The Calico Ryukin Goldfish
Each specimen is unique with their combinations of colors. All Ryukin Goldfish have a hump right behind its head, curved backbone, fate belly and long fins. They are very hardy and will eat just about anything that is fed to them. Like most goldfish, the Calico Ryukin will get quite large and will need a large aquarium when full grown. They will eat just about any pellet or flake that you offer, however, be sure the food has vegetable foods in it. Freshwater food with vegetables will help prevent swim bladder problems.
