Lanshou goldfish always tilt 45 when swimming, but their appetite is normal and they don't wander. What happened?

You can compare the symptoms of swim bladder disorder of Lanshou golden fish to see if it is swim bladder disorder.

Swimming bladder disorder is easy to occur in winter or spring and autumn.

The symptoms of swim bladder disorder of Lanshou goldfish are: Lanshou goldfish lies on its side, stands upside down, floats on the water surface or sinks to the bottom. Generally, Lanshou goldfish will still take the initiative to eat and prey. But the goldfish floating on the water will fester and shrivel on the exposed side; Lan Shou, who sinks to the bottom of the water, will have symptoms of infection and inflammation because of the friction between his body and the fish tank.

The main reason of swim bladder disorder in Lanshou is malnutrition or low temperature in Lanshou, and the cure for this reason is to raise water temperature and strengthen nutrition. However, the common family-raised orchid longevity can also produce maladjustment, not only because of the temperature. The reasons include the following.

Overnutrition: Most families feed Lanshou for convenience, but most of the feed on the market at present is mainly based on the nutritional collocation of tropical fish. When raising orchid longevity, using such feed will make the nutrition exceed the growth needs of goldfish, leading to obesity, physical disorder and swim bladder disorder of goldfish.

Virus infection: According to relevant data, Rhabdovirus can cause inflammation and degeneration of the epithelial tissue of the swim bladder, accumulate a lot of body fluids in the fish, and oppress the body cavity tube, resulting in nowhere for the air in the swim bladder to go, and the ups and downs regulation function is effective. The sick goldfish was thin, dark, unresponsive and rolled upside down. Abdominal distension, abdominal ascites, ecchymosis on fish body surface, often complicated with enteritis. The sick goldfish will die in a week or so.

Changes in water temperature: Goldfish are cold-blooded animals and are sensitive to changes in water temperature. When the water temperature changes sharply, both rising and falling can stimulate the nerve endings of goldfish skin, thus causing the disorder of internal organs. The symptoms of the disease are that the skin loses its original luster, lying on its side on the water surface or bottom, and being lazy to swim. Goldfish, especially rare species, have been carefully cared for under artificial feeding conditions for a long time. When changing water, the old and new water temperatures are consistent, so they are more "delicate". When the water temperature suddenly changes above 3 degrees, it is easy to cause imbalance symptoms.

Physical factors: According to experience, the blue-shou golden fish is more prone to swim bladder disorder than other goldfish. The size factor is not the direct cause of swim bladder disorder, but these species are short in size and tend to lose their balance when they go downstream faster under normal circumstances. Therefore, once there is something wrong with the swim bladder, it is more prone to unbalanced symptoms.
