Goldfish need a different diet than tropical fish. Although they can consume some tropical fish food, this should not serve as their main source of sustenance.
Goldfish require food with both moderate protein levels and high fiber. Tropical fish food usually contains higher protein concentrations with fewer fibrous ingredients, as it tends to float more freely causing over-inflated swim bladder issues in goldfish.

Protein
Goldfish require an adequate protein intake in their diet; unfortunately, tropical fish food typically only offers half as much. Furthermore, its floating formula causes it to float on top of the water surface, potentially contributing to swim bladder issues in goldfish.
Cobalt BLUE flake food, designed specifically for cold-water fish like goldfish, features probiotics for optimal digestive health and vibrant color enhancement, sinks to the bottom of their tanks. This formula features probiotics for vibrant color enhancement and healthy digestion – an example being Cobalt BLUE’s Cobalt Blue flake food with probiotics to maintain vibrant colors while supporting optimal digestive health and vibrant pigments.
Feed your goldfish tropical fish flakes from time to time, but opt for foods specifically made for them in order to prevent nutritional deficiencies and ensure maximum comfort while in captivity.
Carbohydrates
Goldfish are omnivores in their natural environments, eating a wide range of foods such as plants, algae, insect larvae, zooplankton, tadpoles and small crustaceans. Such sources contain nutrients rich foods should be included as part of a goldfish’s diet rather than as its main staple food source.
Tropical fish flake foods tend to focus more heavily on protein than essential fiber for their wellbeing, which could result in health issues like skin diseases.
An excellent alternative to feeding your goldfish flakes is providing it with live food such as brine shrimp, bloodworms, krill or squid that is both high in nutrients and promotes the development of healthy gut bacteria.
Fats
Goldfish can eat tropical fish flakes safely, but to ensure optimal health it is best to feed them specifically designed goldfish food such as flakes or pellets available from pet stores. Pellets tend to rot less in your tank and pollute its surroundings than their tropical fish counterparts.
Flakes are typically composed of algae and fish meal with added vitamins and minerals. Wild goldfish feed on aquatic vegetation, insects and smaller fish for protein and fat content; tropical fish food contains more protein but lacks fiber to provide proper digestion for goldfish.
Fiber
Goldfish require a diet rich in proteins, fats and carbohydrates. Their wild counterparts would have consumed plants, algae, insects and crustaceans; therefore they should receive high-quality dry pellets and flakes along with fresh or frozen vegetables and live foods like brine shrimp and bloodworms as part of their regular meal plan.
Goldfish will become sick and die quickly if fed food that does not meet their dietary needs, such as tropical fish flakes as their main food source. Instead, opt for higher quality prepared foods such as spirulina flakes and Hikari algae wafers which provide balanced protein/vegetable combinations while being packed full of essential vitamins and minerals.
Vitamins
Feeding goldfish tropical flakes should only be done occasionally as these foods do not provide them with all the required nutrition. A dedicated goldfish food product would be more appropriate, helping promote both healthy growth and beautiful color enhancement for your goldfish.
Wild crucian carp ancestors would likely have fed on algae, plants, insects and crustaceans – an extremely difficult diet to match with commercially produced flake foods or pellets. These special foods have been tailored specifically for goldfish needs with probiotics designed to aid digestion as well as color enhancers such as spirulina and astaxanthin for natural-looking glow. Plus these flakes are easier to digest without leaching colour into the water!
Minerals
Goldfish are omnivorous creatures, so while tropical fish food will satisfy their nutritional requirements, it may not be optimal. Tropical (warm water) fish food contains more protein than what would be ideal for goldfish diet.
Goldfish in their natural environment consume algae, plants, insects, shrimp and other forms of protein; an ideal diet should include these elements while adding flake food supplements as supplements only as needed.
Ideally, when feeding goldfish flakes to them, try to rotate their diet each week so as to maintain a healthy digestive system and avoid depletion of nutrients in the aquarium. This will prevent depletion from taking place as quickly.
