Their flowing fins and varied color patterns make them a popular choice for aquarium enthusiasts. Typically reaching a size of 6-8 inches, Ryukins are known for their hardiness and playful demeanor.  \u003cstrong\u003eOrigin:\u003c\/strong\u003e Originally from China, Ryukin Goldfish have a rich history dating back centuries. They were later introduced to Japan, where they became highly popular. Today, they are bred worldwide.  \u003cstrong\u003eFeeding:\u003c\/strong\u003e Ryukins are omnivores and thrive on a varied diet. High-quality goldfish pellets or flakes should form the basis of their diet, supplemented with live, frozen, or freeze-dried foods like bloodworms, brine shrimp, and daphnia. Vegetable matter like blanched spinach or peas is also beneficial. Avoid overfeeding as they are prone to digestive issues.  \u003cstrong\u003eTank Mates:\u003c\/strong\u003e Ryukin Goldfish do well with other goldfish varieties, particularly those that are not too fast-swimming or competitive for food. Suitable companions include Orandas, Telescopes, and Fantails. Avoid pairing with aggressive or nippy fish.  \u003cstrong\u003eAggression:\u003c\/strong\u003e Ryukins are generally peaceful but can be competitive during feeding. They are better suited to a community of similar, non-aggressive goldfish species.  \u003cstrong\u003eExperience Level:\u003c\/strong\u003e Suitable for beginners to advanced aquarists, Ryukins are relatively easy to care for, provided their basic needs are met.  \u003cstrong\u003eWater Parameters:\u003c\/strong\u003e \u003cul\u003e  \t\u003cli\u003eTemperature: 65-75°F (18-24°C)\u003c\/li\u003e  \t\u003cli\u003epH: 6.5-7.5\u003c\/li\u003e  \t\u003cli\u003eWater hardness: 5-19 dGH\u003c\/li\u003e \u003c\/ul\u003e Regular water changes and a well-maintained filtration system are crucial to keep their environment clean and healthy.","brand":"SimsTF","offers":[{"title":"5cm","offer_id":64946713362809,"sku":"STF-RYUKIN-CALICO-5cm","price":11.0,"currency_code":"GBP","in_stock":true},{"title":"10cm","offer_id":64946713395577,"sku":"STF-RYUKIN-CALICO-10cm","price":22.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1026\/3124\/4153\/files\/Calico-Ryukin.png?v=1792492816","url":"https:\/\/birchwoodaquatics.myshopify.com\/products\/calico-ryukin-goldfish-carassius-auratus","provider":"Birchwood Aquatic Centre","version":"1.0","type":"link"}
