Origin:

China/Far east

Size:

Usually up to 8 inches. Goldfish have the potential to reach around 15 inches but this is uncommon. In the aquarium 7 – 8 inches is the average adult size.

Aquarium Size:

240 litres.

Preferred water conditions:

  • Temp: 10 – 23°C
  • pH: 7 – 8.5
  • Hardness: Hard

Diet:

Omnivorous, Goldfish are not fussy eaters at all and will consume anything they can fit in their mouth. A healthy diet of goldfish flakes and pellets is ideal in addition to treats such as bloodworm.

Behaviour:

Goldfish are peaceful but will eat anything they can swallow, including smaller fish and shrimp. They will also attempt to eat gravel/pebbles, so you will need to keep an eye on them. It has been known for goldfish to get pebbles stuck in their mouth.

Sexing:

Males are more slender than females and may develop white spots on the gill plates.

Breeding:

Goldfish are egg scatterers and like to spawn in plants. For a detailed guide on breeding Goldfish, click here.

Notes:

Goldfish are one of the most numerous aquarium fish. Whilst it is possible to keep Goldfish in a smaller tank, we feel that a 8 inch fish deserves some swimming room, this is why we recommend at least 240 litres for keeping Goldfish.
