the newborn Mary fish? 1. Isolation: Mary fish should be isolated immediately after birth, because the female fish will be weak after birth, so it will be eager to find food to supplement physical strength, if not isolated in time, it is easy to eat the small fish as food.
2. Change the water: Mary fish is easy to pollute the water quality during the production period, so it is necessary to change the water immediately after the production. When changing the water, it is necessary to use tap water that has been exposed to the sun for more than 3 days. The amount of water changed does not need to be too much, and it can be controlled at one third or one quarter. When changing water, the current should not be too large to avoid hitting small fish, and the temperature difference between new water and old water should not exceed 2 degrees.
3, water temperature: Mary fish small fish just born, the constitution is weak, the breeder had better keep the water temperature at 25 degrees. This temperature is more suitable for their growth and development, and is also conducive to promoting their adaptation to the external environment.
to feed the newborn Mary fish? Because Mary fish is ovoviviparous, small fish can move on their own after birth, so the first day of birth can feed some cooked egg yolk or shrimp eggs and other live bait. First of all, we should pay attention to opening the circulating filtration system when feeding cooked egg yolk, because egg yolk is more likely to pollute the water quality. Secondly, attention should be paid to sterilization and disinfection before feeding live baits.
