Friends who have just started raising ornamental fish have this experience. Buy back the fish and put it in the fish tank. Everything was fine in the first few days. After a few days, I saw that the water was muddy and the fish had faded. I didn't know the fish was sick until I asked. "What? Will fish get sick? " With a grain of salt, I invited a doctor and gave medicine. My wallet hurts badly. I spent a lot of time, and my hair may turn white. Finally, every fish saw Lao Mao. Bite your teeth and buy more. For a few days, I got sick again, cured again, died again, bought again, and went on and on. Unconsciously fall into a strange circle. Finally, there is a feeling that fish farmers who can't cure fish are not good fish farmers. Ha ha. Think about it. Am I wrong?
This is a beginner's problem. Everyone will commit a crime. Not surprising. It is strange that some people can't extricate themselves. Caught in the strange circle of Dr. Fish and couldn't get out. It is believed that raising fish is to constantly treat the arc.
In fact, raising fish is the same as raising children. The important thing is not to treat them, but how to prevent them from getting sick. That is, to prevent diseases. There will be small defects in the way of recovery of sick fish, which will reduce its ornamental value. Besides, your favorite fish always greets you sick, and I don't think your mood will be better. Right?
So how can we keep the fish from getting sick? The most important thing is to raise water. In other words, maintain the hydrological environment in the aquarium. At least let the fish, beneficial microorganisms, harmful microorganisms, nutrients and harmful compounds in your aquarium reach a certain balance. If it is an aquatic plant box, the role of aquatic plants in the hydrological environment should be added.
Harmful microorganisms in the aquarium mainly refer to pathogens such as viruses and bacteria. Harmful compounds are various inorganic salts produced in water, such as phosphate and nitrite, which will do harm to fish. In addition, feed live bait to friends who admire fish (such as water lice, filariasis, blood worms, etc.). ) long-term capture from nature will inadvertently bring in some organisms and pathogens (such as fish lice, cat head lice, viruses, etc. ) is basically the main cause of diseases of ornamental fish cultured in aquariums.
Compared with rivers and lakes in nature, aquariums are much smaller and more isolated. The high fluidity of water in nature makes all kinds of harmful salts there quickly washed away by the current, and a large number of elements in natural water will also neutralize some harmful salts. The wide water body in nature also makes this fish have a wide range of activities. In order to survive, they have to run around for food and avoid predators. The chances of infection and invasion by pests will be much smaller. Then, in view of these points, we can make a plan to prevent diseases.
First of all, there should be fewer big fish in the fish tank. That is to say, the density of fish farming should be relatively small, and 1cm fish should be raised per liter of water. This breeding density is the experience summed up by many predecessors. You can lower the density a little.
Second, the arrangement of filters. Some friends will only buy an air pump when they start raising fish. If you think the water is short of oxygen, pump it up. If it is turbid, change it. It doesn't matter whether you buy a filter or not. This idea is very dangerous. As we said in the colorful article on captive equipment, the filtration device in the present sense refers to biochemical filtration. It is no longer simply removing impurities from water. It is a method to establish a good circulation system and improve the hydrological environment by eliminating harmful substances in water through microorganisms. This is a system that must be prepared. In my experience, the gap between filter channels should be bigger and longer. The impurities are filtered by coarse cotton filter for the first time, and then filtered by nitrifying bacteria attachment groups such as biochemical cotton filter, biochemical ball or ceramic ring, so that nitrifying bacteria attached to it can play a role. Then the harmful elements such as chlorine and cadmium are removed by activated carbon filtration. Finally, filter it with a cotton filter and put it back in the aquarium. This kind of filtration is my experience in raising fish. Because, in order to save money, I usually don't use the finished filter screen, but set up my own filtering device. This will be much cheaper.
Third, the speed of water flow is higher. It depends on the kind of fish. You raise fish in warm water or even still water. You can't wash it with big water, can you This means that the circulating water flow is as large as possible on the water flow it can bear. To simulate natural water flow.
Fourth, lazy people can't raise fish. Fish farmers must develop good habits and monitor and check the water quality and the living conditions of fish every day. This job is boring. But you have to do this. Carefully check the hydrological indexes such as pH value and nitrite content of water. Observe the body of the fish. The shape and movement of fish ... >>
Question 2: How to raise family ornamental fish is to raise water. If the water is well raised, it is difficult for fish to die. You have to learn how to raise water first, and Baidu will find it! As long as the water is well raised, the fish will be healthy. Many people say that fish is difficult to raise and too delicate. In fact, it is simply wrong. If you don't create a good living environment for fish, even the strongest fish will die, just like throwing people into a poisonous room. No matter how powerful the people are!
