At the end of this year, wandering on the street, I suddenly found that there were paradise fish sold on the street, and it was as high as 25 yuan a piece, which made me fall into a deep thought. At that time, I was bored in my hometown, so I suddenly remembered the interesting things of my childhood, so I led my daughter to a small ditch in the field, blocked the drainage, and pounded it up, but the result was nothing, asked the surrounding old people, reflecting that I had not seen his figure for a long time, and today I saw it on the street and had become a profit tool in the eyes of businessmen.
<h1>The main points of this article:</h1>
Isn't it a freshwater fish species that is more common in the eyes of the post-70s and post-80s generations? According to childhood memories, at that time, the fighting fish were big rivers and small ditches all over our country, but why is it difficult to see its figure now? I vaguely remember that since I entered the society, I have never seen it again in the wilderness of my hometown. Now our children can only see it through pictures and street shops. And we can no longer experience that in the past, we can intercept small ditches and drain the water to harvest a lot of fish, which is our regret and worthy of our deep consideration. So where are such beautiful paradise fish mainly distributed in our country?

<h1>The habits of the heavenly fish</h1>
(1) The growth environment of paradise fish: paradise fish has low requirements for water quality, and the pH of water is suitable for neutral water level. The water temperature is between 24-27, which is the most suitable for its growth, and the cold tolerance is very strong, it is a low-temperature low-oxygen fish, and usually inhabits slow-flowing or still-water environments such as streams, ponds, farmland, and ditches.
(2) Food of paradise fish: Paradise fish mainly feed on zooplankton, insect larvae, and also eat filamentous algae.
(3) The breeding method of paradise fish: When the paradise fish reaches the breeding period, the male fish will begin to nest, and air is their best material. Strictly speaking, it is to build a nest with bubbles. When the male paradise fish reaches the breeding season, it will use the mucus in its mouth to cover the air inhaled from the surface of the water to produce bubbles, and then spit it out of its mouth to build a nest. The bubbles of paradise fish wrapped in mucus can easily adhere to each other even if they are not easy to break. The nest of the paradise fish consists of dozens of bubbles, generally about 10 centimeters in diameter. Paradise eggs hatch within a day or two. When the male has built a nest, the male will become more and more colorful, and in order to attract the female, he will dance and spread the large tail fin. Gleefully swim around the female and lay eggs.
(4) Lifespan of paradise fish: In the right environment, the lifespan of female paradise fish is generally 2-3 years, while males are longer than females, generally 3-5 years.
(5) The special function of paradise fish: Paradise fish is different from other fish, it has auxiliary respiratory organs, can directly use air for internal exchange, even when away from the water can also survive for a long time.
Summary: Through the above description, we can see that the paradise fish is really a kind of fish that everyone loves, and it may be because of its beauty that it is loved by everyone.
Fighting fish is not only deeply loved by the masses in China, but also enjoys a high reputation in Western countries, especially Germany. Frank, a famous German expert on ornamental fish. Frank Schafer's book All Labyrinths (1997) describes The Paradise Fish in China: "The earliest tropical ornamental fish and one of the most beautiful species to date." ”
<h1>Why paradise fish is so popular in Western countries</h1>
(1) The nature of the paradise fish: the paradise fish is aggressive by nature, and it is precisely because of this aggressiveness that it is favored by many Western countries and treated as a pet, in their view, because the paradise fish is aggressive, the meaning is that the work is aggressive, the ups and downs of the business field, the competition, can survive are fine. When the heavenly fish fight with each other, the collision of talent and strength shown, and the competition of strength and strength can effectively promote people's fighting spirit.
(2) The beautiful appearance of paradise fish: the gorgeous appearance of paradise fish, as well as sexy fins, especially male paradise fish, when it opens the fins, people will be deeply attracted to it.
To sum up: it is not unreasonable why paradise fish is loved by Western countries, as Frank. As Schaefer says, "The Heavenly Fish is by far one of the most beautiful species."
The water quality requirements are not high, and the cold resistance is low and low oxygen, why is it more and more difficult to find its existence now? This requires us to think carefully and find the reason. therefore:
<h1>Why is it becoming more and more difficult to see the paradise fish in our country? </h1>
A fish does not become less and less for no reason, and the same is true of the paradise fish, which needs to be analyzed and discussed, and I will explain my point of view below.
(1) Man-made fishing: At present, the main reasons for the more serious water ecology in China are some electricity, poison and nets, so with the rapid development of science and technology, paradise fish are facing danger all the time, which is also one of the reasons why it has developed rapidly in just a few decades and is difficult to see.
(2) Many natural enemies: Due to the small size of fighting fish, in the wild environment of the weak and the strong, it is not only necessary to deal with many "natural enemies", but also to suffer from people's fishing. So this is one of the reasons why there are fewer and fewer.
(3) Pesticide pollution: With the development of society, the fields now cultivated are all used with pesticides and fertilizers, and the negative impact is that paradise fish cannot survive under such a water body.
To sum up: in the natural wild environment, the paradise fish not only faces the threat of natural enemies, but also is ruthlessly destroyed by electricity, poison, and nets, coupled with changes in the environment in recent years, so that it is becoming more and more difficult to see. These objective and subjective reasons all compress its living space.

<h1>Finally, summarize and summarize:</h1>
For Western countries, I hope that they can continue to love the paradise fish, because this is indeed a very rare and valuable fish, whether it is a pet or a part of natural resources, it has its own reason.
For our country, we hope to crack down on some lawless elements of electricity, network, and poison in a strict and serious manner, and use practical and feasible methods to restrain them, so that our natural ecology will get better and better.
For us: it was once a memory of our childhood, and every time we see it, we can think of the bits and pieces of our childhood, and hope that our ecology will get better and better.
Finally, I once again appeal to the majority of fishing enthusiasts to do it: stay big and let go of the small, and people will go to the field clearly.
