🐟 Black Ryukin Goldfish (Carassius auratus)
A Deep, Velvety Black Body • A Bold, High-Arched Back • A Long, Flowing Double Tail
📋 The Black Ryukin Goldfish carries a deep, velvety jet-black body with a bold, high-arched hump rising behind the head, a deep, rounded shape and a long, flowing double tail. This dark, dramatic form of the Ryukin combines a striking profile with a rich, glossy colour, and it makes a stunning contrast with brightly coloured goldfish.
It's a captive-bred fancy goldfish, developed in China and Japan. Every Black Ryukin Goldfish we ship is feeding well.
This is a lively, friendly, peaceful fish that glides gracefully around the tank and quickly learns to come to the front at feeding time. It's one of the hardiest fancy goldfish, thriving in a spacious aquarium with other fancy goldfish, and it grows up to 20cm, so a 100L tank suits it well.
