Like other fancy goldfish, they are peaceful, social fish that are slower swimmers than single-tail varieties, so they need suitable tank mates, strong filtration, and plenty of space. They are not suitable for bowls or tiny tanks. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"830\" data-end=\"1103\"\u003e\u003cstrong data-start=\"830\" data-end=\"845\"\u003eCare Level:\u003c\/strong\u003e Easy to moderate\u003cbr data-start=\"862\" data-end=\"865\"\u003e\u003cstrong data-start=\"865\" data-end=\"881\"\u003eTemperament:\u003c\/strong\u003e Peaceful, social, and slow-moving\u003cbr data-start=\"915\" data-end=\"918\"\u003e\u003cstrong data-start=\"918\" data-end=\"935\"\u003eMaximum Size:\u003c\/strong\u003e Usually around \u003cstrong data-start=\"951\" data-end=\"963\"\u003e15–18 cm\u003c\/strong\u003e in aquariums is a practical expectation for fancy goldfish, though size can vary with setup and care. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1105\" data-end=\"1426\"\u003e\u003cstrong data-start=\"1105\" data-end=\"1127\"\u003eMinimum Tank Size:\u003c\/strong\u003e\u003cbr data-start=\"1127\" data-end=\"1130\"\u003eA sensible minimum is around \u003cstrong data-start=\"1159\" data-end=\"1195\"\u003e75 litres for one fancy goldfish\u003c\/strong\u003e, with roughly \u003cstrong data-start=\"1210\" data-end=\"1254\"\u003e40 litres extra for each additional fish\u003c\/strong\u003e.
