Zebrafish need to be isolated after spawning. Because if there is no isolation, the eggs produced are easy to be eaten up. In order to be able to hatch more and better, isolation is very necessary.
Before spawning, it is necessary to isolate the mother zebrafish from other fish to prevent them from affecting the spawning of the mother fish. At the end of their spawning, the mother fish and eggs should be separated immediately. They usually lay eggs from early morning to about 10 A. m. Usually, at about 10 o'clock at night, many fish eggs can be found to be white. These are unfertilized fish eggs that need to be sucked out to prevent them from polluting the water.
1. Water temperature: During reproduction, the water temperature should be adjusted to 25-26 ℃ as much as possible. The water temperature should not be too high or too low. If the water temperature is not suitable, it will seriously affect the success rate of reproduction.
2. Fish age: It is also a method to improve the success rate by selecting parent fish suitable for fish age for reproduction. It is better to choose 5-month-old fish, and the energy of the fish should be vigorous at best. If it can be raised alone, it is the best, they prefer to breed in the bottom of the tank, so in the bottom of the aquarium covered with clean pebbles, or nylon mesh board can also be.
