2. The breeding environment of yellow koi fish
1.Water quality requirements: Yellow koi has high requirements for water quality. It needs to keep the water clean, the pH value should be controlled between 7.0-7.5, and the ammonia nitrogen and nitrite content should be close to zero.
| water quality parameters | ideal range |
|---|---|
| pH value | 7.0-7.5 |
| Ammonia nitrogen | <0.02mg/L |
| nitrite | <0.1mg/L |
2.Fish tank or pond selection: Yellow koi fish need a large space for activities. It is recommended to use a fish tank or outdoor pond of at least 1 meter. Outdoor ponds need to be equipped with shading facilities to prevent direct sunlight from causing excessive water temperature.
3.Filtration system: A powerful filtration system is key to maintaining water quality. It is recommended to use a combination of biochemical filtration, physical filtration and plant filtration to clean the filter material regularly.

Precautions:
- Change the water regularly (change 1/3 of the water every week).
- New fish need to be quarantined and observed for 1 week before entering the tank.
- Avoid feeding spoiled feed.
5. Reproduction techniques of yellow koi fish
The reproduction of yellow koi fish requires specific conditions:
| breeding conditions | request |
|---|---|
| Broodstock selection | 2-3 years old, healthy and disease-free |
| water temperature | 18-22℃ |
| spawning ground | Aquatic plants or artificial ovaries |
Things to note during breeding:
- The appropriate male to female ratio is 1:2.
- Remove the brood fish promptly after spawning to avoid swallowing fish eggs.
- Keep the water quality stable during the hatching period of fish eggs and avoid strong light exposure.
6. Summary
Raising yellow koi requires patience and care. From water quality management to feeding techniques, every aspect is crucial. Through scientific feeding methods, you can not only appreciate the elegant swimming posture of yellow koi fish, but also witness the joy of their healthy growth.
