Three years ago, Mr. Zheng, a citizen of Xuzhou, bought 4 walrus fish in Guangzhou on a business trip and took them home to keep as pets. It's too fast. It was only 20 centimeters when I bought it, and now it is 1 meter long. After some inquiries, I learned that the 1-meter-long walrus fish is still small, and the adult walrus fish can grow to 4 meters long and weigh 400 pounds. Now Mr. Zheng is worried, Even if I vacate my living room and change it into a big fish tank, it will not be enough for this guy to live! In desperation, yesterday morning, Mr. Zheng presented the fish to Xuzhou Yunlong Lake Aquarium.

Mr. Zheng's walrus fish is currently 1 meter long

I bought a fish for 1,000 yuan and shipped it home by air

Mr. Zheng, who is in his 40s, lives in Xuzhou City Railway No. 29 Dormitory, and opened a special production shop near his home. Small company with glass fish tank. Mr. Zheng loves to keep fish. There are various fish tanks in his office, and the largest one is very different. This fish tank is 1 meter high and 2.5 meters long. The water in it is very turbid. The heating rods in the water are constantly working, and a one-meter-long big fish is slowly swimming in the fish tank.

“This is the walrus.” Mr. Zheng said that three years ago, he was on a business trip in Guangzhou and met a fishmonger who had a lot of walrus fry in his hand. “The fish were not big at that time. It's only 20 centimeters long, shiny all over, and looks very cute. Mr. Zheng fell in love with it at first sight, so he spent 4,000 yuan to buy four of them and shipped them back to Xuzhou by air.

When buying walrus fish, Mr. Zheng didn't know much about walrus fish. It was purely out of a hobby for breeding unfamiliar fish species. After returning, the walrus fish's appetite became larger and larger, and its body became longer and longer, and Mr. Zheng felt that something was wrong. The growth is too strong. Originally, it only ate two or two small fish a day. Later, it increased to half a catty, and it didn't take long for the food intake It has increased to more than one kilogram, and now I eat at least two kilograms of small crucian carp a day. Now, after raising it for three years, the fish has grown from 20 centimeters to 1 meter, and it is still growing wildly.

The fish grows too fast, and I am so worried

Mr. Zheng is so worried that the biggest fish tank in the house can hardly fit. . A knowledgeable person told him that the 1-meter-long walrus is still in its infancy, not yet an adult, and will grow to three or four meters long in a few years. It's not enough to turn my living room into a fish tank when it grows to three or four meters long.

As the fish grew bigger, an accident happened. Because the fish tank is too small and the space for four fish at the same time is very cramped, the walrus fish often jump out of the water, Sometimes the fish jumped to the ground and didn't have time to pick it up because there was no one around, and they died, and three died one after another. The fish that have been raised so hard are dying one after another, which is a blow to Mr. Zheng, who loves fish. He is determined to give the last walrus to those who can feed it.

Someone inquired about this and came to visit in person and came up with a high price to buy the walrus in Mr. Zheng's hands, but was rejected. The reason is that the person who came here doesn't seem to know how to raise fish, and he doesn't even know the basic knowledge of walrus fish. Mr. Zheng said that the other party looked like a local tyrant, and he probably wanted to buy the fish back and eat it. He offered 10,000 yuan, but I didn't agree.

Later, someone suggested, why not send the fish to Yunlong Lake Aquarium, where there are professional breeders and equipment, Mr. Zheng immediately became enlightened, and quickly Contact the aquarium.

The fish was delivered and asked to keep the fish well

Yesterday morning, the aquarium staff came to Mr. Zheng's place with a copy net and a transport box. In the office, the walrus fish was fished out and taken away. After raising it for three years, there was only one single seedling left. Mr. Zheng was a little reluctant, but he said that he would visit often, and repeatedly told the aquarium staff to keep this fish well. Zheng Shanyue, a breeding engineer at the aquarium, said they would keep the fish with another 1.5-meter-long young walrus in the aquarium. Mr. Zheng can look at it at any time, and you can directly comment if it is not well raised.

The walrus fish can grow up to 4 meters long and weigh 400 pounds

Zheng Shanyue, a breeding engineer at Xuzhou Yunlong Lake Aquarium, told the Modern Express reporter that the walrus, known as Arapaima because of its tongue, has a lifespan of about 15-20 years, a body length of 3-4 meters and a weight of 400 pounds. One of the largest scaly freshwater fish on the . The walrus feeds primarily on small fish, but occasionally also prey on snakes, turtles, frogs, insects, and even small crocodiles. Mr. Zheng's fish is only 1 meter long and weighs 20 pounds. It can only be regarded as a juvenile fish, and the market transaction price should not be less than 10,000 yuan. The adult walrus has an activity range of at least 10 square meters and a water volume of more than 10-15 tons. Ordinary citizens cannot afford to keep it at all.

Walrus is an exotic species that mainly lives in the Amazon River Basin. The sale of this fish is not prohibited. However, walrus fish are not suitable for breeding as ornamental fish due to their fast growth rate and high requirements on the surrounding environment. Similarly, it is not suitable for natural release. The suitable water temperature for walrus fish is 25-28 degrees Celsius. If it is released, it is estimated that it will die within a few hours.
