【Foreword】 Fortune catfish, scientific name redtail catfish. Native to the Amazon River Basin, it prefers weak acidic soft water and has a fierce temperament. Because of its unique body color and eyes, it is known by aquarists as a catfish.
Fortune catfish, scientific name redtail catfish.
Zhao Cai cats are not picky eaters, basically eat everything, so many people think that Zhao Cai cats are very good to raise, at least think that they are not so tired to raise. Indeed, the Zhao Cai cat is better to raise than other ornamental fish that are also native to the Amazon Basin. Like colorful angelfish, dragon fish, etc., the difficulty of raising is relatively large, the water quality is slightly wrong, or there is a slight omission in feeding, it may be lost, or there will be disease problems such as eye loss. In short, for novices, it is indeed not difficult to raise a fortune cat.
It is relatively difficult to raise cats, but it is not without difficulty. Want to raise a good cat, the first point is to take care of the temper of the cat, this fish is very fierce, as long as it is smaller than its fish will chase bite, so the fish tank to avoid polyculture than its size of other fish, otherwise the tank can not be peaceful.
Another point is to keep the water quality clean, no matter how tenacious the vitality of the cat is, there are also requirements for the living environment. If you are a lazy fishing novice who is unwilling to take care of the fish tank for a long time, the fortune cat will also be raised by you.
What do I need to pay attention to when raising a fortune cat? Here are some of my experiences and advice:
<h1 class= "pgc-h-arrow-right" >, water quality is closely related to bait, and the purchase of bait is exquisite. </h1>
Some novices are reluctant to bother cleaning the water tank, and when buying bait, they specifically focus on those who do not have grease, thinking that this kind of bait is not easy to damage the water quality, and it is very easy to raise fish, which is wrong.
Fish farming must be adequately nutritious, the bait is rich in protein, and there will be significant oil. When the bait is processed, the grease is not directly mixed into the bait, because it is difficult to form the bait that way. Usually, after the bait is made and formed, it is sprayed with grease on the outer layer, and once this kind of bait enters the water, it is naturally easy to pollute the water quality.
It needs to be clear, but all the legitimate fish baits are greasy. The bait is rich in nutrients, so that the fish can grow healthily. As for the water quality is easy to be turbid, that is the problem of the amount of fish you feed, of course, some of the feed oil and muddy water is also a weight that fish farming must bear.
<h1 class= "pgc-h-arrow-right" > second, when changing the water in the fish tank, pay attention to the change of temperature. </h1>
The suitable water temperature for the growth of Zhaocai cat is 22 ° C ~ 28 ° C, because the amount of food for Zhao Cai cat is large, the "displacement" is also large, and the water temperature is high, the water quality is easy to deteriorate, and it needs to be replaced in time. In the water change is exquisite, can not blindly change, one time can not change too much, to a small number of times, the amount of each water change is best not more than twenty percent, the reason for this is because a large number of water changes are difficult to ensure the water temperature and pH constant.
Even if the cat with tenacious vitality changes sharply, or the pH changes greatly, it will get sick or even die. According to experience, the temperature difference between each water change is best not to exceed 2 ° C, otherwise the probability of fish getting sick will increase significantly.
Special care is that in winter, the weather is relatively cold, and when changing water, it is necessary to use a heating rod in advance to heat in the trapped water tank, which should be consistent with the temperature of the original water tank.
Some people are reluctant to change the water frequently, and the method taken is to grow aquatic plants and various algae in the fish tank, hoping to absorb the nitrate in the water with the help of these things, so as to achieve the purpose of cleaning the water quality. This method has a certain effect, but it is very limited, and it has a very limited effect on raising large fish such as Zhao Cai Cat or if you raise fish with high density.
<h1 class="pgc-h-arrow-right" > third, the pH should be consistent when changing the water in the fish tank. </h1>
The pH in the fish tank should also pay attention to maintaining consistency, adjusting the pH can be used with chemical preparations, but beginners are not easy to master, in fact, the best way is to use natural items, the most common are sunken wood, olive kernel leaves, coral bones, pineapple skin and so on.
