1, the reason: The fighting fish appears to lie down the situation possibly is the temperature difference is too big, causes them to appear the stress reaction. For example, when changing water, the temperature difference between new water and old water is more than 3 degrees Celsius, or in late autumn, the temperature difference between morning and evening is larger, and the breeder does not strengthen the heat preservation.
2. Solution: First of all, the breeder should keep the water temperature between 20 ℃ and 30 ℃, and ensure that the water temperature is constant. When changing water, pay attention to the temperature difference between the new water and the old water should not exceed 3 C. When changing water, the water flow should be as slow as possible to avoid impacting the fish body.
1. Causes: Betta lying horizontally may also be infected with bacteria. There are many causes of bacterial infection, the most common of which is poor water quality, bacteria breeding in the fish tank, or bacteria carried in the food fed.
2. Solution: The breeder can first raise the water temperature to 25-30 ℃, and then use oxytetracycline to medicate the sick fish, preferably once a day. After the medicated bath every day, it should be washed with clean water and then put into the original jar.
1. Cause: It is also possible to suffer from fish body loss of bladder, mainly caused by overfeeding. After suffering from the disease, the fish can not control the direction of their swimming, so they will lie in the tank and float around.
2. Solution: The breeder should first raise the water temperature to above 25 ℃, then add coarse salt to the fish tank, and finally lower the water level. If possible, you can cover the fish tank with black cloth and rest for 2-3 days. Stop feeding during treatment and change a small amount of water every day.
