1. Cause: a sudden increase or decrease in water temperature will inhibit the activity of the fish, causing the fish not to swim. Moreover, the sudden change of water temperature can easily stimulate the fish. When it can't accept the change of temperature, it will become inactive.
2. Handling method: Control the temperature not suddenly high suddenly low. The temperature is adjusted to 25 deg C to 28 deg C, so that the fish can live under the most suitable temperature condition. When changing water, the temperature difference should not exceed 0.5 C, so as to avoid the fish being stimulated again.
1. Reason: Parrot fish are very timid. If it is frightened, it will hide at the bottom of the tank and not swim, thus reducing its sense of existence.
2. Treatment: In addition to feeding, try not to disturb it. This situation is not very serious. After a while, when the fish feel safe around them, they will come out and move.
1. Cause: The oxygen content in the water is so low that the fish can't breathe normally. In a relatively anoxic environment, fish will try not to swim to reduce their oxygen consumption.
2. Treatment method: The dissolved oxygen content of new water is higher than that of old water, so the oxygen content in water can be increased by changing water. You can also use an oxygen pump to pump oxygen directly into the water. However, the oxygen pump can not be kept on all the time, and it can be oxygenated for 1 to 2 hours a day.
