1, water quality: Young fish need to be raised in a tank with a filtration system to ensure that the water quality is up to standard. The water should not be changed too frequently or not at all within one month after the birth of the young fish. Change the water about every 10 days or so, about a quarter of the water can be changed each time.
2. Feeding: Newborn black Mary fish should be fed with feed that is easy to digest and has small particles. Specifically, it is recommended to use egg yolk water, shrimp egg debris and other foods as feed. Feeding should be done with a small number of meals, 2-3 times a day, each time a small amount of feeding.
For breeding black Mary fish, it is recommended to use water with water temperature between 25-28 ℃. Such water temperature can keep the young fish growing, so that they can grow better and faster. If the water temperature is low, they may grow very slowly and even have some growth problems. If conditions permit, a heating rod can be installed inside the tank to maintain the water temperature.
When raising small black Mary fish, it is recommended to raise them alone. Don't keep them with other fish, and don't keep them with adult black Mary fish, or they may be eaten.
