Instructions

    • 1

      Choose a large tank (at least 20 gallons) that can hold up to three fish and provides the maximum amount of surface area, to maximize the oxygen supply. For example, when choosing between two tanks of the same water volume, purchase an elongated tank rather than one that is deep. Purchase a cover for the tank as well, to minimize evaporation.

      Clean your tank after you purchase it. Fill it up partially with hot water, then scrub it with a dishtowel. Empty and dry the tank, then fill it with room-temperature water. Let it sit for 24 hours before adding the fish.

      Use the aquarium test kits to test the water temperature, acidity and hardness. The ideal tank conditions are water temperatures of 65 to 72 degrees F, pH levels from 6.5 to 7.5 and a dH of 5 to 15. Test for these conditions every time you change the aquarium water.Ensure that your tank is in a spot where the temperature of the water will not drop below 65 degrees. In this case, you will not need an aquarium heater.

      Install your tank filter. An outside power filter is recommended. Aquarists also recommend that you make weekly water changes of about 1/4 to 1/3 to keep Sarasa Comet goldfish healthy.

      Wash your gravel in hot water, then add it to the tank. Add the aquarium decorations. Small rock and/or driftwood provide a hiding place while creating an attractive tank setup. Avoid live plants, as fish will nibble on them.

      Sarasa Comet goldfish are omnivorous. Provide a daily diet of high-quality flakes and pellets, along with regular treats of brine shrimp, blood worms and/or tubifex worms. You can also feed them peas, zucchini and lettuce.
