Ranchu Goldfish are another type of fancy goldfish like Orandas. They are highly prized for their unique appearance, characterized by their lack of a dorsal fin and a rounded body shape. Ranchus have a distinctive hump on their back, often referred to as a "hood." These goldfish come in various colors and patterns, adding to their charm. Ranchus, like other fancy goldfish, require good water quality, space to swim, and a balanced diet to thrive. They are known for their friendly and social nature, making them delightful pets for aquarium enthusiasts.
