"Brother, please don't leave." The young man in leather jacket stopped Xiang Yang and said, "I know a milk tea shop that has very good milk tea. Can I invite you to have a cup of milk tea?"
Xiang Yang looked at the young man in leather jacket with a smile, "I won't drink the milk tea. If you have anything to say, just tell me here."
The young man in leather jacket rubbed his hands and asked carefully, "You just said that this kind of fish reproduces by fission?"
Xiang Yang raised his eyebrows, "This kind of fish?"
The young man in leather jacket looked a little embarrassed. "Brother, I really didn't mean to lie to you. I really don't know what kind of fish these are, but they do look very beautiful, so I call them sea goldfish."
Chen Qingsheng said slowly: "You just said that you raised these fish yourself, but it seems that you don't even know what kind of fish they are."
"I caught it in the sea." The young man in leather jacket said immediately, "This fish is very stupid. It sticks to the reefs and plants at the bottom of the water and immediately stops moving, just like it has taken root. But this fish is too small, so it's hard to find."
"Where did you catch him?" Xiang Yang asked.
"In..." The young man in leather jacket rolled his eyes a few times and hesitated again.
This micro goby is his main source of income. I don't know how many people have asked him about the origin of this micro goby. He never tells anyone where he catches these fish, not even his relatives and friends.
"Chen Qingsheng, let's go." Seeing this, Xiang Yang directly called out to Chen Qingsheng.
"Okay, boss." Chen Qingsheng responded immediately.
"Wait, big brother, wait a minute." The young man in leather jacket became anxious again when he saw Xiang Yang was about to leave.
Xiang Yang stopped and looked at the young man in leather jacket quietly.
The young man in leather jacket said quickly: "If I tell you where this fish comes from, can you tell me how to breed it?"
Xiang Yang shook his head. "I don't like to tell lies. Even if I tell you how to breed this kind of fish, you still can't breed it. It has high requirements for the environment and food. One of the most basic requirements is that it needs to live in running water with microorganisms such as phytoplankton. Can you meet these requirements?"
The young man in leather jacket froze, "Does it need running water?"
Xiang Yang nodded, "We must have running water."
This is the frustration of people who play with marine aquariums.
Many marine fish are obviously more ornamental than freshwater fish, but their value is often less than one-tenth of that of freshwater fish.
Why
Because the cost of having a marine aquarium is really too high, it is simply not affordable for ordinary people.
Of course, if the person who plays with the marine aquarium is really rich, then everything is a different matter.
For example, Bill Gates, the founder of Microsoft Computer, has an ocean tank, and it is a super giant one. He keeps a whale in his own yard and hires people to drive to the sea every day to haul seawater to change the water for the whale.
It is absolutely awesome to have a whale.
In terms of ornamental value, it crushes koi and arowana.
However, there is no second Microsoft in the world, and there is no second Bill Gates in the world. There are only a small number of people in the world who have the ability to do this. Some ornamental fish are not worth promoting at all.
The young man in leather jacket silently counted the strokes.
If breeding these small fish requires running water and has extremely high requirements for water quality, then he really has no way of breeding them.
Instead of spending so much money to breed this kind of small fish, he might as well go into the sea and catch it himself.
"I'm sorry." The young man in leather jacket finally shook his head and said, "Since I can't cultivate these small fish, I can't tell you where they come from."
The young man in leather jacket grinned, "I depend on these small fish for my living."
Xiang Yang pondered for a moment and said, "If that's the case, then I won't force you. But let me ask you a question. Have you ever seen this kind of lobster when you were fishing for these small fish underwater?"
As he spoke, Xiang Yang took out his mobile phone, searched for a picture on Baidu, saved the picture in the album, then opened the album and handed it to the young man in leather jacket.
"Let me take a look." The young man in leather jacket took Xiang Yang's phone and looked at it carefully.
It was a very colorful shrimp with two very asymmetrical claws, one big and the other small.
The young man in leather jacket looked at it carefully and nodded, "I have seen it before. I have even caught and eaten it, but the shrimps are too small, there is not much meat, and it is troublesome to peel them, so they cannot be made into shrimp meat."
Xiang Yang raised his eyebrows, "Catch it and eat it?"
"What? These shrimps can't be eaten?" the young man in leather jacket asked anxiously.
Xiang Yang was silent for a while.
Micro gobies are already a popular ornamental fish in marine aquariums and are quite expensive, but they are nothing compared to this tiny shrimp.
The name of this shrimp is pistol shrimp.
Pistol shrimp are a very aggressive type of shrimp that live in symbiosis with gobies.
Where pistol shrimps can be found, there must be micro gobies, but where micro gobies can be found, there may not be pistol shrimps.
Pistol shrimps cannot see anything with their eyes, and they are not very large in size, so they are considered to be consumers at the lower end of the food chain. They also have many natural enemies, such as crabs, carnivorous fish, octopuses, etc.
Even though pistol shrimps have lived in shallow sea areas for generations, they still encounter various natural enemies every day, and they always form racial groups. When they encounter natural enemies, the enemies often only need one bite to kill half of their population.
Therefore, this kind of shrimp is very precious. Some good quality ones are more valuable than the same amount of gold. Even those with average quality can be sold for dozens of yuan each in the ornamental fish market.
Pistol shrimps are also called drum shrimps. Although they are very small, they are known as the noisiest and most powerful creatures in the world.
The two claws of the pistol shrimp are of different sizes, one is very small and the other is very large.
Pistol shrimps can shoot out a high-speed bubble of water at the moment they close their claws, just like a bullet, so they are called pistol shrimps.
It is said that the bubble shot out by the pistol shrimp takes less than one second from its emission to its explosion, and the temperature after the explosion can reach 4,700 degrees, the speed can reach 100 kilometers per hour, and the sound can reach 210 decibels, which is enough to stun many small aquatic animals.
The micro goby has no means of attack, and the pistol shrimp's eyes are really blind, but they are both carnivores and live in warm shallow waters, so they form a symbiotic relationship. In this symbiotic relationship, the micro goby plays the role of a guide dog, guiding the pistol shrimp, and the pistol shrimp plays the role of a hunter. Whenever the micro goby sends a signal that there is food ahead, the pistol shrimp will fire in groups, stunning the prey, and then they swim over together to enjoy the meal.
