1. Cause: Swim bladder disorder is generally caused by too low water temperature or too large temperature difference in changing water. It is also possible that eating too much causes the digestive system to squeeze the swim bladder. This symptom is usually manifested by not swimming, floating in the water or lying on the side of the bottom of the tank. If you touch the diseased fish with your hand, they can return to normal temporarily, but they will return to their original state after a while.
2, remedial method: Can prepare buckle of a piece of organic glass, specific size should inspect the case of goldfish and decide. Tie the clasp with one end of the rope and the other end to the tail of the goldfish. In this way, the goldfish will slowly sink to the middle layer because of its weight. Then change water frequently, feed frequently, keep the water temperature at 25 degrees, and generally recover in about two weeks.
1. Reasons: There are many reasons for hypoxia, such as poor water quality and high feeding density. Generally, goldfish will come to the surface to breathe when they lack oxygen. If you find a goldfish floating on the surface of the water without swimming and opening its mouth all the time, it means that it lacks oxygen.
2. Treatment: You can reduce the feeding density, or change the water frequently. It's better to change the water once a week. The amount of water changed each time does not need to be too much, just a quarter. Oxygen pumps can also be installed to increase oxygen properly. Later, aquatic plants can also be planted in the fish tank to increase light appropriately, which can prevent goldfish from anoxia.
