What is the most suitable temperature for colorful culture? Opinions vary. It can be said that there are 20 to 32 degrees. However, the geographical environment of wild colorful immortals is very similar. These waters are winding tributaries, and the slow-moving river banks, mangroves and a large number of decaying driftwood are the biggest features of these waters where wild colorful immortals live. Usually, the water temperature at a depth of about one meter below the water surface is about 30℃, while the water temperature at a depth of four or five meters is 23-25℃. However, this deep space is a place where wild colorful immortals live in groups. Only at night, when the water temperature gradually cools down, will wild colorful immortals swim to the surface to prey on mosquitoes and other insects.
It can be seen that the suitable temperature of wild colorful immortals is 23-28℃, with an average of 25℃. At present, it is necessary to avoid raising artificially improved varieties of Caixian in the water temperature environment of 30-32℃. Why do you say that? My experience is that high temperature and high oxygen, coupled with a large number of feeding, fish grow very fast. I did an experiment before. I raise anchovies at 3 1 degree, with 24-hour light, B 12, so that a two-month-old fish is equivalent to a three-month-old fish. But the life span of this fish may be shortened accordingly. And without high temperature and high oxygen environment, these healthy fish will die inexplicably in two to three weeks, and at this time you may still be wondering why my good fish died. (This is only one reason for dead fish) So, what is the most suitable temperature for colorful fish? In my opinion, colorful fish can grow healthily between 22 and 26 degrees. Many people may disagree with me, but the thermometer of the winner of the 200 1 Colorful Competition shows that the water temperature is 24 degrees. Can we infer that "Colorful is very sensitive to water temperature and quality. If it is not the usual temperature, the colorful state will not play so well, and it is not so easy to win the championship? " Because I raise colorful flowers in a water plant tank, 22-26 degrees is also the most suitable temperature for water plants. Looking at the temperature of the colorful champion, I am more sure that I can raise colorful flowers at 22-26 degrees.
Second, colorful food:
Food is the key to raising colorful plants and tanks. why
1, living erbium: there are a large number of pathogens and parasites. These uninvited guests will multiply and grow rapidly in the tropical environment of your aquarium after entering the aquarium. Such as hydra and algae spores, may be "smuggled" into fish tanks through live bait.
I'm afraid it's a problem to destroy them again, even high-level experts will have a headache, right So lazy people like me won't ask for trouble, so they have to stop feeding live bait.
2. Frozen food: This food form can be used as supplementary nutrition, especially those quick-frozen live bait with appropriate vitamins. However, the premise is that the treatment process of quick-frozen live bait should be reassuring, and freezing should not be interrupted or defiled in the middle. But this is exactly what many fishmongers can't do. Bacteria grow in both the freezer and freezer. The bacteria in food are mostly psychrophiles. At the low temperature of the refrigerator, it will only be suppressed and will not be killed. It just grows slowly. Studies have proved that psychrophilic bacteria will grow rapidly in a suitable low temperature environment. For example; A kind of Yersinia will not be inhibited in the low temperature environment of refrigerator, but its pathogenicity will be obviously enhanced in the low temperature environment. When a certain amount of Yersinia is ingested, it can cause disease. Yersinia can cause gastrointestinal diseases such as diarrhea, which is more serious than common enteritis and diarrhea. So freezing hamburgers and blood bugs is dangerous. Especially foods that have been stored for a long time and are eaten directly. I gave up for safety, too
3. Hamburgers: Many friends like to feed their own elaborate fresh and colorful hamburgers, thinking that this can increase nutrition and help the growth needs of colorful immortals, and they can also add various vitamins and nutrients at will when making hamburgers. Indeed, hamburgers have many advantages, but they also have some disadvantages that can't be ignored-they are not suitable for long-term storage, and the high nutritional content is easy to corrupt the water quality. In addition, the latest data points out that hamburgers also have great side effects on colorful bodies. These three points are fatal to Hamburg, and the consequences are extremely serious. Therefore, when raising colorful, everyone should choose the right food according to their actual situation. If you are feeding colorful in large quantities. To save costs, it's not bad. I think at least hamburgers are much better than live bait and frozen blood worms.
The best feed is of course artificial dry feed. I won't say more about the benefits. There are several kinds of artificial feed at present.
(1) pellet feed: it is beneficial to colorful eating, one at a time, and will not come loose. Disadvantages: it is easy to disperse in the bottom sand of the aquatic plant tank. Solution: I use a submersible pump, and an area of 8*8 cm square is isolated around the submersible pump as the feeding area, so that 80% of the pellet feed will fall in this place, which can solve this problem initially. The second method: when feeding, insert a tube into the water and pour the feed out of the tube, which can solve all the problems.
(2) Sheet-fed: the structure is more compact and the unit weight is higher. The structure is stable in water, and it is not easy to disintegrate, but it will slightly expand and soften after soaking in water, but it still maintains its original shape. It can float on the water and is not easy to melt. It softens when it meets water and is suitable for eating colorful food. Even if you sink into the water, colorful food can be easily eaten. I think it is more suitable for aquatic plants tanks than granular feed.
