Red-crowned crane goldfish originated from China's auspicious bird - red-crowned crane, which is not only beautiful, but also a symbol of longevity. People have strict requirements for red-crowned crane goldfish. The red lump on its head must be square and thick, and only grow on the top of the head without extending to the cheeks. There is a red circle around the eyes. Its body is wide and short, silver-white, and without red patches. It has large tail fins that are the same length as the body, and it swims gracefully. In addition to the beauty of the red crown, people also have the meaning of "good luck" in their minds.
The so-called white spot disease, also known as white spot disease, is a common disease in goldfish during winter. Its main symptoms are: the fish's head and tail waving disorderly, loss of appetite, lazy to move in the corner of the fish tank, and small white spots on the body and fins. The reason is the indoor temperature fluctuates between highs and lows, resulting in fluctuations in the water temperature of the fish tank. When goldfish are found to be ill, they should be immediately isolated, and the white spots on the sick fish should be picked and removed with tweezers, and then put into a saltwater bath. After bathing, they should be kept separately, and when the fish recovers, they can be returned to the fish group. If all the fish in the tank suffer from this disease, red mercury can be dropped into the tank, one drop per kilogram of water, and the water temperature should be increased to twenty-seven degrees Celsius, avoiding fluctuations. When treating with the original tank water, the fish tank should also be darkened slightly. After the fish recovers, gradually replace it with new water until the water quality becomes clear.
1. Feeding: The feeding is all nutritious animal feed and white sesame, etc. Animal feed such as water flea, earthworm, yellow powder worm, green worm, leather worm, etc. The main feed is earthworm and white sesame. Red and black earthworms can be fed. Raw white sesame is the main feed. White sesame is easy to buy. Goldfish loves to eat it, easy to digest, and does not easily pollute the water quality. Do not feed poor quality goldfish feed purchased. Because this feed has too much starch, poor nutrition, difficult to digest, easy to pollute the water quality, goldfish eat malnutrition, goldfish growth will be slower, and it is easy to get sick. As long as the goldfish eats easily digestible food, it will not overfeed. When to feed, usually once in the morning and once in the afternoon, should not be overfed, eat until full. Otherwise, it will pollute the water quality.
2. Light: It is best to place the fish tank in a place where the sun shines for 1-2 hours. This can use the ultraviolet rays of the sun to sterilize. It plays a role in preventing diseases. This can reduce diseases. Try to focus on disease prevention and use medication as a supplement. At the same time, due to photosynthesis, the color of the fish is more bright and beautiful.
3. Water change: You must change the water regularly to increase the dissolved oxygen in the water. When changing water, only one-third to one-fourth can be changed. A lot of water cannot be changed at once, and the fish will not adapt. Keeping the water quality in the aquarium clear is very important. Fish can only grow fast when there is sufficient dissolved oxygen in the water. Otherwise, they will stop growing or even die. When to change the water, there is no definitive answer, it can be based on the water quality, change more when the water quality is turbid, otherwise change less.
4. Stocking density: For domestically bred rectangular aquariums with small volumes, do not raise too many fish, but few is better. For example, in a container with a length of 40 cm, a width of 25 cm, and a height of 30 cm, 6-8 small goldfish with a length of 5-7 cm can be raised. For example, in a circular glass tank with a diameter of 26 cm and a height of 13 cm, 4-6 small goldfish with a length of 4-6 cm can be raised. Adult fish with a body length of more than 8 cm should not be raised in small glass tanks, but should be raised in large glass tanks or ceramic tanks, and equipped with small oxygenating machines as a backup to prevent hypoxia. These stocking densities are just reference numbers and should be determined based on the water temperature, the strength of the fish, and the quality of the water. Mechanical actions should be avoided. Generally speaking, the larger the fish, the fewer fish should be raised; more should be raised in winter and fewer in summer; more should be raised when the water temperature is low and fewer when the water temperature is high. If you grasp the above points for domestically bred goldfish, you can certainly keep them healthy and lively, with bright colors, swimming in the water, loved by people, making you endlessly enjoyable. You can definitely raise them well. I wish you success.
