Yes, goldfish can eat tropical fish food, though this is not always recommended as each individual fish has different dietary needs and overfeeding on this tropical food may lead to their illness.
Tropical fish food contains high concentrations of protein but lacks essential fiber, so it’s crucial that you read the nutritional analysis on its label before purchasing tropical fish food.

Dietary Needs
Goldfish and tropical fish species each require specific diets for optimal health, and providing your goldfish flakes as a staple food may lead to health problems in time.
Your goldfish should receive all the protein and carbohydrates it needs from high quality flake or pellet food, although you may supplement their diet with foods such as peas (be sure to remove their skins first) and blanched vegetables, along with live or frozen bloodworms, mosquito larvae, daphnia or brine shrimp for additional nutrition.
Cold water fish have slower metabolisms than tropical varieties and require a higher protein and fat content in their diets to thrive. Flakes, pellets and freeze-dried preparations should provide optimal conditions.
Ingredients
Tropical fish food often contains high protein levels that are difficult for goldfish to digest, leading to constipation, illness and ultimately even death for their aquatic friends. Instead, owners should provide their fish with foods tailored specifically to meet its dietary needs such as high-quality dried foods, aquatic meaty treats and plant foods like alfalfa, spirulina and kelp.
Food specifically tailored for goldfish should contain supplements like beetroot to increase color enhancement. Although tropical fish food should never be fed directly to goldfish, in an emergency it may be fed occasionally in small quantities if none other alternatives exist. In the long term however, feeding your goldfish pellets, flakes or freeze-dried preparations would likely be more beneficial for its wellbeing.
Protein
Goldfish are opportunistic omnivores in their wild environment and need a diet rich in both plant and animal-derived proteins for proper survival. Unfortunately, tropical fish food tends to focus exclusively on animal protein sources while lacking vital plant based nutrients that goldfish require for health and development.
Tropic fish food typically contains too much protein for goldfish to digest properly, leading to bloating and swim bladder disease.
Feeding your tetras goldfish flakes occasionally won’t harm them, but it might not meet their individual dietary needs. Instead, opt for feed specifically designed to meet their nutritive requirements; one with plenty of vitamins and minerals but low amounts of protein; as well as ingredients designed to provide healthful and balanced nutrition.
Carbohydrates
Tropical goldfish food often includes many starchy carbohydrates derived from brown rice, oatmeal, wheat gluten and dried yeast – grains which do not belong in their natural diet and which may lead to digestive issues in fish. They may even contain an enzyme that destroys vitamin B1 from within their system.
Though technically possible to mix goldfish and tropical fish in one tank, it is not advised. Goldfish have very different metabolic rates from their tropical counterparts and produce large volumes of organic waste, often leading to ammonia or nitrate spikes that threaten other fish lives. Furthermore, most tropical fish flakes lack essential fiber which goldfish require for healthful living.
Fat
A typical tropical fish food contains high amounts of fat from sources such as fish and fish derivatives, cereals, oils and fats, vegetables (including 0.8% beetroot), extracts from vegetable origins, mineral sources, fruit sources and yeasts. Common analytical constituents are proteins, crude fibres, fats, inorganic material and ash.
Goldfish require a diet rich in proteins in order to maximize growth and maintain body condition. As bottom feeders, goldfish typically scavenge food from the substrate in their natural habitat; alternatively they may be fed either flake food or sinking pellets for feeding purposes.
While goldfish could consume tropical fish flakes as food temporarily, doing so can have long-term negative consequences that include weight loss and health concerns.
