Ranchu Goldfish, often referred to as the "king of goldfish," are cherished for their rounded bodies and lack of dorsal fin. Here are essential care requirements for keeping Ranchu Goldfish:

• Tank Size: Minimum 20 gallons for a single Ranchu, with an additional 10 gallons for each additional fish.
• Temperature: Maintain water temperature between 65-72°F (18-22°C) for optimal health.
• Diet: Feed a varied diet of high-quality flakes, pellets, and occasional live or frozen foods such as bloodworms and brine shrimp. Include vegetable matter like blanched spinach or peas.
• Tank Setup: Provide a spacious tank with a soft substrate to protect their sensitive bellies. Include smooth decorations and plants to create a stimulating environment without risking injury.
• Water Quality: Maintain excellent water quality with regular water changes (20-30% weekly) and efficient filtration to keep ammonia and nitrite levels low. Monitor water parameters regularly.
