Goldfish require a diet high in proteins for healthy development. Their source must come directly from food rather than waste or decaying plant matter or algae found in their tank environment.
Goldies have limited stomachs and must be fed multiple small doses of flake or pellet food throughout the day to promote optimal development. Only feed them what they can consume within one minute, and remove any uneaten food promptly.

Protein
As with other fish species, goldfish require protein for proper development and care. Because they’re omnivorous fish, their protein source comes from both plant and animal sources – blood worms, brine shrimp, and mosquito larvae are readily accepted by most goldfish and should be fed periodically as extra protein source; frozen foods like these may even be purchased at pet and aquarium stores for convenience.
Feed your fish only what they can consume within two minutes when feeding flakes, pellets or gel foods. Overfeeding can cause digestive issues that lead to buoyancy problems and diseases that lead to death; to avoid this happening again quickly remove any uneaten food after two minutes and give only as much food as can be digested in two minutes; occasionally offer goldfish vegetables such as peas (without skin), zucchini and lettuce that have been blanched for just a few seconds to help make digestion easier.
Carbohydrates
As a rule, general fish foods contain higher levels of protein and fewer carbohydrates than goldfish require. Instead, opt for specially tailored goldfish food or include plant matter into their diet, such as boiled kale, collard greens, spinach or mustard greens as excellent sources of vitamins that will ensure their wellbeing and fitness.
Goldfish need fats from fish oils found in salmon and tuna to sustain healthy growth and avoid nutritional deficiencies. Goldfish also require some carbohydrates; however, excess amounts should not exceed 10% as these can accumulate in the liver and create problems for health. Therefore, frequent feeding will promote optimal growth while eliminating potential nutritional deficiency issues.
Fat
Many people mistakenly think goldfish don’t require fat to survive, yet fat plays an integral part of their diet and helps absorb protein.
When selecting food for goldfish, look for options with a higher ratio of fat to protein than carbohydrates. Carbohydrates cannot be fully processed by their bodies and too many can lead to liver diseases.
Goldfish food comes in the form of both floating and sinking pellets, the former floating on the surface while sinking ones settle at the bottom of the tank. Although floating foods tend to be easier for goldfish to digest, they still may overfeed themselves and leave behind uneaten food behind.
Overfeeding can lead to numerous issues for fish, such as stress, bacterial growth and decaying food that releases harmful toxins into the water.
Vitamins
Goldfish do not produce their own vitamins; therefore they must obtain them through food sources such as fish flakes. Their diet must include A, D and K vitamins along with folic acid for proper growth. Frozen or live treats may add additional variety to their diet.
Some goldfish owners supplement their aquatic pets’ diets by feeding them vegetables and fruit as supplements. Goldfish fish like to nibble on peas (without skins), zucchini and leafy green vegetables which can easily be added into their regular food regimen. Blanching these veggies before offering is recommended in order to facilitate easier consumption; too many extra foods could potentially cause digestive blockage or cause blockages to form within their digestive systems.
Minerals
Goldfish require a diet rich in minerals. You can provide them with specially prepared flakes and pellets as well as plant matter or cooked vegetables to meet this need. Doing this should give them all of their essential nutrition needs.
However, it is essential not to overfeed. It is best to only feed your fish as much as they can consume within minutes; this helps avoid waste in your aquarium water and digestion issues.
Ideal, goldfish should be fed twice or three times daily to prevent issues like swim bladder problems, food impaction and fatty liver. Fancy types are especially prone to these issues due to their longer torpedo-shaped bodies that make them susceptible.
