Elegant and relatively hardy compared to some fancy varieties, it makes a striking, long-lived pond or aquarium fish for keepers prepared to give it plenty of room.\u003c\/p\u003e\n\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\n\u003cp\u003eGoldfish are a selectively bred, domesticated form with no true wild population; the Ryukin variety itself was developed from Chinese fancy goldfish stock and refined in Japan, bred purely for the aquarium and pond trade.\u003c\/p\u003e\n\u003ch2\u003eAppearance\u003c\/h2\u003e\n\u003cp\u003eA solid white body with the distinctive Ryukin high shoulder hump behind the head, a deep round body and a long, flowing twin tail fin.\u003c\/p\u003e\n\u003ch2\u003eTemperament and Compatibility\u003c\/h2\u003e\n\u003cp\u003ePeaceful and fairly slow-moving thanks to its ornamental fins, so it should only be housed with other similarly slow, cool-water fancy goldfish — fast or nippy tankmates will outcompete it for food or damage its fins.\u003c\/p\u003e\n\u003ch2\u003eFeeding\u003c\/h2\u003e\n\u003cp\u003eAn easygoing omnivore doing well on a quality goldfish pellet or flake, with occasional blanched vegetables (peas, zucchini) and frozen treats like bloodworm and daphnia.\u003c\/p\u003e\n\u003ch2\u003eCare Requirements\u003c\/h2\u003e\n\u003cp\u003eGoldfish are messy, heavy-bioload fish that need strong filtration and generous space no matter how small they look in the shop — a cramped tank is the single biggest cause of health problems in this breed. They're a cool-water fish and don't need (or want) tropical heating.\u003c\/p\u003e\n\u003ch2\u003eBreeding\u003c\/h2\u003e\n\u003cp\u003eAn egg-scatterer that will spawn in cooler water following a seasonal temperature drop and rise, typically in spring. Eggs are laid among plants or spawning mops and receive no parental care, so adults should be removed or eggs relocated to avoid them being eaten.\u003c\/p\u003e\n\u003ch2\u003eSpecies Information\u003c\/h2\u003e\n\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\u003eWhite Ryukin (Fancy Goldfish)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eDomesticated variety, developed in Japan\/China\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Size\u003c\/td\u003e\n\u003ctd\u003e15-20cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan\u003c\/td\u003e\n\u003ctd\u003e10-15 years, up to 20 with excellent care\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful, slow-moving\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eBeginner (but needs a large, well-filtered tank)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Tank Size\u003c\/td\u003e\n\u003ctd\u003e100L for one fish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Tank Size\u003c\/td\u003e\n\u003ctd\u003e200L+, adding around 50-100L per additional fish\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\u003e16-22°C (cool water)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e6.5-7.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003e8-18 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\u003eCool-water aquariums and ponds with other fancy goldfish\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 — will eat and uproot most soft plants\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\n\u003cp\u003eOther fancy goldfish varieties of similar size, shape and swimming speed — Ryukin, Oranda, Fantail and similar rounded, slow-moving breeds.\u003c\/p\u003e\n\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\n\u003cp\u003eAvoid tropical fish requiring warm water, fast or fin-nipping species, and slender-bodied \"common\" type goldfish or koi that will easily outcompete a Ryukin for food.\u003c\/p\u003e","brand":"Nick's Aquarium Oceanarium Terrarium","offers":[{"title":"Small (1-5cm)","offer_id":55232819855651,"sku":null,"price":24.95,"currency_code":"AUD","in_stock":false},{"title":"Medium (5-10cm)","offer_id":55232819888419,"sku":"AA2951","price":29.95,"currency_code":"AUD","in_stock":false},{"title":"Large (10-15cm)","offer_id":55232819921187,"sku":null,"price":34.95,"currency_code":"AUD","in_stock":false},{"title":"X-Large (15-18cm)","offer_id":55351968399651,"sku":null,"price":39.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/white_Ryukin_116affeb-96df-4f42-8aaa-277a99ab0c5f.jpg?v=1781697600","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/white-ryukin-carassius-auratus","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
