Instructions

  1. Identify the Fantail Goldfish

    • 1

      Take into account its bright, variable coloration. This varies widely in different shades of reds, oranges, white and black, depending on the scale formation and pigmentation of each specimen.

    • 2

      Identify the fantail goldfish by its characteristic flowing, twin tailfin. It has double anal and caudal fins, with a dorsal fin that is held high. The male fantail develop white tubercules on their gill covers and the leading rays of their pectoral fins.

    • 3

      It has a compact, rounded, body shape and grows to about 6 inches (16cm).

    Ideal Tank Conditions

    • 4

      Obtain a 20-gallon (or larger) fish tank for your fantail goldfish. Increase this size by 10 gallons for each additional fish that you will have in the tank.

    • 5

      Clean your tank and fill it with room temperature water. Allow the tank water sit for twenty-four hours before you put in your new fish.

    • 6

      Invest in a powerful filter, because goldfish tend to release a lot of waste. Do a water change of 1/3 of the tank water each week to maintain the water quality.

    • 7

      Install your heater in the fantail's aquarium. Set the heater to maintain water temperatures between 40 to 77 degrees Fahrenheit (4 to 25 degrees Celsius).

    • 8

      Use the test kit to maintain water conditions at slightly acidic a pH range of 5 to 19 and dGH range of 6.0 to 8.0.

    • 9

      Spread your gravel substrate in the tank. Make sure that the gravel is pea-sized or larger, otherwise the goldfish may swallow some accidentally.

    • 10

      Add aquarium decorations as desired. If you want to have live plants, select hardy varieties, because goldfish tend to nibble on them. Hornwort, vals and anubias are a few hardy plants to consider.

    • 11

      Feed your fantail goldfish once a day. Provide only enough food as the fish can eat within five minutes. Provide high quality goldfish flakes or pellets, as well as frozen or freeze-dried brineshrimp, bloodworms or tubiflex worms. They are omnivorous and will also eat leafy vegetables such as collard greens and lettuce, as well as cucumber and peas.

    • 12

      Provide your fantails with some tank companions, which should ideally be fellow slow-swimmers like blackmoor goldfish, pearlscale goldfish, ryukins and other fantail goldfish.
