The proper way to raise goldfish mainly includes the following aspects:
Fish Tank Selection and Water Quality Management
Selecting a spacious and clean fish tank is the first step in raising goldfish. The size of the fish tank should be determined according to the type and number of goldfish. Generally, each goldfish requires at least 57 liters of water volume, and high - quality goldfish need even more water to ensure good living conditions. Regarding water quality management, new water should be exposed to sunlight or left standing for 2 - 3 days to remove chlorine and to bring the water temperature close to that in the fish tank. The optimal temperature for raising goldfish is between 20 - 28 degrees Celsius, and the best pH range is 7.5 - 8.5.
Feeding Methods
Feeding is crucial for raising goldfish. Goldfish are omnivores and require a reasonable combination of nutrients. Feed them 1 - 2 times a day, and adjust the amount of food according to the weather, season, and the size of the goldfish. In spring and summer, it is advisable to feed them early, usually around 6 - 7 a.m. In late autumn and winter, the feeding time can be a bit later, around 7 - 8 a.m. Never feed a large amount of food in the evening, especially after November, it is even less suitable to feed in the evening.
Water - Changing Methods
Changing water is an important way to keep the water clean. Generally, every day, only the dirt at the bottom of the fish tank and 1/10 - 1/5 of the old water need to be replaced, and then inject new water at the same temperature. In the hot summer and early autumn, the water in the fish tank can be rotated in a spiral shape. After it stands still for a while, use a rubber tube to suck out 1/3 - 1/2 of the dirt and old water in the center of the tank, and then inject new water of the same temperature and volume.
Disease Prevention and Treatment
Regularly check the health of goldfish to prevent diseases. Observe the activities and eating conditions of goldfish carefully every day, and frequently check the fish tank to prevent the invasion of harmful organisms. If a fish disease is detected, it should be examined under a microscope in a timely manner, and the right medicine should be applied according to the disease.
Common Problems and Solutions
Water Quality Issues: Change the water regularly to keep the water clean.
Disease Problems: Check regularly and treat diseases promptly when found.
Over - Feeding: Control the amount of food to avoid water pollution and health problems of goldfish caused by over - feeding.
Through proper management and care in the above - mentioned aspects, the death of goldfish can be effectively avoided, allowing them to grow healthily and happily.