Such items are naturally occurring in nature and are rich in a variety of substances that can effectively adjust the pH. Not only that, but it can also cultivate nitrifying bacteria and decorate the environment of the fish tank, which is a natural set material. When adjusting the pH, always pay attention to monitoring, the slightest mistake may lead to the fish getting sick.
Adjusting the pH with natural items, the advantages are obvious, not easy to problem, but the disadvantages are also obvious, that is, the effect is relatively slow. To quickly adjust the pH, you need to use chemicals, such as baking soda. Baking soda is sodium bicarbonate, commonly known as edible alkali, which can quickly increase pH. When in use, an appropriate amount of baking soda can be melted into water, and then the part that is not dissolved in water is thrown away, and the solution is dissolved into water several times.
The use of baking soda to improve pH should pay attention to the value of monitoring pH at all times, it is best to have certain chemical knowledge, you can calculate the number of baking soda required according to the amount of water in the fish tank and the pH standard. A small spoonful may exceed the pH.
<h1 class= "pgc-h-arrow-right" > fourth, the cleaning of the filtration system is the basic guarantee of water quality and health. </h1>
The key to raising catfish is to raise water, the key to raising water is filtration, to set up a good filtration system, regular cleaning. The commonly used first-level filtration, mostly filter cotton, is mainly used to filter fish food residues and excrement, such filtration is required to be cleaned in time.
Cleaning filter cotton requires exquisite methods, can not believe in vigorous miracles, and needs to be carefully rubbed. After cleaning, do not put it back directly, but also need to soak in the original tank of water to keep the microorganisms in the water able to adhere to the filter cotton. In addition, if the filter cotton is long, it will appear black, mostly attached to the oil, which can be removed with edible alkali.
In order to maximize the stability of the water environment, it is best to put a few more filter cotton at a time, so that only the top layer needs to be cleaned when cleaning, and the filter cotton below can be changed once a few months.
As for the indispensable biochemical cotton in the fish tank, it is easy not to clean and replace, because the main role of biochemical cotton is not to filter the residue, but to cultivate nitrifying bacteria. The main role of nitrifying bacteria is to remove harmful substances such as nitrites from fish tanks, which is the most important guarantee for the health of fish.
<h1 class= "pgc-h-arrow-right" > five, the purchase of filtration system to be rational, the most important thing is the filter effect. </h1>
For newbies, be cautious when buying a filtration system on the market and don't be fooled by the fancy shapes. The main purpose of filtration is to purify water quality, no matter how high-end the filtration system, its purpose is the same.
For example, the bottom filter system, the so-called bottom filter, is to set up several filter layers, the filter layer is separated by glass, and then put the filter media, the water through a filter layer, the harmful substances are filtered out, and the water is pumped back to the fish tank through the pump, which completes a complete filtration, and does not require more complex design.
Another example is the filtration system, which is nothing more than putting the filter media in the box, and then pumping water through these filter materials, and the water returns to the fish tank, which is such a filtration process, which is not complicated at all. There are many layers of styles on the market, and the filtering effect may not be very good. When buying a filtration system, don't be fooled by these tricks, but look at the actual effect.
The most important thing in the filtration system is that the filter tank should be large enough, which is the root of the filtration system, only if the filter tank is large enough, can enough filter media be placed, and the effect of filtration is basically guaranteed. In addition, the filter tank is large enough to cultivate enough nitrifying bacteria to effectively dispose of harmful substances in the water.
At the same time, the filtration system with a large enough filter tank is a good buffer belt, the amount of water storage is large, and the water quality in the fish tank will not change drastically, so as to maximize the health of the fish.
<h1 class="pgc-h-arrow-right" > summary:</h1>
We need to pay more attention to raising a good cat, the fish tank should be large enough to ensure the amount of dissolved oxygen and the necessary activity space for the cat, and it is best to place the fish tank in a ventilated position. To ensure the stability of water quality, we need to replace it regularly, and we cannot have laziness and luck, perhaps because the water change is a day late, and the cat will have a problem.
All in all, the very good cat fish also needs us to raise carefully and carefully, so that the cat can really attract wealth into the treasure.
