Ryukin Goldfish

Description
The Ryukin Goldfish is a popular fancy goldfish variety known for its deep, rounded body and distinctive high back or “hump” behind the head. Available in a wide range of colors—including red, white, calico, and bi-color—Ryukins are eye-catching and full of personality. They are hardy and active swimmers, making them a great choice for both aquariums and goldfish setups, provided they have ample space and strong filtration.
