1. Normal phenomenon 1. Reason: Zebrafish likes to move in the middle and upper layers, especially when resting or sleeping, and often floats on the water.
2. Solution: This is a normal phenomenon. Breeders should not disturb them to avoid them being frightened or stimulated.
2. Hypoxia1. Reason: Zebrafish floating on water may be caused by hypoxia, and zebrafish has a high demand for oxygen. If breeders can't guarantee regular oxygenation, they will suffer from lack of oxygen. In addition, when there are too many fish in the fish tank, the oxygen in the water will also decrease, and they will also suffer from lack of oxygen. When there is too little oxygen in the water, they will float to the surface to get oxygen.
2. Solution: If the breeder has the conditions, it is best to install an oxygen pump for them and give them oxygen immediately to ensure sufficient oxygen in the water. If there is no oxygen pump, you can increase the oxygen in the water by changing the water. 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.
3. Sick1. Reason: Zebrafish may be sick when they float on the water. When they are seriously ill, they will have weak limbs and float on the water.
2. Solution: Breeders need to judge the etiology according to their manifestations and symptoms, and then treat them symptomatically.
