? If the parent fish has just been produced, the water can be changed, but the amount of water can not be too large, preferably controlled at one fifth of the total water volume. If the water quality is not very bad, you can change the water 2-3 days after they are born.
If they are newborn fish, they can not change water, because they are weak in constitution and adaptability. If the water is changed immediately, it will make them uncomfortable, and the weaker fry are likely to die directly. During this period, filter pumps can not be used, because the size of guppy fry is small, it is easy to be sucked away by filter pumps. If the breeder wants to change the water, he can wait for 3-7 days and change a small amount of water. When changing water, the change of PH value should not exceed 0.5.
fed? Newborn guppies can't be fed. They have their own nutrients from their mothers, which are enough for them to absorb for 2-3 days, so they don't need to be fed for 3 days after birth. After 3 days of birth, you can feed some shrimp or cooked egg yolk to the fry, a small number of times, every 2-3 hours is the best. A week after birth, you can eat some synthetic feed or animal feed, which can be fed 2-3 times a day.