Question 3: How do ornamental fish raise water? Let the water dry for 2 ~ 3 days, then open the filter and add nitrifying bacteria. Of course, if you can get valves such as filter cotton and biochemical cotton from someone else's fish tank, put some fish in it and remember to feed them every day. It takes about a week to get the water.
Question 4: How to raise ornamental fish? Without grass, the water quality is not easy to control, and it will soon become dirty. You can measure it yourself. Many people are just too lazy to raise grass, and the lack of experience in fish farming leads to dead fish, which is very hard. . . .
First of all, aquatic plants absorb carbon dioxide and release oxygen through photosynthesis, so fish farming does not need to increase oxygen, and indoor oxygen can be increased.
Secondly, fish waste and food residue are the source of water pollution, and how to deal with these organic matters is the most important problem. Although these nitrogen-containing organic compounds are toxic, they will be decomposed by nitrifying bacteria through nitrification, and some undecomposed and decomposed products will remain in water. At this time, aquatic plants can play an unparalleled role-absorb these substances and transform them into their own nutrition, and the redundant elements and heavy metal ions in natural water will be filtered out.
Never complain that fish die easily. It's just that people put fish into empty tanks from the natural environment. Water is still tap water, with chlorine and heavy metals. How do they adapt? Aquaculture is to simulate the natural ecological environment!
It is suggested that Baidu visit Qingsen Aquarium and learn the same experience of fish farming.
Question 5: How to raise fish 1. Feeding: All fish are fed nutritious animal feed and white sesame seeds. Animal feed, such as Daphnia, earthworm, Tenebrio molitor, caterpillar, dust mite, etc. The main feed is earthworm and white sesame. Both red earthworms and black earthworms can be fed. You can feed raw white sesame seeds. White sesame seeds are easy to buy. Goldfish love to eat, easy to digest, and not easy to pollute the water. Don't feed inferior goldfish feed. Because this kind of feed has too much starch, poor nutrition, difficult digestion and easy pollution of water quality, goldfish will grow slowly and get sick easily after eating malnutrition. Goldfish will not die as long as they eat digestible food. When to feed, usually once a day in the morning and evening, it is not advisable to feed more until it is eaten up. Otherwise it will pollute the water body.
2, lighting: it is best to put the fish tank in a sunny place 1-2 hours. In this way, ultraviolet rays in sunlight are used for sterilization. Play a role in preventing diseases. This can reduce diseases. Try to prevent fish diseases, supplemented by drug treatment. At the same time, due to photosynthesis, the color of fish is more bright and beautiful.
3. Change water: Changing water frequently can increase dissolved oxygen in water. When changing water, you can only change one-third to one-quarter, and you can't change a lot at once. The fish can't adapt. It is very important to keep the water quality of the aquarium clear. There is enough dissolved oxygen in the water to make fish grow and grow fast. Otherwise it will stop growing or even die. When to change the water is inconclusive, but it depends on the water quality. If the water quality is turbid, change it more or less.
4. Stocking density: rectangular aquariums in China are not suitable for raising more, but it is not suitable for raising less. For example, in a container with a length of 40 cm, a width of 25 cm and a height of 30 cm, you can raise 6 to 8 small goldfish with a length of 5 to 7 cm. For example, a round glass jar with a diameter of 26 cm and a height of 13 cm can raise 4 ~ 6 small goldfish with a diameter of 4 ~ 6 cm. Adult fish with a body length of more than 8 cm should not be kept in small glass tanks, but in large glass tanks or ceramic tanks, and equipped with small oxygenators for standby to prevent hypoxia. These stocking densities are only reference figures, but also depend on the level of water temperature, the strength of fish and the quality of water, which cannot be determined mechanically. Generally speaking, there are large fish and few animals. Raise more in winter and less in summer; You can raise more when the water temperature is low, and raise less when the water temperature is high. Domestic goldfish, if you master the above points, will certainly make goldfish healthy and lively, colorful, swimming around in the water, loved by people, so that you can never get tired of watching it and have fun. I'm sure I can raise it. I wish you success!
