Why can't marine ornamental fish catch fire in China?

For people who have never raised fish before, it is not clear that ornamental fish can only be bought nearby. If there are no local fish, they can buy them in the nearest big city. And online shopping. The survival rate is low in hot weather, so novices are not recommended. Popular species are basically only suitable for advanced players. Beginners should start with cheap varieties, such as guppies, betta, tiger skin fish and zebra fish. Ornamental fish refer to those fish with bright colors or strange shapes and ornamental value. They are distributed all over the world, with more than a thousand species. Some of them live in fresh water, some in seawater, some from temperate regions and some from tropical regions. Some of them are famous for their brilliant colors, some for their strange shapes, and some for their rarity. In the world ornamental fish market, there are usually three strains, namely temperate freshwater ornamental fish, tropical freshwater ornamental fish and tropical seawater ornamental fish.

Ornamental fish in the world ornamental fish market, they usually consist of three categories, namely temperate freshwater ornamental fish, tropical freshwater ornamental fish and tropical seawater ornamental fish.

(a) temperate freshwater ornamental fish

The freshwater ornamental fishes in temperate zone mainly include red crucian carp, China goldfish and japanese koi, mainly from China and Japanese. The appearance of red crucian carp is similar to that of edible crucian carp, and it can be divided into red crucian carp, red and white crucian carp and five-flowered crucian carp according to different body colors. They are mainly kept in the fountains of lakes or tourist attractions, such as "Jiuqu Bridge" in Shanghai Old Town God Temple and "Huagang Fish Watching" in Hangzhou.

The ancestor of China goldfish is the wild red crucian carp hundreds of years ago, which was first seen in the releasing pond in Jiaxing, Zhejiang Province in the early Northern Song Dynasty. 1 163, Emperor Zhao Gou of the Southern Song Dynasty raised a large number of golden crucian carp in the palace. Family-raised goldfish spread from the palace to the people and gradually spread. The domestication of goldfish has gone through two stages: pond culture and pot culture. After careful selection by several generations of folk artists, the single-tailed goldfish gradually developed into two-tailed, three-tailed and four-tailed goldfish, and the color gradually changed from a single red to red and white, five flowers, black, blue and purple. Its shape has also changed from a long and narrow spindle to an oval and spherical shape, and its variety has changed from a single golden crucian carp to today's rich and colorful. According to historical records, China goldfish was first introduced to Japan in the Ming Dynasty, and it was introduced to Japan again in 16 15- 1623. Japanese koi's original species is red carp, which was introduced to Japan from China in the early days. After careful cultivation by the Japanese people, it has gradually become one of the world-famous ornamental fish. The main varieties in japanese koi are red and white, Showa tricolor, Dazheng tricolor and Qiu Cui.

(2) Tropical freshwater ornamental fish

Tropical freshwater ornamental fish mainly come from rivers and lakes in tropical and subtropical regions. They are widely distributed, with a wide variety, different sizes, different physical characteristics, colorful and very beautiful. According to the different origin, it mainly comes from three regions: first, many countries and regions in the Amazon basin of South America, such as Colombia, Paraguay, Guyana, Brazil, Argentina, Mexico and other places; Second, many countries and regions in Southeast Asia, such as Thailand, Malaysia, India, Sri Lanka and other places; The third is the three major lakes in Africa, namely, Lake Malawi, Lake Victoria and Lake Tanganyika.

There are three kinds of famous tropical freshwater ornamental fish. First, the variety of lights, such as traffic lights, taillights, blue triangle, red lotus lights, black lotus lights and so on. , small and exquisite, beautiful, looming, very popular. The second is the angelfish series, such as red colorful, blue colorful, striped blue-green colorful, black fairy, sesame fairy, Yuanyang fairy, red-eyed diamond fairy and so on. , are elegant, gentle and elegant, very beautiful. Three, arowana series, such as silver dragon, red dragon, golden dragon, black dragon fish, etc., are known as "living fossils", precious and beautiful, and popular.

(3) tropical marine ornamental fish

Tropical marine ornamental fish are composed of more than 30 families. The common species are Sparidae, Papilionidae, Echinopteridae, Sparidae and so on. Its famous species are Queen Fairy, Queen Fairy, Emperor Fairy, Moon Butterfly, Moon Eyebrow Butterfly, Herringbone Butterfly, Hippocampus, Red Clown, Blue Devil and so on. Ornamental fish in tropical seawater are particularly bright in color and rich in body patterns. Many varieties have the nature of self-protection, some have artificial eyes on the body surface, some have sharp blades on the tail handle, some have hard and poisonous thorns, some can secrete poisonous juice in the body, some can change their body color at will, and some are good at imitating, which fully shows the magical charm of nature.

