After giving birth to their young, some female fish will have the behavior of protecting the eggs, and some will take the young fish to swim. Therefore, these fish can often be raised together with the eggs and fry, while others may not, and may swallow the eggs. Therefore, it is necessary to fish them out in time after spawning. Do not put it back into the original jar directly after fishing out, at this time it is still relatively weak, so it should rest alone for a few days, during which it should be fed with some mouth feed, so that it can recover.
1. Feeding: The newly laid young fish do not need to be fed on the first day. At this time, they can continue to absorb the yolk sac, which can supplement certain nutrition. The next day will be ready to cast food, conditional words, the best feeding back water. You can also feed cooked egg yolk, but just twist a little into the fish tank, which will pollute the water quality.
2. Change the water: Do not change the water frequently when raising small fish. As long as the water body is not particularly turbid, there is no need to change it. Therefore, changing water will certainly lead to stimulation of fish, once the stress response of small fish occurs, the mortality rate is still very high. In addition, we should also pay attention to keeping the water wet, and the temperature should be controlled at about 25 C.
3. Cleaning: Due to less water change, it is necessary to pay attention to the cleaning of the fish tank, and clean up the feces and residual bait in time, otherwise the water quality will deteriorate, which will be harmful to the health of the fry.
