fish. After the fry is born, the first thing is to fish out the parent fish. For many fish, they do not take care of the habits of the larvae, but use them as food when they are extremely hungry, so it is best to separate the parent fish from the larvae. However, not all parent fish need to be fished out. For example, the betta fish does not need to be fished out. The male fish will protect the eggs, but the female fish should be fished out to avoid being attacked by the male fish.
every other day, because there are some yolk sacs when the fry is born, so the first day is not fed, until it has absorbed the yolk sac, it needs to be fed. Because the fish are too small to accept fish feed, they can only use water or cooked egg yolk as food. It should be noted that the cooked egg yolk needs to be wrapped in gauze and gently twisted into the water. If it is fed too much, the water will be damaged and the health of the fry will be affected.
oxygen should also be paid attention to when raising small fry. Because the fry is too small, the water temperature should be higher, which is not only conducive to its health, but also can accelerate its growth. According to the different types of fish, the temperature requirements are also different, generally 1-2 ℃ higher than the cultured fish. In addition, oxygen should be added to the fish tank to increase the oxygen content in the water.
Because the fry is extremely sensitive to water quality fluctuations, do not change water easily, it must be a week after hatching before the first water change. Moreover, the amount of water should not be too large, so as not to stimulate the fry.
