The fry can be fed the next day after birth. Newborn fry can continue to consume the nutrition in yolk sac, and they will start feeding every other day. Usually, we should choose backwater when feeding it. If not, we can use cooked egg yolk. Don't feed too much every time, so as not to pollute the water body. In addition, you can also prepare a special fish tank for feeding, and then put the fry back into the original tank after eating.

1. Feeding: Pay attention to feeding first when raising small fry. The newly hatched fry need not be fed on the first day, and it can also absorb yolk sac for nutrition. By the next day, the yolk sac was basically absorbed. At this time, food needs to be fed. The best food is backwater, but cooked yolk can also be fed, but not too much, otherwise the water will be bad.

2. Change water: Because young fry are sensitive to water quality, change water too early, and usually change water for the first time after hatching for one week. Pay attention to the amount of water when changing water. If you change too much water at one time, it will also stimulate the fry. Usually, it is enough to change about a quarter, and the temperature should be consistent before and after changing water.

3. Temperature control: Small fry also require temperature. In order to make them grow as soon as possible, the temperature should be appropriately higher, usually 1-2 ℃ higher than that of cultivated fish, so that metabolism is vigorous, not only grows fast, but also is not easy to get sick.
