1. Reason: Parrot fish is a tropical fish, which needs suitable temperature to grow better. In the absence of disease, if the water temperature is too low, they will die together.
2. Treatment method: First, raise the water temperature and maintain it at 25-30 ℃. When changing water, we should also pay attention to the temperature difference should not be too large, and try to keep the temperature difference at 0.5 C.
of water quality 1. Reason: It is suitable for living in soft water with weak acidity, so it has higher requirements for water quality and needs to be raised in soft water with weak acidity. If the water quality is not suitable, or there are more impurities in the water, they may die together.
2. Handling method: Keep the water clean. A nitrification system is established to decompose nitrite in fish feces, convert harmful substances in fish feces into harmless substances, prevent bacterial growth and keep water clean.
supply 1. Reason: Parrot fish has a congenital defect that its mouth and gills cannot be closed, so it has a high demand for oxygen. If there is too little dissolved oxygen in the water in which they are raised, they will not be able to adapt and die in piles.
2. Treatment method: When they are found to be anoxic, a suitable oxygen supply system should be installed in the tank to oxygenate them. When feeding, the oxygen supply system should be checked regularly, repaired and replaced to ensure adequate oxygen sources. This will greatly reduce the phenomenon of its cluster death.
