin A, C, E and important minerals and trace elements


*A quality food (another is Spirulina 20 Fish Food Flake),

*Changing water (20%) once per week,

*Keeping a ph of 7.2- 7.6,

*Proper mineralization and electrolytes, using products such as Wonder Shells.

*Proper filration (including germacidal)

*And proper tank size (one average adult goldfish per 4-8 gallons, depending on filtration)

Sanyu Tropical fish and cichlid food is similar in quality, but with a higher concentration of aquatic based proteins (such as shrimp meal) and less vegetable based ingredients.

TropicalFish Food Ingredients:

Fish meal, shrimp meal, dried yeast, wheat flour, corn meal, fish oil, carotenoid, inositol, vitamin A,C,D, calcium iodate, iodine, magnesium and other elements. Analysis: Protein 37%, Fat 3%, Fibre 4%, Moisture 10%
