1. Reason: It is possible that the water temperature is too low for parrot fish lying on the side at the bottom of the tank. Although they do not require high water temperature, if the water temperature is lower than 20 ℃, their activity and appetite will decrease. In addition, the water temperature at the bottom of the fish tank will be higher than that at the top, so parrot fish will lie at the bottom of the fish tank.

2. Solution: The breeder needs to raise the water temperature to 20-30 ℃ immediately. If conditions permit, it is recommended to install a heating rod to keep the water temperature between 25-30 ℃.

1. Reason: Parrot fish lying on its side at the bottom of the tank may be caused by poor water quality. Their metabolism is fast and their pollution to water quality is serious. If the breeder can't change the water in time, it will cause them to lie still at the bottom of the tank.

2. Solution: Breeders should change water immediately to ensure clean water quality. However, the amount of water change should not be too large, and it should be controlled at one third of the total amount of water. If conditions permit, it is best to install a circulating filtration system to slow down the deterioration of water quality.

1. Reason: Parrot fish lying on the bottom of the tank may also be sick, such as common white spot disease, water mold, enteritis, etc.

2. Solution: Breeders can give symptomatic treatment according to their specific performance. If the situation is serious, it is recommended to go to a special pet hospital for treatment.

1. Reason: Parrot fish lying on the side at the bottom of the fish tank may be caused by lack of oxygen, and their demand for oxygen is relatively high. If there is lack of oxygen, it will also cause them to lie in the tank.

2. Solution: Breeders need to get oxygen immediately to ensure sufficient dissolved oxygen in water. If conditions permit, it is best to give parrot fish oxygen for a period of time every day, so as to avoid hypoxia.
