Goldfish in ponds require high protein diets. They consume infusoria, live food like brine shrimp and plant-based commercial foods like goldfish flakes or pellets.
Dietary needs of fish vary with water temperature. Overfeeding strains dissolved oxygen levels and excess fish waste can result in toxic bacteria blooms.

Feeding Frequency
Goldfish in ponds should be fed regularly depending on the temperature of their environment, with warmer waters needing to be fed more often and at 2-4 times a day with high quality food like Aquascape Premium Stable Fish Food Pellets.
Goldfish in their natural environment consume aquatic plants as well as the meaty remains of amphibians, insects and tadpoles – up to 30% of their bodyweight per day!
As spring and summer progress, it is wise to provide fish with additional food supplements in order to encourage them to bulk up for winter. Be mindful not to feed more than they can consume within several minutes as any uneaten food may sink to the bottom of the pond, breaking down and creating harmful bacteria waste that pollutes water parameters. Furthermore, overfeeding can cause stress for fish while increasing ammonia and nitrate levels – it would be wise for any pond’s filter system to assist with disposing of any waste food produced.
Temperature
Goldfish are energetic creatures that quickly consume any food added to the water, yet only consume what their bodies can process within minutes, so it is essential not to overfeed. Uneaten food will eventually sink to the bottom and decay, polluting your pond’s ecosystem and degrading water quality further. With an effective filter system in place, uneaten food may often be removed effectively to improve overall water quality.
As water temperatures decrease in fall ponds, fish such as koi and goldfish enter a hibernation-type state where they don’t require feedings for up to six months. Once temperatures consistently remain above 50 degrees again, you may resume feedings – initially offering wheat germ-based food because this can easily be digested by them; later when temperatures return closer to the norm you can switch back over to regular fish food products.
Supplements
Goldfish require a diet tailored specifically for them in order to remain at peak health, with seasonal and age-specific needs that must be fulfilled. There are many pond fish food products available which can supplement your goldfish’s natural diet and help ensure its wellbeing.
Tetra PondFood has been specially developed to meet the nutritional requirements of all sizes of koi and ornamental goldfish, providing your fish with everything they need for energy, longevity and overall health. It contains polychaete worms for increased palatability; pea protein to improve digestion; and marigolds as a natural source of carotenoids – providing your fish with ideal maintenance diet!
Another effective solution is feeding high-quality frozen food such as spirulina flakes or daphnia that contain high levels of DL-methionine for enhanced color enhancement in goldfish. You can purchase such treats at many pet or fish stores, providing only what the fish consume in two minutes and promptly taking action to remove uneaten food from your tank or pond.
Time of Day
Outdoor ponds often house goldfish which forage for food by feeding on aquatic plants and decomposing plant material found there, as well as any floating algae they come across.
Goldfish in an aquarium or pond need to be fed at least once daily, and ideally more often. Being omnivorous fish, they require a varied diet including prepared fish food (flakes and pellets) as well as green vegetables, algae, blood worms and spirulina as well as foods like mussels and shrimp for good health.
As metabolisms of goldfish and koi fish peak during the warmer summer months, higher protein food should be provided until autumn arrives when temperature begin to drop; then when temperatures cool further still, low protein wheat germ based food should be offered until winter approaches and metabolism slows. At this time, only feed them enough food that they will consume in 3-5 minutes to prevent pollution in your pond.
