Fish with too many leeches will die, so you can do it in moderation, not too much.
Aquarium fish simply refer to those fish that have ornamental value, bright colors or peculiar shapes. It is said that there are 30,000 to 50,000 species of fish in the world, of which there are 2 to 3,000 species of freshwater fish that can be viewed, but only about 500 species are actually commonly raised and common.
Some of them live in freshwater, some in seawater, some from temperate regions, and some from tropical regions. Some of them are known for their brilliant colors, some for their strange shapes, and some for their rarity and preciousness.
In the world ornamental fish market, they are usually made up of three major strains, namely temperate freshwater ornamental fish, tropical freshwater ornamental fish, and tropical marine ornamental fish.
Ornamental fish mainly include marine fish, tropical fish, goldfish, koi fish, and other freshwater fish, which are called according to customary names in classification, and the classification is not necessarily correct.
Tropical fish: including lipid carp, cyprinidae, ichthyidae, cichlid, climbing perch, loach, catfish, etc.
Arowana: An ancient fish of the genus Tropical Fish.
Colorful Angelfish: This belongs to the family Cichlid in tropical fish.
China's goldfish: This is the "quintessence" of China, but many new varieties have been cultivated abroad.
Koi fish: Cultivated in many countries, but the best species are from Japan.
Marine fish: There are so many species that only a few hundred can be kept in aquariums.
Other fish: cold-water fish and soda fish.
Goldfish. Ornamental fish.
The domestication of goldfish has gone through two stages of pond culture and pot culture, after several generations of folk artists carefully selected, from the initial single-tailed golden crucian carp, gradually developed into double-tailed, three-tailed, four-tailed goldfish, the color is also from a single red, gradually formed red and white flowers, five flowers, black, blue, purple, etc., the body shape has also developed from a narrow spindle shape to an oval, spherical shape, etc., and the variety has also developed from a single golden crucian carp to dozens of colorful varieties, such as dragon eye, Chaotian dragon, blister, lion head, tiger head, pom-pom, pearl scales, Crane top red, etc. According to historical records, China's goldfish was first introduced to Japan in the Ming Dynasty and again in 1615-1623.
The original species of Japanese koi is red carp, which was introduced to Japan from China in the early days, and has gradually become one of the world-famous ornamental fish after careful breeding by the Japanese people. The main varieties of Japanese koi fish are red and white, Showa tricolor, Taisho tricolor, and Akitsui.
Marine fish. Seawater ornamental fish mainly come from the coral reef waters in the Indian Ocean and the Pacific Ocean, with many species of strange body shape, rich body color, extremely varied, good at hiding, and have a primitive and mysterious natural beauty. Common production areas include the Philippines, the South China Sea, Japan, Australia, the Hawaiian Islands, India, the Red Sea, and the east coast of Africa.
Tropical marine ornamental fish are extremely diverse, they live in the vast oceans, many of which are inaccessible to people, and there are many species that have not been discovered by humans. Tropical marine ornamental fish is the most promising ornamental fish in the world, representing the future development direction of ornamental fish.

Grasshopper is a common name for the phylum Annelids and vermicules. Unlike other annelids such as earthworms or sand silkworms, most of these animals live in vitro parasitism temporarily. Adapted to this lifestyle, the locust has no bristles on its body, has suction cups at the front and back ends, and has a muscular body, and the body cavity is divided and filled by muscles and connective tissues and shrinks.
Grasshoppers are a highly specialized annelid. At present, there are more than 300 species known in the world. Most live in fresh water; a few are marine or brackish water species; There are also some terrestrial or amphibious; It is mostly in warm and humid areas.
The size is between 4 and 200 mm. Grasshoppers have ringed bands and are hermaphroditic. Therefore, it is generally believed to have evolved from a class of oligochaete ancestors adapted to ectoparasitism.
Many species of grasshoppers feed on the blood of vertebrates or invertebrates. Some are more or less fixed to live on an animal individual, close to ectoparasites; Some only temporarily invade the host, sucking up the blood and then falling down; But there are also common predatory or saprophant. [1]
Morphological characteristics. Grasshoppers generally have a flat dorsal and ventral, a narrow anterior end, and are leaf-like or worm-like as a whole. Body shape can change depending on how much you stretch or how much you eat.
The body segments, and the anterior and posterior segments evolve into suction cups. The anterior suction cup is small and often surrounds the mouth; The posterior suction cup is cup-shaped, mostly towards the ventral surface. Except for spiny leeches, the segmentation of the body is relatively fixed, indicating that they are closely related and have a high degree of specificity.

How long has this fish not eaten? If it doesn't take long, it's probably digesting, but the locust is a very nasty thing and has a lot of vitality.
-
In a pond with fish, it is difficult to kill leeches alone, only after the fish are cleared, they are all killed with copper sulfate, so that they can be killed. If the water is pumped directly from the river to the fish pond, the leeches are pumped up from the river again, and there are again. You should pay attention to this.
The river water should be treated and then put into the fish pond, so that there is no more.
-
Most fish do not eat leeches, on the contrary, leeches are the natural enemies of fish, and can suck the fish dry and die. Except for a few ferocious fish, such as cichlid fish, pearl tiger, etc.
Leeches, also commonly known as leeches, feed on plankton, small insects, mollusc larvae, and muddy humus when they are young. When an adult, it will attack fish and shrimp, and will even attack the player's hand that reaches into the fish tank.
Leeches stretch and contract their bodies, alternating between using suction cups as attachment points to swim. A suction cup has a mouth hidden in it, which can cause trauma, through which the leech sucks a large amount of blood from the fish. If the leeches are not removed in time, the fish will be sucked dry of blood and die.
-
Some goldfish may eat it, but if the size difference is relatively large, the fish may be eaten if it is large. However, if there are leeches in the fish tank, it is recommended to clean them up in time. Otherwise, it may cause leech disease in fish, and it is not good for leeches to adhere to the body of the fish.
It can have an impact on the health of the fish.
-
Fish do not eat leeches because of their different habits.
-
Depending on what kind of fish it is, carnivorous fish will eat it.

