Basic Information
Identification & Characteristics
Identification
They have a short, fat body with a visible balloon belly. Unlike many other Fancy Goldfish breeds with unusual body shapes, they are very hardy and healthy. However, they are still susceptible to swim bladder issues. Ryukins are a bit more uncommon than standard Fringetails and they are a little more expensive too
Sexual Dimorphism
Females have rounder, thicker bodies and a rounder vent, while males are slimmer and have a more oval vent. Males often develop small white spots called tubercles on their gill covers and fins during breeding, and their pectoral fins are longer and pointier compared to the shorter, rounder fins of females.
Behaviour Details
Living in small groups , naturally found at mid-depth and near the bottom.
Water Parameters
