after spawning? The map fish will eat the eggs after spawning, because the mother fish does not have the habit of protecting the eggs, especially after spawning, the mother fish's body will become weaker, they will find their own food to supplement their physical strength. If the breeder does not isolate them in time, the eggs are likely to be eaten up by the mother fish. Not only the females but also the males will eat the eggs, and it is best for the breeder to isolate the fish as soon as possible after spawning and fertilization. If isolation is not possible, nests can be placed in containers before they lay eggs, so that the eggs will adhere to them and can be easily removed.
after spawning? After spawning, the mother fish should be isolated first, because they will eat the eggs, so it is better to fish them out and raise them separately as soon as possible after spawning. If the eggs produced by the
map fish are fertilized successfully, they can continue to hatch. If fertilization is not successful, it needs to be fished out immediately to avoid polluting the water quality. The fertilized eggs will have a small black spot, and the unfertilized eggs will be white, which can be judged by the breeder after careful observation. The fertilized eggs can be hatched in the water temperature of 26 deg C for about 2 to 3 days, and do not need to be fed immediately after successful hatching, because the nutrition carried by the fertilized eggs is enough to be absorbed, so the fertilized eggs can be fed after 2 to 3 days.