Question 6: The water temperature of ornamental fish is at least 26 degrees or 28 degrees.
This kind of fish is quiet. Don't mix with other powerful fish.
The requirements for water are relatively high. Acidic soft water
Its feed can be red worms, swallows (mosquito larvae) and blood worms, but in order to raise colorful fish with good shape and color, it is best to freeze hamburgers.
Colorful angelfish has a small stomach, which is most suitable for eating less and more meals, 3 to 5 times a day. Choose a fixed time every day and feed regularly and quantitatively. Only in this way, Qicai will grow faster and have a better figure. Don't feed too much bait at a time. Generally, after eating it within 5 minutes, the fish can eat 60% to 70% full. After feeding the bait, the remaining bait should be pulled out in time to avoid affecting the water quality.
The nutritional value of red worms is average, and the fish lice are too small to eat colorful food.
The frozen "hamburger" is specially made for colorful, and the main component is beef heart, and the fat, blood vessels, skin, shrimp, chicken and fish should be completely removed. , and add a proper amount of vegetables (spinach, celery, tomatoes, carrots), carrots are cooked, then add some yeast and vitamins A, D, E, chop them up, stir them with a meat grinder, and freeze them into small pieces in the refrigerator. It should be noted that additives in colored feed account for 25%. Additives contribute to digestion and absorption, and also contribute to bright colors.
Question 7: How to raise ornamental fish with seawater at home? At present, there is sea salt specialized in raising marine fish. You can buy a generation of sea salt and match it according to the product instructions.
Question 8: Why did my ornamental fish die after a short time? Keep goldfish at home, and put the glass jar in a ventilated, sunny place near the window. Attention should be paid to stocking density and reasonable arrangement should be made according to the size of containers. It is better to raise more than less. Because the indoor air circulation is not good, raising more water is easy to be turbid, which can easily lead to goldfish dying of lack of oxygen. If you have a pump, you can raise more. If the goldfish is found to have a floating head, it is necessary to turn on the air pump for oxygenation, especially at night.
Live fish worms are the most ideal bait for family fish farming, and the water quality is not easy to deteriorate. Dried fish worms and synthetic pellet feed can also be used. There are live fish and worms on the market now, but it is also very troublesome to buy them every day. For dried fish worms sold in the market, choose fresh and loose particles to feed the fish, and don't buy old and moldy dried fish worms to feed them. It is best to use full-price feed with complete nutrients for artificial pellet feed, which is sold in the market.
In order to keep the water pure, the feeding amount should be strictly timed and quantified. Usually, it is advisable to feed 1 2 times a day, and each feeding amount should be eaten within half an hour. Don't feed too much bait. Feeding too much has two disadvantages: first, the fish is full, the metabolic level is improved, and the oxygen consumption is increased, which is easy to cause goldfish to die of hypoxia and suffocation; Second, the bait is left, which is easy to rot and ferment, making the water quality worse and causing hypoxia. In fact, goldfish are hungry, and there will be no problem if they are not fed for a week or two.
It is very important to keep goldfish clean. It is necessary to suck off the accumulated slag with latex tube regularly, clean up the feces and residual bait at the bottom of the glass jar together with turbid water, and then slowly replenish the fresh water that has been left for one day. If water plants are found floating or rockeries are knocked down during operation, they should be restored to their original state in time.
The longer the fish is raised, the more sediment will be deposited. Although it is removed every day, it cannot be completely removed. If the sediment increases and affects the clarity of the glass jar, it is necessary to completely change the water to clean the glass jar, so as to keep the water pure and easy to watch, and also to maintain a good living environment for goldfish.
Rectangular glass jars used by ordinary families are small in size, so it is not advisable to store more, and less should not be more. For example, in a container with a length of 40 cm, a width of 25 cm and a height of 30 cm, six to eight goldfish with a length of 5 cm to 7 cm can be raised. Adult fish with a body length of more than 8 cm should not be kept in small glass tanks, but in luxurious large glass tanks or ceramic tanks, and equipped with small oxygenators for standby to prevent hypoxia. The above stocking density is for reference only, but also depends on water temperature, fish size and water quality. This cannot be done mechanically. Generally speaking, if the fish is big, it is necessary to raise less; You can raise more in winter and less in summer; You can raise more when the water temperature is low, and raise less when the water temperature is high.
