1. The water quality is too poor 1. Reason: If you don't change the water in the fish tank for a long time, the water in the fish tank will become worse. At this time, some microorganisms in the water will multiply in large numbers, and compete with rats and fish for living space, which makes rats and fish feel uncomfortable. They will jump to the water.
2. Treatment method: Take out one third of the water in the fish tank and replace it with a part of water with little difference in water quality with the original fish tank. Then add some nitrifying bacteria to the water, and remove harmful gases in the water by nitrification of nitrifying bacteria.
2. Hypoxia in water1. Reason: The oxygen dissolved in fish tank is a certain amount. Once the oxygen in the fish tank is consumed too much and not replenished in time, the rats and fish will float to the water to breathe.
2. Treatment: Add an oxygenator above the fish tank to oxygenate the fish tank, and stop oxygenating the fish tank after they recover.
3. Chlorine poisoning1. Reason: In family feeding, tap water is often used for rats and fish. However, tap water contains chlorine gas, which can lead to poisoning of rats and fish if it is not removed when changing water. At this time, they will float to the surface of the water.
2. Treatment: Add a little baking soda to the fish tank to remove chlorine from the water. But don't add too much, too much will do harm to rats and fish. Before changing water at ordinary times, it is necessary to remove chlorine from the added water in advance.
