after rear-end collision? Mary fish will give birth to small fish in about 20-30 days after rear-end collision. Usually, ordinary fish will give birth in 2-3 days after rear-end collision, but Mary fish is ovoviviparous, so it takes longer. If the environment in which Mary fish are raised is stable, the water temperature and quality are suitable, and the food is abundant, the time they need will be shorter. If the conditions are poor, the time for the young fish to mature will be longer, so the time for pregnancy will be longer. The belly of Mary fish will gradually expand after tailgating, and when their belly is obviously bigger, the breeder will need to keep them separately.
small fish born by Mary fish 1. Water temperature: Newborn Mary fish need higher water temperature, because they have poor adaptability to the environment, so breeders need to keep the water temperature at 28 degrees Celsius.
2. Water quality: Mary fish does not require high water quality, but after the birth of small fish, a small amount of water needs to be changed. Because Mary fish will pollute the water quality when they are produced, small fish can not be transferred to containers when they are born, and if the water quality is too poor, it will affect their development.
3. Feeding: Small fish do not need to be fed 1-2 days before birth. After 2 days, they can be fed with shrimp eggs, cooked egg yolk or water. At this time, the amount of feeding does not need to be too large, but the frequency of feeding needs to be higher. It is best to feed 2-3 times a day, and the amount of each feeding can be eaten within 5 minutes.
