CATDOLL : CATDOLL: How long can a goldfish live?

1. How long can a goldfish live?

The lifespan of a goldfish is related to its breeding conditions and physical condition. It is generally believed that the lifespan of a goldfish is only 6-7 years, but some people have observed that goldfish can live for more than 10 years or even longer under good breeding conditions.

A goldfish that was just included in the Guinness Book of World Records as the world's longest-lived goldfish has died. This goldfish was bought by a man named Hunter from North Yorkshire, England, for his then 7-year-old son in 1956. 43 years have passed, Hunter's son has already started a family, and this goldfish, which is about 43 years old, has turned from copper to silver. Hunter, now 72, said sadly that he had a deep affection for the goldfish, and the goldfish knew his face and he also understood the goldfish's mood.

2. What is the normal water temperature for tropical fish?

The water temperature for tropical fish is generally controlled between 24 and 28 degrees Celsius. Within this temperature range, tropical fish have a strong appetite and grow rapidly. They are not affected by changes in external temperature and always maintain a relatively stable state. Tropical fish baits include fish worms, water earthworms, fiber worms, mealworms, small live fish, granular feeds, etc. There are many varieties of tropical fish, and the sizes vary greatly, so the choice of bait for different varieties of tropical fish is also different. For tropical fish with a body length of 3-12 cm, the bait is mainly turtle worms, supplemented by water earthworms, bloodworms, and mealworms. For tropical fish with a body length of more than 12 cm, turtle worms are small and have poor palatability. Slightly larger baits should be selected, mainly bloodworms, water earthworms, mealworms, small live fish, etc. Most tropical fish are mainly fed with animal baits, and small varieties can also be domesticated to feed mainly with granular feeds, while there are very few fish that are mainly fed with plant baits.

3. Tips for raising goldfish

Feed goldfish in moderation, not too much. Overfeeding goldfish may lead to bloating and death. So how to identify whether it is in moderation? This can be identified by the color of the goldfish's feces. If the feces are brown or ink-colored, it indicates that the feed is appropriate; if the feces are grayish white or light yellow, the feed may be too much. Do not feed the goldfish immediately after you buy it. First feed it with a small amount of bloodworms or other artificial feed, and then switch to normal feeding. Feed goldfish three times a day. Goldfish feed is mainly composed of protein, minerals, carbohydrates and vitamins, such as mosquito larvae, earthworms, water plants, fine noodles, wheat meal, etc. Goldfish are most afraid of oily foods, such as biscuits, cakes, etc. Therefore, do not feed these foods to goldfish.

The main feed for goldfish is water fleas (commonly known as water maggots, fish worms, and red worms), which grow in various mud ponds. Before putting them in, they should be rinsed with clean water once; they can also be made into dried water fleas for storage. The method is to spread a layer of live water fleas on the glass, dry them into a thick piece, and when they are used, take a piece and put it in water, and it will dissolve by itself. In addition to water fleas, water worms, earthworms, cooked meat, cooked egg whites, crab eggs, noodles, rice grains, bread, steamed buns, etc. can also be used as feed, but the latter two need to be pinched into small particles before feeding. Among these feeds, animal feeds are better. The daily feeding amount should not be too much, and it should be eaten within two hours. For 3 to 4 fish of about 1 inch long, one spoonful of fish worms with water is enough, and bread and rice grains should be fed less.

4. How to raise goldfish well

Goldfish are natural living works of art, with peculiar shapes, bright colors, and graceful movements. They are loved by the Chinese people. Here are some ways to raise goldfish at home:

1. First of all, you should pay attention to "water". The saying "fish and water have a good relationship" fully explains the relationship between fish and water, and the importance of water to fish. Clean lake water, river water, well water, spring water, and tap water can all be used to raise goldfish. However, well water must be placed in a bucket for two days before use, because well water is warm in winter and cool in summer. If it is used directly, it is easy to cause the water temperature in the fish tank to change rapidly, causing goldfish to catch a cold. Tap water contains the smell of chlorine and bleach, and it must be exposed to the sun for two or three days to remove the smell before it can be used (if it is in winter, it needs to be placed for two more days). Therefore, most fish breeders are accustomed to preparing clean water in a container for use, rather than finding water temporarily and using it. Beginner fish breeders often do not understand this principle, which leads to the death of fish.

The water in the fish tank needs to be changed, but it should not be changed frequently and completely. Under normal circumstances, you can pump out the dirt under the water every morning, pump out about a quarter to a third of the water, and then add new water for spare. If it is the plum season or hot weather, you should change more water. Pay special attention to the fact that sometimes the fish float on the water surface and half stick their mouths out of the water to breathe. Even if people hit the edge of the tank with their hands, they will not be startled and will still float on the water surface, or they will immediately float up to the water surface to breathe after sinking.

This phenomenon is called "water screaming", which means that the water is seriously lacking in oxygen. The water should be completely replaced immediately and replaced with new water, otherwise the goldfish will suffocate. If the fish is found to be on the verge of suffocation and shock due to lack of oxygen, artificial rescue should be carried out immediately. The method is: hold the fish lightly with your hands, blow twice at the fish's mouth, then put it in the new water, and gently paddle the water at the fish's mouth for about five minutes. Generally, the fish can be saved. Then keep the fish in shallow water (the water depth is just the same as the fish's body height).

In short, to a certain extent, fish farming is about raising water. If the water is well maintained, the fish can also be raised well.

2. Fish feed. It is best to feed fresh fish worms or dried fish worms. Others such as rice grains, bread crumbs, steamed bread crumbs, and crab roe (soaked in boiling water before use) can all be used as goldfish feed. Feed once a day, in the morning after changing the water. Do not feed too much (feeding too much will easily make the fish eat too much and die of bloating), feed appropriately, and it is best to just eat it up. Leftover feed should not be left in the fish tank overnight, and should be cleaned up in time, otherwise it will easily cause the water to deteriorate.

3. You can raise goldfish in glass fish tanks, porcelain tanks, ceramic tanks, and cement pools. In general households, glass fish tanks are preferred because they are small and suitable for indoor placement. They are clear and transparent, making them easy to view. There are several types of glass fish tanks to choose from: (1) Round tanks. They are small in size and suitable for raising small fish of 5 to 7 cm. When water is added to the round tank, the fish appear larger and more attractive when viewed from the side due to the refraction of light. (2) Rectangular tanks. They are large in size and suitable for raising medium and large fish of more than 8 cm. (3) Wall-mounted fish tanks. They are long triangles with one side like a picture frame. They are suitable for hanging on the wall, like a moving painting. In addition, if you properly arrange some pebbles, rockery stones, and ceramic pavilions, towers, and bridges in the fish tank, and plant some aquatic plants, it will be like a beautiful moving painting, which can enhance the appreciation effect. The place where the fish tank is placed should have appropriate sunlight and good ventilation. Avoid direct sunlight in summer and allow more sunshine in winter.
