Marine biologists have recently discovered that fish living in the ocean also have their own doctors-an ordinary small fish. In the vast sea area, nearly 50 species of small fish have been found so far, and they are doing medical work day and night. Their "medical stations" are generally located on coral reefs.

Doctor Fish's Treatment Method "Doctor Fish" who saves the wounded and rescues the dying, and the reason why the sick fish won't eat the doctor fish —— Doctor Fish's neglected treatment right to save the fish's life and adopt the fish.

Brief introduction of Dr. Fish

The "fish doctor" is small and light.

Fish doctor's treatment method

It does not treat fish with drugs, but removes bacteria and dead cells from sick fish through its sharp mouth.

When a sick fish "sees a doctor", it must be suspended in the water with its head down and tail up. If the throat is sick, the sick fish must obediently open its mouth and let the "fish doctor" get in.

The "fish doctor" who saves lives.

Sometimes the fish doctor's "business" is quite prosperous, and even a long queue is waiting for the fish doctor's treatment. But sometimes the order is quite chaotic, and everyone wants to see a doctor early, which will inevitably lead to congestion and disputes. Although the "patient" is in a hurry, the fish doctor is never in a hurry and always works leisurely and carefully. At this time, there will often be scrambling and noisy scenes. In this case, the "fish doctor" who always likes to treat sick fish quietly will also fly into a rage, give up and hide in a quiet place. At this time, sick fish often rush to stop the "fish doctor". In desperation, the "fish doctor" had to restart the treatment work. Strangely, most of the patients are male fish. This may be because males are aggressive and often get hurt. Males love to clean and dress up more than females. It is still puzzling that these fish will change their body color after treatment. It will change from light to red or from silver to bronze. Is this telling the fish doctor what happened to them? The "fish doctor" cures diseases quickly. A marine biologist has been observing the "fish doctor" in the water for six hours. According to statistics, a "fish doctor" actually cured more than 300 sick fish in these six hours!

Marine biologists also found that the male fish who went to see the "fish doctor" went to see different "fish doctors" several times a day. At first, researchers thought that male fish were more likely to get sick. Later, it was found that fierce "love wars" often occurred between males in order to compete for females, so there were more opportunities for injuries, and once they were injured, they had to go to "treatment", which led to a fish seeking "fish doctor" treatment many times in one day.

The reason why sick fish won't eat fish, doctor.

Some people may ask, will sick fish eat "fish doctor"? According to the observation and analysis of marine biologists, this kind of thing will not happen, otherwise, diseases will spread and fish will die in large numbers. So the relationship between sick fish and fish doctors is quite harmonious. All sick fish receiving treatment must honestly "stand" in front of the fish doctor, open their mouths and let the small fish enter their mouths. Even if the enemy attacks, the sick fish will not swallow the "fish doctor" in a hurry, but spit it out first and then run away. Maybe fierce animals swam over during the treatment. At this time, the treated fish will take the fish doctor to a safe place in a hurry, and then come back to fight the fierce animals to death, and never let the little doctor get hurt.

A new occupation-fish doctor

It is common to operate on people, dogs and tigers, but have you ever heard of operating on fish? At present, this industry is rising in the United States, and people in the industry believe that fish surgery has both a future and a way to make a fortune. American Roberts and her assistant Bonnie successfully sterilized a goldfish. Of course, this fish is not the kind that people keep in fish tanks for thousands of dollars (although they also operate on that kind of fish), but a wild goldfish, which Roberts called "goldfish 1". The fish was taken by its owner to the Roberts Clinic in the suburb of Buffalo (a city in western New York, USA). This kind of fish is very common and everyone has raised it, but "Goldfish 1" is a sick fish. Roberts has all the tools on the operating table: a rubber tube filled with water and anesthetic, and a transparent plastic tube connected to an underwater pump. "Goldfish 1" is lying in the bathtub. The yellow foam board keeps it upright. The pipeline inputs anesthetic water through the fish mouth and discharges it from the gills, forming a circulatory system.

