Water quality: two to three centimeters of Koi do not have high requirements for water quality. They can be raised by using tap water after drying. Water temperature: the most suitable living temperature for koi is 20-27 degrees Celsius. If it exceeds 30 degrees Celsius, Koi's appetite will weaken and its growth will be affected. Therefore, it is necessary to ensure that the curing temperature is between 20-27 ℃. Feeding: Koi seedlings grow faster and have a high demand for nutrients. They need to be fed two to three times a day. Food can choose earthworms, red worms, etc. 1、 How to raise two to three cm Koi fry 1. Water quality: Koi don't like hard water. Therefore, before raising, the water needs to be softened, otherwise the fry are difficult to adapt. If tap water is used for breeding, it is necessary to dry the tap water in the sun in advance to release chlorine from the water for breeding.
2. Water temperature: two to three centimeters of Koi seedlings do not have high requirements for water temperature. Just keep the water temperature at 25 ℃. If the water temperature exceeds 27 ℃, start oxygen to avoid anoxia of Koi seedlings.
3. Feeding: the two to three centimeter Koi seedlings are in a period of vigorous growth and have a high demand for nutrients. In addition to general fish feed, animal feed, such as earthworms and red worms, is also needed to promote the growth of Koi seedlings. Generally, feeding animal feed twice a week can meet their needs. 2、 How much water temperature is suitable for raising two to three centimeters of Koi fry? When raising two to three centimeters of Koi fry, keep the water temperature between 20-26 degrees Celsius. They don't have high requirements for water. They can be cultured with ordinary tap water. Their food requirements are not high, and the general fish feed can be fed. Koi seedlings are in the growth stage and consume a lot of oxygen. If the breeding density is relatively large, oxygen is needed. But if the density is not large, oxygen can not be given. （ErDaoSanLiMiJinLiYuMiaoZenMeYang，ShuiWenDuoShaoGeKuo）
