Goldfish are a great starter fish to recommend for ponds and aquariums. The Calico Ryukin Goldfish has a white body with markings of red, orange and black. 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 or pond when full grown. They are considered diggers, so use caution when adding plants because they can get uprooted. 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.