According to Roberts, this set of things is basically needed for fish surgery. Some fish doctors have mastered quite high technology, and even some intractable diseases can be cured. Roberts' clinic has adopted many sick fish: Lucy has a 2.5-pound tumor although she weighs only 1.5 pounds; "Sunshine" burst her belly in the process of almost crazy mating; Betty suffers from abdominal hydrops; There are also some goldfish suffering from buoyancy imbalance. For example, "Bob" always swims with his belly up, while "Lavin" swims with his nose down and his tail up. These fish were operated on in the fish clinic in Roberts and recovered.

Neglected right to treatment

However, 10 years ago, it was not easy to find a fish doctor even in the United States, where the medical level was very developed, but this has become history. In the 1970s, cats and dogs finally began to enjoy the same treatment as people, but what about birds? Unless you are crazy. In the 1980s, ornithology appeared in the United States, or at least a monthly magazine devoted to the prevention and treatment of bird diseases, which attracted many pet lovers. Nowadays, doctors can operate on parrots and even transplant organs to dogs and cats every month, attracting many pet lovers. Today, doctors can operate on parrots, even transplant organs to dogs and cats and give gerbils chemotherapy. But if someone takes fish to the vet, people will still think that this person is crazy. Dr. David Scarf, deputy director of the scientific behavior department of the American Veterinary Association, said: "I have no doubt that fish medicine will be as common as bird medicine in the 1980s. In fact, the development of fish medicine and fish surgery is much faster than I thought. "According to the data released by the American Veterinary Medicine Association, nearly 2,000 veterinarians have tried to develop fish medicine and fish surgery so far. Fish doctors have become a new profession, and the number of fish doctors has increased rapidly, and the market prospect is promising. The survey results show that there are about13.9 million families in the United States raising different kinds of fish, and the annual expenditure on ornamental fish alone is as high as10 billion US dollars. The money is mainly used to build fish ponds, install water regulators and food, excluding the cost of treating them. Some fish can spend $654.38 million or more to see a doctor. At present, the price of therapeutic fish tends to be stable: basic examination is 40 dollars, blood test is 60 dollars, and X-ray is 55 dollars. More advanced examinations include: ultrasound 175 USD, CAT scan 250 USD. Doctors can also give fish "nasal feeding", give fish enema, treat fractures, remove deformed eggs, treat scoliosis, and even give fish plastic surgery. However, the most common fish and the headache for fish doctors are those with buoyancy disorders. The swim bladder is an organ of the digestive tract, which is easy to be infected, blocked or deformed, making the fish lose the ability to adjust the air and unable to float or sink correctly. Fish with this disease usually have their bellies up and their backs down in the water. To operate on this sick fish, you need to put a small stone in the fish's stomach to restore its balance. The cost of this operation ranges from $ 150 to $ 1500. Many doctors will first suggest mung bean therapy: feed a mung bean to the sick fish once a day, and gently crush it after cooking, and the effect is better. But doctors still don't understand the mechanism of mung bean therapy.

Save the life of a fish.

Greg Lebatteux, a senior American fish doctor, said, "When I tell some people that sick fish need medicine or surgery, their reaction is almost the same: flush the sick fish out of the sewer and buy another one! In fact, there are several reasons for treating fish. The most important reason is that some fish species are very precious. I have operated on several fish worth 30,000 to 50,000 dollars. If these fish are sick, it is inhuman and wasteful to abandon them. " Another reason is that many people have established strong feelings with their own pet fish, which people who don't raise fish can't understand and appreciate. People often say that dogs understand human nature. In fact, many fish farmers say that their fish also understand human nature. They will never throw the fish away because they are sick. They will try their best to save the fish's life. David Smalls is such a person. He keeps a barracuda in the fish pond. Last summer, lightning struck a tree near his fish pond, damaged the northern pike and broke its back. Smalls took it for X-ray examination, CAT scan, spinal massage and spinal surgery to make the northern pike recover. During physical therapy, Smalls asked for leave to stay in the fish pond for several weeks, clutching the fish tail with his hands, for fear that the fish tail would shake and make the wound difficult to heal. Talking about the experience of treating fish, Smalls couldn't help crying.

A proposal to adopt fish

At the recent Singapore International Fish Exhibition, the organizer announced a proposal for fish adoption, declaring that "fish has life and feelings". Therefore, treating fish is a humanitarian move, and you can't simply pour them into the sewer.
