Goldfish require a varied diet with plenty of fiber in order to thrive, as feeding one type of food over and over may lead to digestive problems and buoyancy issues.
Ideal goldfish food should consist of specialized goldfish flake and granules along with frozen earthworms and brine shrimp (or daphnia). Homemade vegetables may also be offered, provided that they can be cut or crushed small enough for your fish to swallow safely.

Freeze-Dried Food
Freeze-dried food can add variety and extend shelf life of existing foods. The freeze-drying process preserves nutritional values of fruits, vegetables, meats, grains and beverages while making them easy to store, transport and prepare.
Freeze-drying (also referred to as lyophilisation) involves freezing food products before subjecting them to heat at very low temperatures, which causes water molecules in frozen foods to instantly transform from their liquid state into gas without passing through liquid phase, thus drastically reducing water content of foods, making them significantly lighter in weight.
Freeze-dried foods make an excellent addition to outdoor recreation and emergency preparedness kits, whether camping or emergency preparedness. They can either be eaten directly as is, or rehydrated with water into nutritious snacks or meals – and many retain their original flavors and textures while closely matching the raw product in terms of nutrient density.
Live Food
Dried food should form the bulk of a fish’s diet; however, live food can help increase growth rate, coloration and overall health benefits while improving growth rate and coloration. Due to parasites and bacteria which could be harmful, live food should only form part of its diet.
Live food provides a natural diet that closely mirrors what fish would eat in their natural environments, making digestion simpler than with commercial feeds and helping reduce digestive problems.
Live food stimulates fishes’ natural hunting and feeding behaviors, providing mental and physical activity. However, it is essential to provide a varied diet with both dried and frozen food in order to prevent obesity or water quality issues related to overfeeding of live foods (such as daphnia or brine shrimp ). Live foods may carry parasites or disease organisms which could potentially infect other inhabitants in an aquarium environment.
Vegetables
Goldfish fish will enjoy snacking on fresh vegetables such as kale, spinach, carrots and sweet potatoes. You could also plant some lettuce leaves or Swiss chard in the aquarium gravel so they have something tasty to chew on!
Goldfish require a diet high in proteins for growth. Furthermore, they require various vitamins, minerals and amino acids for optimal health – an adequate fish food should provide all these essential elements while also offering an ammonia source to avoid stress on both their lives and those of the environment.
Hikari Goldfish Food is an excellent option, featuring premium whole fish meal, shrimp meal, wheat flour, spirulina algae and corn meal that are easily digestible by goldfish. Plus, Hikari includes natural immuno-stimulants and probiotics to aid digestion and immune defenses of goldfish as well as color enhancement in Koi and goldfish species alike with its use of DL-methionine for Lionhead pattern enhancement in fancy goldfish – it has proven very popular with top Koi breeders alike!
Treats
Goldfish require a varied diet as their digestive tracts are designed to accommodate constant grazing (much like horses). Without variety in their daily meals, goldfish could quickly become bored of eating one particular kind of food all day long.
Consider providing your goldfish with a mix of dry and freeze-dried food, as well as fresh or live vegetables, several times each week. You could plant lettuce or other veggies directly in their gravel beds or use a veggy clip to hold vegetables beneath the water’s surface for them.
Check the guaranteed analysis on your goldfish food to ensure it contains an appropriate mix of amino acids required by goldfish to thrive. Look out for high levels of DL-methionine as well as vegetable proteins from spinach, green peas and garlic as this will ensure they receive all of their required vitamins and nutrients – deficiency can lead to serious diseases in later years!
