Many people have large homes with yards, and whether for hobbies or to beautify their home environment, they often keep plants and ornamental fish . Among ornamental fish, most ordinary people are probably most familiar with koi and goldfish . So, can goldfish and koi be kept together?
Can goldfish and koi be kept together?
Strictly speaking, yes, anyone can keep them as long as they don't die. However, keeping goldfish and koi together carries certain risks.
However, it's unlikely that koi won't bite goldfish, and some goldfish varieties are not suitable for mixed keeping, such as pearl gourd , pompom gourd, and Ranchu. If kept together in a fish tank , goldfish may not adapt well to the strong water flow environment of the koi. Larger goldfish and smaller koi might be slightly better kept together. In general, goldfish and koi differ in their living habits, eating habits, size, and water quality requirements; keeping them together requires careful consideration of many factors.
Precautions:
1. Ensure the aquarium is the right size to provide enough space for swimming.
2. Ensure they all receive adequate diet and nutrition.
3. Ensure the water quality is suitable to meet their living habits and needs.
How often should you change the water when keeping goldfish?
Goldfish don't need their water changed too frequently. Depending on your situation, if the water is very cloudy or the goldfish are lacking oxygen, change it immediately. You can also use a tubing to siphon out a small amount of goldfish feces and debris from the bottom of the tank each day. In summer, change the water every 3-4 days; in autumn and winter, change it every 7 days; and in winter, change it every 15 days.
