1. Environment: During the breeding period of angelfish, the two parent fish should be separated from other fish to avoid the problem of spawning affected by the external environment.
2. Water quality: The water quality during the breeding period should still be weakly acidic water with a PH value of about 6.5. You can use methylene blue to sterilize before putting in the fairy. In order to keep the environment stable, old water can be used without changing water. After laying eggs, they need to use oxygen pump to pump more oxygen in the hatching tank.
3. Water temperature: In general, the water temperature needs to be raised to about 27 ℃.
4. Light: Five to six hours of light per day is needed to provide adequate light.
5. Feeding: The young fish usually hatch within two days, but the young fish will remain on the farrowing board. About a week before swimming, after which you can feed some cut fish and insects.
Generally, it needs to be isolated for hatching. After the angelfish lays eggs, in order to prevent other fish from interfering and create a suitable environment for them, it is necessary to isolate them for hatching. Hatching angelfish eggs generally requires maintaining the water temperature at about 27 degrees Celsius, using weak acidic old water, and providing adequate light. Therefore, they need to be isolated in general.
