1. Hypoxia: Parrot fish has a high demand for oxygen because its lips are not closed tightly. If the breeder stops taking oxygen or the dissolved oxygen in the water suddenly decreases, they will die of lack of oxygen.
2, sudden change of environment: The sudden death of parrot fish may also be caused by sudden change of environment. Although they have low requirements for the environment, they are sensitive to the changes of the environment. If the temperature and quality of the water in which they are raised change greatly, they will die suddenly.
3. Overfeeding: Parrot fish die suddenly after feeding too much. Although they eat a lot, if the breeder feeds too much food, they will eat too much. Coupled with their inability to digest more food, they will die.
2. How to raise parrot fish is not easy to die1. Stable environment: To make parrot fish not easy to die, it is necessary to ensure that their living environment is comfortable and stable. As long as the water temperature and quality do not fluctuate violently, they will not die suddenly.
2. Reasonable feeding: It is best to follow a small number of feeding methods for parrot fish, which can not only ensure their adequate nutrition, but also reduce indigestion.
3. Adequate oxygen: Parrot fish have a high demand for oxygen, so breeders need to give them oxygen every day to ensure sufficient dissolved oxygen in water.
