Its body is silvery-white with five colors surrounding it: black, red, orange, blue, and silvery-white. They have a pointed head, rounded belly, and arched back. They are highly adaptable and relatively easy to keep. How to keep Calico Ryukin? Calico Ryukin fish care methods.
When choosing a fish tank, generally small glass tanks are suitable for keeping a limited number of fish. For example, a container measuring 40 cm long, 25 cm wide, and 30 cm high can hold 6 to 8 goldfish measuring 5 to 7 cm in length. Adult fish exceeding 8 cm in length should be kept in larger glass or ceramic tanks, with a small aerator provided as a backup to prevent oxygen depletion. The stocking density mentioned above is for reference only; the actual density should be determined based on water temperature, fish size, and water quality, and should not be followed rigidly.
For feeding and raising calico goldfish, live fish worms are the ideal food, as they don't easily spoil the water. Dried fish worms or artificial pellet feed are also acceptable. Live fish worms are available in the market. When buying dried fish worms, choose fresh, loosely granulated ones; avoid buying old or moldy dried fish worms. For artificial pellet feed, choose a complete feed with all the necessary nutrients.
To maintain clean water for goldfish, feeding should be strictly timed and measured, ideally once or twice a day. Each feeding should be small enough for the fish to finish within half an hour; overfeeding has two harmful effects: first, a full stomach increases metabolism and oxygen consumption, easily leading to suffocation and death; second, uneaten food spoils and ferments, deteriorating water quality and causing oxygen depletion. Maintaining water quality is crucial for goldfish. Regularly use a latex tube to siphon out accumulated waste, removing feces, uneaten food, and cloudy water from the bottom of the tank, then slowly add fresh water that has been left to stand for a day.
The above describes the methods for raising calico goldfish, which you can use as a reference.