Watching and breeding ornamental fish is a very interesting leisure activity for human beings today. It can let us appreciate the wonders of the underwater aquarium world, some like lakes and mountains, some like Shan Ye jungle, exotic flowers and plants, leafy vines, and all kinds of fish are colorful, with the help of light and shadow, dazzling and dazzling, daydreaming. Now they can be seen in many tourist attractions, shopping malls, hotels, entertainment and exhibition places. In many families, there are also various types of goldfish, angelfish, other tropical fish and seawater ornamental fish, which have become a landscape in the courtyard or hall, elegant and unique, pleasing to the eye. However, raising ornamental fish is a highly technical job, which requires the guidance of scientific methods, so that we can cope with it freely, raise the fish well and meet our own needs for viewing and entertainment.

China betta, also known as: fork-tailed betta, rabbit fish, paradise fish, etc. Longyan people call it "pengpeng" or "Class Three". In the past, it was found everywhere in wild streams, rivers and rice fields in the south of China. Because its distribution area belongs to subtropical zone, China Betta can survive well in low water temperature environment above 0℃ and grow well in water temperature above 14℃. It is a famous ornamental fish species.

There are four kinds of wild fighting fish in China:

Betta

1. fighting fish with fork tail,1758-widely distributed in South China, Taiwan Province Province and Viet Nam, commonly known as Pucha.

2. Round-tailed betta, 1842—— distributed in North China (Shanghai and the provinces north of the Yangtze River).

3. Vietnamese black fork-tailed betta, 1936—— distributed in the border of southern Vietnam and Guangxi Zhuang Autonomous Region.

4. Hong Kong black fork-tailed betta, 2002- distributed in Hong Kong, Fujian, Guangdong and eastern Guangxi.

Water supply quality

Betta is not strict about temperature. Generally, it can live in the range of 4 ~ 3 1℃, and the water temperature of 24 ~ 27℃ is the most suitable for its growth. The optimum pH value of water is neutral water, and the pH value is 6.5 ~ 7.2. It is best to keep the dissolved oxygen at 5mg/l under the condition of artificial feeding. In addition, we should also pay attention to controlling the contents of some toxins in the water, and take residual chlorine 0mg/l, nitrite 0mg/l, nitrate 5mg/l, ammonia nitrogen 0mg/l and phosphate 0mg/l as the standards to test whether the water quality of your culture meets the needs of fish, and make timely adjustments to provide a suitable water quality environment for betta fish.

Feeding and management

Because betta is a kind of ornamental fish that is relatively tolerant of rough farming, many people neglect management in the breeding process. Even if the fighting fish can survive tenaciously, it will repay you with listlessness and depression. If you want the fish to live freely and add happiness to your life, you must try your best to show the love of your master.

There are no special restrictions on the containers for raising betta fish, ranging from mixed fish tanks to glass jars. However, due to their aggressiveness, in order to avoid their fighting, other fish are generally not mixed, but some fish bigger than betta can be mixed. First of all, a clean layer of thin bottom sand or colored sand should be laid on the bottom of the fish tank, which can stabilize the roots of aquatic plants on the one hand and provide adhesion for microorganisms on the other. The ratio of water to bottom sand is 5: 1. In order to keep enough oxygen in fish tanks and provide hiding places for fish, aquatic plants with low CO2 demand, such as Ceratophyllum and Kuroshio, should be planted appropriately. In addition, in order to provide sufficient light for the photosynthesis of aquatic plants, it is best to configure a small lamp with soft light in a small glass tank.

The equipment for raising betta fish is not only light and simple, but also effortless. Just siphon the excrement and dirt at the bottom of the pool every 3 ~ 7 days with plastic hose, pump out about13 of sewage, and inject dechlorinated tap water to create a clean water environment. Because there is no power equipment to drive the water circulation in the small aquarium, it is necessary to pay attention to remove the oil film on the water surface formed by residual bait and feces at any time. You can use bamboo chopsticks to hold a piece of absorbent paper and drag it gently on the water. In addition, some beneficial microorganisms and trace elements should be added according to the water quality.

