Filtration \u0026amp; Maintenance\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eBlack Orandas are heavy waste producers and messy eaters. A robust filtration system—such as a large canister filter or high-capacity sponge filter—is essential to keep ammonia and nitrite levels at zero. Beginners must commit to routine weekly water changes of 25% to 30% to prevent bacterial issues like fin rot and maintain optimal long-term health.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e3. Feeding \u0026amp; Nutrition\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eDue to their deep bodies and modified digestive tracts, fancy goldfish are prone to buoyancy issues (swim bladder disease). Feed them high-quality sinking pellets or gel foods formulated specifically for goldfish rather than floating flakes, which cause them to swallow excess air. Supplement their diet regularly with blanched vegetables like peas, spinach, and zucchini.\u003c\/p\u003e","brand":"Goldfish","offers":[{"title":"Default Title","offer_id":57208029577556,"sku":"58672","price":6.96,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1052\/5828\/7444\/files\/BlackLionheadOrandaGoldfish_Carassiusauratus.webp?v=1789815711","url":"https:\/\/www.tropicalmarineaquatic.com\/products\/black-lionhead-oranda-goldfish-carassius-auratus","provider":"Tropical Marine Aquatic","version":"1.0","type":"link"}
