The newly hatched small fish must be raised separately from the big fish, because the big fish will eat the small fish intentionally or unintentionally. If they are not raised separately, the survival rate will be reduced, and the fry bred will eventually become a good meal for the big fish. They are usually isolated before breeding, and the parent fish are retrieved after spawning, so that the small fish can grow alone.
Because of the limitation of size, the newly fed small fish are often unable to eat meat and vegetables, and can only eat migratory water. The migratory water is rich in paramecium, which is the most suitable food for fish fry. If there is really no migratory water, you can also prepare to find a basin, twist a little egg yolk to the fish to eat, after eating, to fish back in time, in order to avoid deterioration of water quality.
The temperature must be well controlled when raising small fish. If the water temperature suddenly rises or drops, the survival of the fish will be threatened. Usually, a heating rod is placed in the fish tank to control the temperature. In addition, when changing water, we must be careful, violent water change will also cause changes in water temperature.
To change water for small fish can not be too frequent, too much water will cause it to be stimulated. Usually once a week is enough, of course, if the water quality deteriorates quickly, usually too much bait is fed, it is necessary to change the water in time, when changing the water, it is best to discharge the dirt at the bottom of the water.