I don't know, but I've seen leeches suck the blood of fish.

Well water is a source of drinking water in many areas, and it can easily be polluted, and leeches can also grow, which is frightening. How to deal with leeches in the well water.
1. It can be removed by sprinkling salt. ** is the first protective barrier of animals, and mollusks (including locusts) are not**, after sprinkling salt, salt and its body fluids form a high concentration of saline, which promotes the extravasation of low concentration of body fluids inside, resulting in its dehydration and death. Leeches in a highly concentrated salt solution will die due to water loss.
2. According to the amount of water stored in the well, calculate the normal use of disinfectant (bleaching powder or bleaching powder), and then put two to three times the normal amount of disinfectant into the basin, add a small amount of water, stir evenly and pour it into the well water, cover the well and seal it for one hour, and the leeches in the well wall and well water can be killed.
3. You can also trap leeches: put a loofah sac soaked in pig blood (chicken and cow blood can do it) into the water, and take it out in the middle of the night to kill the leeches in the loofah sac. Or use a number of pig blood, wrapped in straw, tie the straw, tie a heavy object below, hang on the edge of the well with a rope, if there are leeches, it will definitely enter the straw bag, and you can also extract the bones stained with blood in the raw meat, fish in a place 4 cm away from the well water, and wait for the leeches to be attached to the bones, take them out and burn them.
Repeat several times until there are no leeches. Then dig the well and disinfect it.

In just one minute in water with a temperature of more than 80°C, adult leeches and fertilized eggs will die.
In traditional Chinese medicine, the grasshopper is a medicinal herb that invigorates blood circulation.
Leech, commonly known as leech, has been recorded in the "Shennong Materia Medica" and has a high medicinal value; It grows and breeds in inland freshwater waters, and is a traditional Chinese special medicinal aquatic animal, and its dried products are soaked in traditional Chinese medicine, which has the effects of stroke, high blood pressure, stasis, amenorrhea, bruises, etc. In recent years, it has been newly discovered that leech preparations have special effects in the prevention and treatment of cardiovascular and cerebrovascular diseases and anti-cancer. It is mainly natural fishing in history, due to the abuse of pesticides and fertilizers in recent years, as well as the pollution of the environment by the "three wastes" of industry and agriculture, the wild natural resources have decreased sharply, and with the in-depth development of the medicinal value of leeches, its market demand potential is huge.
Around 1995, southern China began to harvest natural seeds, and for the first time they were raised in captivity, which was successful. In the northern region, there has been no cultivation for seed and technical reasons.

Do not worry.
In traditional Chinese medicine, the grasshopper is a medicinal herb that invigorates blood circulation.
It only takes one minute in water with a temperature of more than 80°.
Both the adult worm and the fertilized egg die.
Leeches attach themselves to the fish.
It is usually sucked by its blood.
Instead of breeding.
Now that you have cleared the locusts.
There is a cooked it.
Then you can enjoy it with confidence!

This is to say that leeches will not be because of the above several ways.
and die. In the biological world, many animals have a strong ability to survive and heal themselves, and can adapt to the harsh environment in the eyes of humans. Leeches are one such creature. It can survive in high temperatures and heal quickly when cut off (much like earthworms).
But that doesn't mean leeches won't die. Leeches have an Achilles' heel, that is, they are afraid of salt. This is because, in a high-salinity environment, its homeostasis will be disrupted, and it will die of severe dehydration.
A very simple experiment can be done by sprinkling a spoonful of salt on a leech, and within a few seconds it will "melt" and die within a few seconds.

Even if you put it in the stove and burn it to ashes, and then put it in the water, it will still come back to life.
If you think about it with your brain, you know that it can't be 0....

It is impossible not to die, any living thing will die. This is the law of nature. There are no exceptions, the easiest way is to use salt and tobacco bag oil, which should be a lot in the countryside, especially salt is available, use salt to dehydrate it for a long time and it will die.

Impossible. Do you think that if it doesn't die, all creatures have a tendency to overreproduce, and if you get it now, wouldn't it be the world of leeches? Upstairs is right, there's also a way to use cow urine.
No, it won't! Mudskippers can get out of the water and mudskippers can survive on land for long periods of time. If you don't swim out of the water regularly, you'll die. >>>More
When the fish is about to die, they are short of oxygen and urgently need oxygen, so they open their mouths wide to inhale more oxygen. The fish opens its mouth to suck the water in, and then drains the water from the gills, while the gills filter oxygen into the body, and the fish is breathing. >>>More
No, it won't. 1. The dog's ascites is decided whether to pump or not according to the serious situation. If there is not much ascites, it can be solved by taking medicine. If ascites is severe, it needs to be withdrawn. >>>More
Ability also has restraint and level, Ace is a fire ability, but Akainu's ability is volcanic magma that can melt even fire, and the level is also higher than Ace.
In fact, tears were originally used to secrete salt, and it seems that only some mammals and some reptiles and birds living in the marine environment have tear ducts. Turtles and seabirds shed tears and dry to leave white salt. Mammals with lacrimal glands also appear to be involved in marine life. >>>More