Betta is an omnivorous and carnivorous fish species, which can be fed with a variety of baits. Try not to make the recipe of Betta too monotonous. Usually, the artificially dried bait is complete in nutrients, clean and hygienic, and it is an essential bait for most people to feed betta. In order to adapt to the habits of upper-level water fighting fish, it is best to choose floating feed, if new fresh bait can be fed at intervals, such as harvest worms, dragonflies, silkworms, water fleas and so on. It can make the body color of betta fish more vivid, and at the same time, you can enjoy the fun of feeding fish. However, because most of these baits contain bacteria, it is easy for fish to get sick. They can only be used as seasoning for fighting fish. When feeding, be sure to rinse it clean, eat it within 5 minutes each time, and feed it once a day.

Matters needing attention

China betta is a very lively fish, especially adult fish. When the environment changes suddenly or is frightened, it will jump over the tank. Therefore, the environment has changed when raising, so we must pay attention to adding a cover to the fish tank to prevent the tragedy of jumping off the building.

Breeding mode

In the process of fighting against the harsh living environment, betta fish has formed its own unique way to continue its race, which is generally divided into foam nesting and oral incubation. Preparation of breeding pond: Before breeding, prepare the breeding pond in advance. The glass pond is about 30cm× 10cm× 15cm, and the bottom is covered with a layer of clean silica sand, and aquatic plants such as cow hair shake, antler moss, Mu Si and small mushrooms are densely planted. So as to provide shelter for the timid female fish in the early stage of mating. Adding aerated water into the culture pond, keeping the water temperature at 26-27℃ and the pH value at 6.8-7.

Foam nesting: There are fighting fish in Thailand, fighting fish in Gaidian, fighting fish in China and so on. Generally, betta fish is sexually mature in 4 ~ 8 months, so you can choose betta fish with a height of more than 6 cm to breed, and the female fish should choose fish with mature eggs in the abdomen, otherwise it will be violently attacked and injured by the male fish when it is put into the breeding tank. The male and female bettas bred in the nest are in estrus at the same time, and the parent fish can be put into the breeding pool at the same time. Male fish will be based on floating plants, constantly swallowing air, spitting gas from gills around phytoplankton, forming a circular foam nest. After the floating nest is built, the male fish will dance around the female fish, show their bright colors and win the favor of the female fish. Gradually, the female fish will go downstream to the newly-built bubble nest under the guidance of the male fish. They began to mate under floating nests. The male fish bends his whole body into a "U" shape and hugs the female fish tightly. Female fish lay about 400 ~ 1000 eggs at a time. The ovum to be discharged is combined with sperm, and the female fish can be taken out after the fertilized egg slowly floats to the surface of the water, so as to prevent the male fish from pecking the female fish and causing injury or even death. The male fish will put the eggs floating in the water in his mouth and send them back to the nest one by one, so that the eggs can be stacked together and float on the water like a hill. At this time, they will change their usual domineering and begin to take care of fish eggs patiently and meticulously, not only to constantly repair floating nests, but also to stir the water surface with fins to provide enough oxygen for eggs and constantly identify and eliminate dead fertilized eggs. After 48 hours, the small fish hatched from the egg and dragged its tail tip under the foam to float on the water. At this time, the young fish survive by absorbing the yolk sac, while the male fish will always guard the young fish and bring the young fish back to the foam with his mouth until the yolk sac is absorbed and the young fish swims independently three days later, before the male fish can be taken out and fed.

Hatching in mouth

That is, the way to feed young fish through the mouth. This kind of fighting fish includes fighting dog fighting fish and Fauci fighting fish. Generally speaking, the male fish incubating fighting fish in the mouth is in estrus earlier than the female fish. After mating, the female fish will help the male fish collect the fish eggs that sink to the bottom of the water. The male fish will twist his mouth from time to time, rearrange and adjust the order of the fish eggs contained in his mouth and chin, so that all the fish eggs can be melted in his mouth to the maximum extent. When all the eggs in the male fish's mouth are contained, the female fish should be removed from the culture pond in time and passed through 10 ~. The hatching rate of oral incubation is high, but the male fish consumes more physical strength. Proper water quality and quiet environment should be ensured during incubation to prevent male fish from swallowing fertilized eggs in their mouths.

Although China is the hometown of these fighting fish, their status at home is very different from that abroad. Many ornamental fish lovers disdain China Betta, and even many wild Betta are sold as feed fish. This is a kind of sadness. I sincerely hope that more friends can know about fighting fish in China and like fighting fish in China. At the same time, I hope that domestic fish friends can also cultivate beautiful new species.
