5-15" We have smaller to very large goldfish.

Considered cold water fish, goldfish can also be kept in heated aquariums. The optimum temperature for fancy goldfish is 68° to 74° F, while comets and shubunkins should be kept between 60° and 70°F.  pH is not critical, but ideally should be between 7.0 and 8.4. Rapid changes in temperature or water chemistry can be harmful, if not fatal to goldfish. A tablespoon of aquarium or sea salt per 5 gallons can also be used to help keep goldfish in good health. Maintain good filtration and change 10% of the water weekly or 25% every 2 weeks using an Aqueon Aquarium Water Changer or Siphon Vacuum Gravel Cleaner. Don’t forget to treat tap water with Aqueon Water Conditioner before refilling your aquarium!


Goldfish should never be kept in bowls, small aquariums or any unfiltered container! In addition to having relatively high oxygen demands, they grow to be quite large and generate a significant amount of waste, which can be harmful if allowed to accumulate. Common goldfish, comets and shubunkins make excellent outdoor pond fish and are known to survive relatively cold winters. Fancy goldfish, such as orandas, ryukins, moors and others, can also be kept in outdoor ponds, but are more vulnerable to predators and must be brought in during winter in harsh climates. In aquariums, adult common goldfish, comets and shubunkins should have at least 20 gallons of water per fish, while adult fancy goldfish should have at least 10 gallons per adult fish. The filter should be slightly over-sized to accommodate high waste production and additional aeration is recommended when goldfish are kept at warmer temperatures. Larger goldfish will eat many types of live plants, with the possible exception of Cryptocorynes, Java fern and Anubias, although they may uproot these, too. Avoid decorations with sharp edges and abrasive rocks such as lava and tufa, which may tear delicate fins as well as eye sacs on bubble eyes, celestial eyes, moors and telescopes. Goldfish like to forage in the substrate, so avoid jagged or crushed glass gravel.  Provide adequate water flow but avoid strong currents. 


Goldfish are omnivores, feeding largely on crustaceans, insects and plant matter in the wild. A combination of Aqueon Goldfish Flakes, Goldfish Granules and Goldfish Color Granules will provide a high-quality diet. Frozen and live foods, including hornwort plant, can also be given as treats. Goldfish are naturally bottom feeders and may gulp air when feeding at the surface, causing them to lose equilibrium and float upside down. To avoid this, soak flake foods briefly before feeding and avoid the use of floating pellets. For best results, rotate your fishes’ food daily and feed only what they can consume in 2 to 3 minutes, once or twice a day.
