Prevention and treatment of swim bladder diseases;

As with any disease, prevention is better than cure. According to the above causes of swim bladder disorder. Pay attention to the following points in the process of family feeding:

1. Don't rush to feed the newly bought goldfish with artificial feed. At first, feed some fresh Daphnia. A week later, the goldfish adapted to the new environment, and began to feed a small amount of artificial feed after physical recovery. Try to choose flaky feed, which has strong water absorption and is not easy to swell again in goldfish intestines, causing constipation. Granular feed can be smashed with a hammer before feeding. Powdered feed is not recommended because it is easy to oxidize and deteriorate. When feeding, always observe the feces of fish. If there is no feces or white feces, stop feeding for a few days.

2. Goldfish had better be fed with live bait and artificial feed alternately, and fed with green feed. In sunny breeding places, goldfish can eat the moss attached to the pool wall by themselves. Aquarium culture can stick plant feed patches on the tank wall for goldfish to eat at will. It is best to buy artificial feed specially developed for goldfish to prevent nutritional imbalance.

3. Before changing the water in the aquarium, put fresh water near the aquarium, measure the water temperature with a thermometer, and then change the water after confirming that the water temperature is consistent. Pay attention to the maintenance of water quality on weekdays (see the author's last article), so that goldfish can have a comfortable living space and a strong body can resist the invasion of viruses and germs.

4. For beginners to raise goldfish, when choosing goldfish varieties, it is best to start with general varieties and choose grass goldfish, dzi beads and other varieties for breeding. These varieties can adapt to rough and extensive feeding methods. Don't choose individuals who are too thick and too short for precious varieties.

For sick goldfish, it is necessary to keep them in isolation or use small cages floating on the water. The water level should not be too high, as long as it can pass the fish. If the water temperature is below 20 degrees and the isolation tank is not too small, there is no need to use oxygen-increasing facilities to reduce the energy consumption of goldfish passive swimming. And add one thousandth of the original salt to the water to inhibit the growth of bacteria in the water. And slowly raise the water temperature to above 15 degrees. At the beginning of illness, you can change some green feed, such as duckweed. Goldfish may not like it at first, but they will get used to it after stopping feeding other feeds for 2-3 days. Generally, goldfish can return to normal in a week or so. For goldfish imbalance caused by gastrointestinal obstruction, you can refer to the treatment of enteritis. For seriously ill fish, if they are lying on their side on the water, you can insert a small syringe into the position of the swim bladder from the side to extract some gas. Relieve symptoms. (This operation needs to be very familiar with the anatomical structure of different goldfish varieties, which is risky. ) For sick fish lying by the water, you can tie foam plastic to the dorsal fin and let the sick fish suspend upright in the water. Egg fish without dorsal fins can use small cages to isolate the bottom of the tank. For seriously ill fish, after the above treatment, the life span can be extended by about one year at most.
