Mary fish can complete a reproduction in about 35 days after entering the breeding period. Because Mary fish is born as a small fry, it will take longer to conceive than other fish. Generally speaking, without outside intervention, it will take about a month from pregnancy to birth. If the ambient temperature is below 25 C, its pregnancy time will be prolonged. If the abdomen of the female fish is observed to be bulging and the anus is very prominent, young fish will be born in 2 to 5 days.
1. Isolation: Newborn Marlies should be isolated from their parents immediately. Because the small fry is too small, it is easy to be used as food by big fish in the water. Even if there are only parent fish in the tank, if they are not isolated immediately, the parent fish will eat them all.
2. Temperature: The most important thing in keeping small fish is the temperature. The newborn fry has poor adaptability and should be provided with the most suitable growth environment. The temperature should be controlled between 22 and 26 C. At this time, the activity of fish is relatively high, which is also good for its development.
3. Change water: In order to ensure the stability of water quality, just a few days before birth is not the need to change water. But if the water is already very muddy, you must change the water. It is not necessary to replace all the water when changing the water, just take out one third of the old water and add warm new water.
4. Feeding: Mary Fish do not need to be fed when they are first born. About two days later, it will open its mouth to eat. When the fish has just opened its mouth, it is best to feed it with egg yolk water. After it can eat normally, it can be fed with plant feed and fresh bait.