(3) Medicinal feed: It can expel parasites in the body, and can be fed for two days every month to achieve the effect of expelling parasites in the body.
(4) Color-enhancing feed: I like the true colors of seven colors. Colored colors always look uncomfortable, so I don't need them.
(5) High-quality artificial bait can completely replace live bait. Compared with the wild state, the ornamental fish fed with artificial bait has brighter body color, longer life span and normal reproduction. It should be noted that artificial bait can only be specially made for ornamental fish, and the feed for pond culture must not be used because of its low price! Feeding fast-growing feed can make edible fish gain weight quickly and reach the market standard in a short time. I once read a report that it takes two years for carp in nature to grow to 3 kg, but now the feed can reach the standard in 4-5 months. There is also an important substance in colorful farming, that is, gravel chips. When wild fish eat animals and plants, they will more or less bring in some stone chips or sand grains. Although these things have no nutrition at all, they are very helpful to the digestive process. Dr. geissler said in the relevant article of Aquarium Today1No.4, 998 that fish should have a "natural diet" period.
(6) As for colorful, how many times a day? This is a controversial issue. The way we raise colorful now comes from others, and we often don't know whether it is right or wrong. Here, I think what a colorful elder said is very reasonable (because through my personal practice in the past two years, many of his theories are indeed correct). So I call him "the elder". "Raising colorful people is not afraid of no one teaching, and they are afraid to teach too many people. How can I put it? The concept of fish farming is universal, but the practice is quite different. The result of hearsay usually confuses your own pace. My suggestion is: find a trustworthy person and study his skills well. The most important thing about raising colorful fish is that whenever you encounter a problem, someone can tell you the answer "correctly and definitely". Once a concept is wrong, it may not be easy to correct it. But some friends who have a good level of fish farming are afraid because. The best colorful cultivation I have taught is the white paper that I have never raised before, from which we can understand that the cultivation of thought is very important. " . People who have raised colorful immortals should think that when colorful immortals feed hamburgers, it is much more difficult to treat and filter the water quality, because only people with comprehensive judgment and experience can do things well. I believe that most of us amateur colorful lovers still can't reach this level. Because I have no place to raise water and I can't change a lot of water every day, I don't feed hamburgers. I think everyone has different conditions and different feeding methods. For example, feed more brightly colored fish, have several fish tanks to keep water, or have advanced water filtering equipment, and you can change water in time after feeding, no matter how many times you feed it. Why, you don't have to think about water. Friends with fewer fish tanks are not necessarily suitable, are they? The result of eating less and feeding more often leads to short water lifting time and can't provide colorful and good water quality, which is very important for friends with insufficient water lifting tank capacity. So I think fish farming is really a science, and we must not look at the problem separately. It is absolutely impossible to look at the surface without looking at it. ) I feed a meal a day, and many friends will question whether feeding a meal is colorful enough. The answer is yes. After two years of practice, I can definitely say "yes". I found that after feeding once a day, Qicai was still defecating after 36 hours. In other words, Qicai takes 36 hours to fully digest food. Moreover, in the waters where wild colorful immortals live, the water temperature at a depth of about one meter below the water surface is usually around 30℃, while the water temperature at a depth of four or five meters is 23-25℃. However, this deep space is a place where wild colorful immortals live and swim. Only at night, when the water temperature gradually cools down, will wild colorful immortals swim to the surface to prey on mosquitoes and other insects. This shows that Qicai eats one meal a day in the wild environment. Eating one meal a day can give the fish tank enough time to raise water. For colorful, I am used to eating only one meal a day, so I will naturally grasp the feeding time better every day. I can't go home at noon and have no time in the morning. Besides, I also found that Qicai was not used to it when I first turned on the light in the morning. When Qicai gets used to the light, I should go. It is difficult to have regular feeding except for getting off work at regular intervals. Therefore, in a specific environment, a unique feeding method has been adopted and satisfactory results have been achieved.
(7) Solution of food residue: The habit of aquatic plants feeding dry feed in tanks and eating colorful food has caused headaches of food residue. I mainly rely on polyculture to solve it. In recent years, I have mixed many kinds of fish. It gives me the feeling that lamprey is most suitable for mixed culture with colorful fish. Many friends will think that seven people will treat bottled fish as snacks. In fact, this phenomenon exists, but there is no need to worry. Friends can easily find such a phenomenon that when new fish are put into the original fish tank, they are always chased by other fish. I also found this problem when I put the bottle fish into the fish tank again. In the first 20 minutes, Qicai will think it's food, and run after the bottle fish crazily. After 30 minutes, they can live in peace. As long as you are full of colorful food, you generally don't eat bottled fish. The solution is also simple. At the same time, put some feed into the tank. Colorful is busy eating, and the problem is solved without caring about these new friends.
