Goldfish thrive when fed a wide range of foods, particularly those rich in protein from whole fish and meat sources, along with fiber, fats and vitamins for good health and vibrant coloration.
Pellet foods tend to be preferable for goldfish because of their slow sinking action, preventing air-gulping which can lead to digestive problems in fish. When selecting food pellets for your goldfish tank, choose ones containing protein, probiotics, and color enhancers like spirulina for optimal performance.

Pellets
Pellets are one of the most widely consumed food options for goldfish, as they’re designed to be easily digested. A high quality pellet food will contain more proteins and less carbs than its flake counterpart, meaning you can feed smaller portions throughout the day without risking an accumulation of uneaten food in their tank.
Northfin Goldfish Formula is an example of an exceptional, slow-sinking pellet specifically tailored for goldfish. It contains organic kelp, whole arctic krill meal and spirulina; plus garlic and vitamin C to promote growth while decreasing ammonia levels.
Flakes
Goldfish feed on a range of foods, from pellets to flakes. No matter their weight or shape, the ideal goldfish food offers an adequate balance between proteins, fats, and carbohydrates for their wellbeing.
Contrary to some flakes, this one has been designed specifically for goldfish and contains an optimal blend of nutrients that minimize waste that could pollute water bodies while providing a probiotic for enhanced immune protection.
Fancy goldfish require diets rich in carotenoids to show off their stunning hues, and these flakes made of pepper meal, chlorella algae and krill meal provide your fish with natural color-enhancing pigments while providing essential protein for growth and muscle development. It’s also great for fish with sensitive digestive systems.
Gel Food
Goldfish require the appropriate food in order to live a long and healthy life. Low quality foods often contain fillers that cause constipation, bloat and swim bladder issues in fish, as well as vitamins that don’t actually benefit their wellbeing; any time vitamins appear in abundance on an ingredients list this should be a warning sign!
The top gel foods for goldfish are soft and easy to digest.

Fruits
Add variety to your goldfish food with fruit! Fruit is a rich source of essential nutrients, keeping your fish happy and healthy. However, be careful with their intake as too much fruit may make digesting difficult for them.
Goldfish food comes in the form of flakes, pellets, gel or even live food.

Treats
Goldfish have many alternative feeding methods besides just flake food and pellets; you could try sinking pellets, gel foods, thawed frozen food or even leafy greens like dandelion greens as food options.
