{"product_id":"black-ranchu-goldfish-12cm","title":"Black Ranchu Goldfish 12cm","description":"\u003cp\u003eThe Black Ranchu Goldfish is a highly appreciated variety of fancy goldfish, often called the \"King of Goldfish\" due to its unique appearance and royal status among aquarists. Developed originally in Japan from the Chinese Lionhead, this specific color morph is celebrated for its deep, velvet-black coloration.\u003c\/p\u003e\n\u003cp\u003eDistinctive Features\u003c\/p\u003e\n\u003cp\u003eNo Dorsal Fin: The completely smooth, downward-curving, arched back is their most famous trait.\u003c\/p\u003e\n\u003cp\u003eThe \"Wen\": As they mature, they develop a fleshy, brain-like head growth known as a hood or wen.\u003c\/p\u003e\n\u003cp\u003eEgg-Shaped Body: They have a very round, compact, stout body with a short, tucked-in tail fin.\u003c\/p\u003e\n\u003cp\u003eColor Shifting: Their dark pigment is caused by high melanin. Genetics, water quality, sunlight, or aging can sometimes cause their color to shift to bronze, orange, or white over time.\u003c\/p\u003e\n\u003cp\u003eQuick Care Overview\u003c\/p\u003e\n\u003cp\u003eTank Size: Minimum 100 liters (approx. 30 gallons) for a single fish. They are slow, clumsy swimmers that require plenty of horizontal swimming space.\u003c\/p\u003e\n\u003cp\u003eWater Temperature: Prefers a stable temperature between 18°C and 24°C (64°F - 75°F).\u003c\/p\u003e\n\u003cp\u003eDietary Needs: Omnivorous feeders. They should eat high-quality sinking pellets and occasional fresh treats like brine shrimp. Sinking food is best because their body shape makes them susceptible to swim bladder issues if they gulp surface air.\u003c\/p\u003e\n\u003cp\u003eTank Mates: Keep them strictly with other slow-moving, dorsal-less fancy goldfish (like other Ranchus or Lionheads). Faster fish will easily outcompete them for food.\u003c\/p\u003e","brand":"Jasmin Aquatics Store","offers":[{"title":"Default Title","offer_id":53427253149993,"sku":null,"price":56.5,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/4325\/2521\/files\/Micro-Pellets_20260814_165308_0000.png?v=1786712146","url":"https:\/\/jasminaquaticsstore.com\/products\/black-ranchu-goldfish-12cm","provider":"Jasmin Aquatics Store","version":"1.0","type":"link"}
