1. Sick: If the zebrafish has been lying on the bottom of the water, it is likely to be sick. Some fish will have a poor constitution. Once there is any discomfort, it will be sick and not move.
2. Poor water quality: The water quality of zebrafish should not be too poor. For example, if there is residual food or some dirty things in the water, the fish will easily lie motionless at the bottom of the water.
3. Low water temperature: The water temperature should not be too low during the rearing period. It is a tropical fish. If the water temperature is relatively low, this situation will easily occur. If the temperature of the water is below 20 ℃, it may not move under the water. If zebrafish are kept in cold water for a long time, they will easily die.
If it is because the fish is sick, you can add some salt to the water first, but how to deal with it should be solved according to the actual situation, and the medication is different in different situations, generally using anti-inflammatory drugs or bactericides, but it should be noted that the dosage should not be too large. If the water quality is poor, it needs to be replaced in time. If the temperature of the old water in the fish tank is a little low, you can add a heating rod appropriately, and try to raise the water temperature to about 23 degrees Celsius.
