The Sarasa Comet is a type of single-tailed goldfish, and belongs to the family "Cyprinidae." Also called the Comet-tail Goldfish, they are originally native to China. Sarasa Comets grow up to 35 cm (14 inches), prefer low lighting and are omnivorous. This tough, hardy fish is typically shocking red in colour, with some white patches, although some are completely orange to red in colour.

  1. 1

    Choose a large tank -- at least 90 litres (20 gallons) -- that can hold up to three fish and provides the maximum amount of surface area, to maximise 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. Buy a cover for the tank as well, to minimise evaporation.

  2. 2

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

  3. 3

    Use the aquarium test kits to test the water temperature, acidity and hardness. The ideal tank conditions are water temperatures of 18.3 to 22.2 degrees C (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 18.3 degrees C (65 degrees F). In this case, you will not need an aquarium heater.

  4. 4

    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.

  5. 5

    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 set-up. Avoid live plants, as fish will nibble on them.

  6. 6

    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, corgettes and lettuce.

  7. 7

    Provide your Sarasa Comet goldfish with some tankmates. Aside from fellow Sarasa Comets, other alternatives include Koi, fancy goldfish and common goldfish.

Tips and warnings

  • Sarasa Comets are one of the hardiest varieties of goldfish that do just as well in an indoor cool-water aquarium or an outdoor pond.
  • Keep young Sarasa Comet goldfish in an unfiltered bowl 4.5 litres (1 gallon) or larger in capacity. Frequent cleaning of this fish bowl and water changes are necessary.
