1. The water temperature is too low: The newborn black Mary young fish is not strong enough to adapt to the water temperature. If the water temperature is very low, they will not be able to grow normally. When the water temperature is very low, the small fish may die.
2. The water quality is too poor: Young black Mary fish also have higher requirements for water quality than adult fish. If the aquaculture water is too acidic, dirty and muddy, so that young fish can not adapt, they may die ahead of time.
3. Environmental mutation: Newborn Mary fish likes relatively stable environment and can not adapt to rapid changes in the environment. If the water temperature, acidity, alkalinity, hardness and other indicators of aquaculture water suddenly change greatly, they may also die because they can not adapt to it.
4. Forget to feed: The small fish do not need to be fed for 1-2 days after birth, but they should be fed on the third day. If they are not fed for a long time, they will not get enough nutrients to sustain their lives, and they will die.
5. Being eaten: Black Mary Fish Small fish are very small, and if there are other large fish in the tank, they are likely to be eaten. In addition, the parent fish of the black Mary fish may also eat their own raw fish.
In order to prevent the black Mary fish from dying, they should be raised separately in a fish tank, and should not be mixed with other fish. When breeding, the water temperature should be controlled between 25-28 C, clean water with weak alkalinity should be used, and the water quality should be stable. Also pay attention to feeding 2-3 times a day to provide them with nutrients to help them grow.
