The Comet is a slim, athletic goldfish with a deeply forked, flowing tail, built for ponds and big coldwater tanks. It grows large, commonly reaching 25–30 cm and sometimes more, and is a long-lived, sociable fish for a spacious, unheated setup.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eThe goldfish is a domesticated fish, developed over centuries from wild crucian-type carp of East Asia. The Comet was bred in North America as a hardy, fast pond fish. Its ancestors live in cool, slow, weedy waters, and the Comet retains that love of cool, well-oxygenated space.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eA streamlined, single-tailed goldfish in solid metallic gold-orange, with long flowing fins and a distinctive deeply-forked, streaming tail that can be as long as the body. Unlike fancy goldfish it has a strong, torpedo-shaped body built for speed.\u003c\/p\u003e\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\u003cp\u003ePeaceful, active and social, happiest in a group. It is fast and greedy, so it should not be mixed with slow fancy goldfish or small fish it could outcompete or eat. Ideal as a group of comets in a pond or large tank.\u003c\/p\u003e\u003ch2\u003eFeeding\u003c\/h2\u003e\u003cp\u003eAn omnivore with a big appetite. Feed a quality goldfish pellet or flake as the staple, with vegetable matter, blanched greens, peas and occasional frozen foods. It produces a lot of waste, so feed sensibly and filter well.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eVery hardy and beginner-friendly, but its adult size and waste output demand serious space and filtration. A pond is ideal; in a tank it needs a large volume, strong filtration and cool, well-oxygenated water. It is a true coldwater fish and does not need — or want — a heater.\u003c\/p\u003e\u003ch2\u003eBreeding\u003c\/h2\u003e\u003cp\u003eAn egg-scatterer that spawns in spring as water warms, scattering sticky eggs over plants and pond margins. Adults eat the eggs, so dense planting or a separate setup is needed to raise fry, which are dark and colour up as they grow.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eCarassius auratus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eGold Comet Goldfish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eDomesticated (developed in North America from East Asian goldfish)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e25–30 cm (larger in ponds)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e10–15+ years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful (active)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eBeginner\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e200 litres (pond preferred)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003ePond or 400+ litres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eOmnivore\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e4–24 °C (coldwater; ideal 16–22 °C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e6.5–8.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003e5–25 dGH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003eNot applicable (freshwater)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003ePonds and large coldwater aquariums\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReef Safe\u003c\/td\u003e\n\u003ctd\u003eNot applicable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlant Safe\u003c\/td\u003e\n\u003ctd\u003eNo (digs and grazes soft plants)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eOther comets and single-tailed goldfish, and hardy coldwater pond fish such as other goldfish varieties, White Cloud Mountain minnows (in cool tanks) and, in ponds, appropriately-sized natives.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eSlow fancy goldfish (which it will outcompete), tropical warm-water fish, and any small fish that will be eaten or bullied by this large, fast feeder.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55232821559587,"sku":null,"price":10.95,"currency_code":"AUD","in_stock":false},{"title":"Medium (5-10cm)","offer_id":55232821592355,"sku":"AA1380","price":14.95,"currency_code":"AUD","in_stock":false},{"title":"Large (10-15cm)","offer_id":55232821625123,"sku":null,"price":19.95,"currency_code":"AUD","in_stock":false},{"title":"X-Large (15-30cm)","offer_id":55351969448227,"sku":null,"price":24.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/Gold_Comet_Goldfish_3e5b1387-0e75-4674-b106-c12995c09e29.jpg?v=1781697554","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/gold-comet-goldfish-carassius-auratus","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
