How about koi?

1, environmental requirements: koi and goldfish on the same water temperature, water quality requirements are not strict, the appropriate temperature range is 2℃~30℃, but can not resist sudden changes in water temperature, temperature difference suddenly exceeds 2℃~3℃ koi will appear uncomfortable, the optimal water temperature is 20℃~25℃; adequate oxygen needs, suitable for living in a slightly alkaline, low hardness water environment.

They can be reared anywhere from a fish tank to an outdoor pond, and they quickly grow to 30 centimeters long or larger, so a traditional indoor fish tank is not as good as a round plastic basin. Koi is a cold-water fish, so in the summer is relatively hot place to raise koi water depth of half a meter or more. The density of fish pond can refer to the density table of koi in fish pond; the density of aquarium is generally 60 cm ×30 cm ×15 cm, 6 koi carp with body length of 15 cm ~20 cm can be stocked; 9 cm ×30 cm ×50 cm can be stocked;110 cm ×30 cm ×50 cm can be stocked.

Summer: The weather is hot and hot, so it is necessary to cover the plastic shading net to prevent direct sunlight, so that the sunlight illumination is reduced from 8000~12000 lux to 5500~5800 lux.

③ Autumn: The weather is less rainy and sunny, the water temperature has dropped significantly, the most suitable koi growth, can increase the proportion of animal sex (protein), such as silkworm pupa, etc. Increase dosage to promote rapid growth.

④ Winter: The weather is cold. When the temperature drops to 0℃, koi should be transferred to indoor fish pond for overwintering in time. The indoor water temperature should be kept at 2℃~10℃. The key points are heat preservation, proper feeding, fat protection and disease prevention. From November to March of the next year, koi overwintering period.
