Goldfish may occasionally benefit from being fed tropical fish flakes, but these should never become their main food source. Each species of fish requires specific vitamins that can only come from eating certain kinds of food sources.
An examination of the ingredients list on tropical fish flakes and goldfish flakes quickly reveals their distinctive contents.

Protein
Goldfish in their natural environment are opportunistic omnivores that eat plants, algae, insects and crustaceans. To survive they require a diet rich in proteins but low in carbohydrates; otherwise they will become obese and eventually die an agonising death.
Tropical fish food contains high concentrations of protein and fat to closely mimic their natural diet, so feeding it to goldfish on an ongoing basis could prove disastrous.
Frozen foods like brine shrimp, daphnia and tubifex worms are widely available at pet stores, providing goldfish with an excellent source of protein. When feeding frozen foods as staples they will quickly be broken down by bacteria in the tank resulting in bacterial blooms and dirty tanks.
Vegetables
Many goldfish food brands include vegetables in their formulas to enhance the color of your goldfish and ensure its health and vitality. Carrots and peas in particular contain carotenoids which help your fish maintain vibrant hues.
Goldfish food with a high concentration of vegetable matter is ideal for tropical fish as it will not increase ammonia levels in your aquarium, since uneaten food produces nitrate that may harm or kill fish.
Your goldfish can also benefit from eating small portions of fresh vegetables like green peas, zucchini and cucumber slices blanched for just a few seconds to soften and make eating them easier for their fish. These veggies provide a healthy alternative to pellets or flakes.
Meat
Goldfish food should provide their fish with protein from various sources. Krill is one such protein source, rich in Omega-3 fatty acids and other essential fatty acids as well as delicious for them!
If you prefer something simpler, why not give freeze-dried food for tropical fish a try? These tasty meals often consist of inverts such as krill mixed with plant material like spirulina.
Live snacks may also provide your goldfish with variety in their diet, such as daphnia, brine shrimp or bloodworms. Simply be sure to thaw out these items prior to feeding them to them so they’re easy for your goldfish to digest. These should only make up a small part of their meal plan as too often feedings may lead to digestive issues in fish; they should instead serve as an easy way to add variety. For the sake of safety and long term fish tank health be sure to purchase from reliable providers so your tank stays healthy over time.
Shrimp
Goldfish live in aquatic environments where their diet consists of algae, plants, insects, shrimp and other animal matter. You can replicate this diet using high quality flake food.
Lower-quality manufactured foods often contain fillers like brown rice, oatmeal and wheat gluten that would not normally feature in their natural habitat. Furthermore, such food often includes table sugars and other sources of carbohydrates which could potentially cause bloating or blockage issues for goldfish.
Another option for feeding goldfish is feeding them gel food that comes in powder form and needs to be mixed with water to create a jelly-like consistency. These types of foods are becoming increasingly popular and often come in an assortment of colours.
Feed your goldfish only occasionally with gel food to avoid digestion problems. Some gel foods contain live brine shrimp as a protein source, making this food particularly helpful for their digestive systems. However, only use live brine shrimp if you are experienced at cultivating them as these may contain bacteria that could potentially harm their health.
