Yes, goldfish can eat tropical fish food, though pellets are preferred over flakes to prevent air accumulation that could potentially lead to swim bladder disorders in round-bodied fish.
Pellets sink, making them easier for mid/bottom water feeders such as goldfish to ingestion. Goldfish should be fed multiple times daily with varied foods.

Protein
Goldfish require a diet high in proteins for maintaining healthy body tissues. Protein also acts to bind minerals, vitamins, and other vital nutrients together for maximum absorption by their bodies.
Most commercial tropical fish flakes contain lower protein levels than required by goldfish, and typically include an array of additives and preservatives.
Goldfish should receive some live food such as brine shrimps, bloodworms and daphnia as part of their diet. You can either cultivate these yourself at home, or purchase frozen packs at your local pet shop.
Another option for goldfish feedings is gel food, consisting of powder that must be mixed with water to form a thick gel-like consistency. Although popular among goldfish, too much gel food could lead to issues of digestion and buoyancy (as the fish stuffs it down it absorbs moisture that causes buoyancy problems). Freeze-dried foods, like Krill can also be added into their diet to increase carotene levels for enhanced pigmentation of red pigment growth and vibrant colour.
Carbohydrate
Goldfish require a balanced diet composed of both proteins and carbohydrates for proper growth. High-protein food with too many fillers or additives that cause bloating should be avoided as much as possible; feed your goldfish twice a day only as much as they can consume within minutes; overfeeding can lead to swim bladder disease or other health issues.
Pet stores carry freeze-dried foods that are easier for these fish to digest, including brine shrimp, blood worms and tubifex worms – these food options often feature squid or krill to boost carotene levels in these fish’s bodies and promote contrasted colorations. They’re an excellent alternative to tropical fish flakes; perfect for emergencies as well. Goldfish have an estimated two week lifespan without food but starvation may cause serious health complications.
Vitamins
Goldfish feed on various aquatic organisms in their natural environment, including plants, insects and fish eggs. When kept captive in an aquarium setting, you can provide your goldfish with tropical fish flakes and dry pellets designed to meet their nutritional needs.
Flake and pellet food should contain low levels of protein while providing your goldfish with plenty of plant-based nutrition, and should have low raw ash content to reduce water pollution. In addition, there should be an array of vitamins and minerals in its ingredients in order to promote health in your goldfish.
Tropical fish flakes contain high protein levels but lack fiber. Although tropical fish flakes may provide temporary solutions if your goldfish food runs out, they should not become your pet’s staple diet.
Minerals
Goldfish have delicate digestive tracts and require plenty of nutrition at each meal. Aim to provide them with a balance of proteins, carbohydrates and minerals – including freeze-dried food like brine shrimp, blood worms or tubifex worms as well as pellets containing ingredients such as wheat germ, dehulled soybean meal, feeding oatmeal corn gluten fish meal ground brown rice potatoes spinach kale dried krill dried shrimp algae D-Lysine Monohydrochloride salt lecithin lecithin plus added vitamins and minerals.
If using flakes or pellets, ensure they sink rather than float to prevent goldfish from inhaling too much air at the surface and leading to swim bladder issues. A newer type of fish food on the market are gel foods made by mixing powdered food with water into a soft gel-like consistency for easier consumption by goldfish.
Fat
Goldfish require a diet rich in proteins with very limited fats and carbohydrates; too much of either could lead to weight gain and health complications in their lives.
Fancy goldfish have more compacted bodies which can strain their digestive systems. Therefore, live earthworms should not be fed as these may block up internal organs; dried bloodworms offer an alternative source of protein.
Tropical fish food may not be ideal for goldfish as it often contains too much algae, floating foods and vitamins for them. They should therefore consume dedicated goldfish food with occasional algae wafers, pellets or vegetables to ensure they remain well fed and happy.
