What is the disease with the eyes protruding from the parrot fish? how many years can the parrot fish live?

Everyone has three illnesses and two pains, not to mention fish. Now one of the most common diseases of parrot fish in the aquarium is exophthalmos. Usually the reason for this disease is that the water quality in the water tank has changed and the living conditions in the water do not conform to the healthy growth of fish. Although the incidence of this disease is not very high, as long as fish are available, it is difficult to treat and the mortality rate is extremely high.

What disease is the parrot fish's eyes protruding?

1. No matter what kind of fish you raise, it is impossible not to get sick. In the face of the common diseases of parrot fish, we should detect them as soon as possible and treat them as soon as possible. Parrot fish exophthalmos is one of the common diseases, many people have heard of this disease, but do not know whether their fish have this disease.

2. The main reason for the protruding disease of parrot fish is the problem of water quality. some fish lovers cannot change water for their favorite fish on time due to various reasons, or the filtration of the fish tank is not effective, resulting in aging water quality and bacterial infection.

3. Another reason is that fish friends can not clean up the garbage residue in the tank on time, and all kinds of harmful bacteria breed seriously in the dirty water. Even strong parrot fish can be invaded by harmful bacteria and suffer from various diseases when growing in such water.

How many years does a parrot fish usually live?

1. The life span can reach 4-5 years, which may be longer. Please don't expect the eggs to hatch. Parrot fish are hybrid fish, so parrot fish eggs can't hatch. So far, people have not been able to hatch the eggs laid by parrot fish. Let them eat, or you should clean up the eggs so as not to pollute the water.

2. So the eggs between the parrot fish cannot reproduce, which is equivalent to a mule and is infertile. If you want to get the parrot fish, you can only breed through the red devil and purple fire mouth. Although spawning is the nature of fish, the eggs between parrot fish cannot hatch, so don't wait for it to hatch, it's useless. Although parrot fish cannot reproduce each other, female parrot fish can mate with fish such as Luohan and the Red Devil and give birth to small fish.

How to raise parrot fish

1. Raising parrot fish, knowing that the water temperature of parrot fish is very important, the parrot fish has strong adaptability, and the water temperature can survive between 25 degrees and 30 degrees, but 28-29 ℃ is the best. Parrot fish prefer new water, and it is more appropriate to change it to 5% fresh water every week. If the water quality is weakly acidic and refreshing, do not change the water frequently, because the stable water quality is more suitable for the reproduction of nitrifying bacteria.

2. In order to make the body color of the parrot fish better, some fish friends increase the light, strengthen the filtration, thicken the filter material, and heat the water temperature of the parrot fish to 28 degrees. These are all practical ways to maintain the body color. And in the new change of water, we should pay attention to maintain the consistency of water quality and the difference of water temperature, and the water temperature difference before and after each change of water should not exceed 0.5 ℃.

3. if the water temperature of the parrot fish is too high, we need to take some cooling measures. You can fill the beverage bottle with water and freeze it in the refrigerator, and then put it in the tank to cool down.

Prevention and treatment of common diseases of parrot fish

1. White spot disease

[symptoms] White spot disease is a highly contagious external parasitic disease. Parrot fish infected with white spot disease have individual small white spots on each fin and body in the early stage, white spots everywhere in the middle stage, and white spots all over the body in the late stage, the fish will be weak, swaying left and right, increased mucous membranes on the body surface, difficulty breathing, suffocation and death.

[prevention and treatment] the disease should be treated comprehensively, but only medicine is not effective, and it is very important to strengthen feeding management. First, stop eating for 4-5 days, reduce pollution, keep the water temperature constant, and the temperature is 2-3 ℃ higher than the original water temperature. 0.5% 1% salt can be put into the early stage, and certain results can be achieved. In the middle stage, 1-5ppm furacilin powder can be used to sprinkle the whole box or put red mercury into the water. It has a good effect on eliminating pathogens, but it can not be used repeatedly because mercury is toxic and it is not easy for fish to be excreted from the body.

2. Rot disease

[symptoms] the rot disease is a bacterial infectious disease. When the parrot fish is infected with hemorrhagic rot, the fish appears bleeding spots, each fin changes from bright red and hyperemia to pale and rotten, and the cheek silk also changes from red to white, part of it rotten, and the disease is generally urgent and spreads quickly, causing a large number of deaths in 2-3 days.

[prevention and treatment] stop eating for 4-5 days, pull out the water plants in the box, rinse with clean water and disinfect with methylene blue for 15-30 minutes. The whole box is filled with penicillin, which can be controlled and cured in 4-5 days.

3. Rotifer

[symptoms] rotifer is an infectious protozoa. When rotifer occurs, rotifers gather into clouds in the box, and fish float on the water surface and parasitize everywhere in fish and Gill. The mucous membrane of the color body increased and it was difficult to breathe. If diseased fish are not treated in time, a large number of sick fish will die.

[control methods] rotifers are mostly transmitted by feeding water fleas, so new fish and worms should be washed many times before they can be fed to the fish, otherwise it is easy to get the disease. the best way to get sick is to pour out the whole box of water, move the fish into the new box, and add some medicine. the specific medicine for the treatment is copper sulfate, and pay attention to no water plants in the water tank.

4. Black spot

[symptoms] when black spot disease occurred in parrot fish, black spots appeared in the fish body, which was gray and white, and the hyphae wound and adhered to the cells and tissues of the wound, resulting in tissue necrosis. At the same time, the diseased fish lost their appetite and finally died.

[prevention and control methods] A small amount of salt can be put into the aquarium of new fish to inhibit the occurrence of water mold, pay attention to cleaning and disinfection when putting live bait, and the water quality can be kept clean to isolate the growth of water mold, which can generally prevent the occurrence of this disease.

5. Skin mycosis

[symptoms] skin mildew, also known as water mildew and white disease, is one of the most common diseases of ornamental fish. it is mainly careless when fishing and transporting ornamental fish, which injures the skin of the fish, or parasites invade the skin, the spores of mold invade the wound, absorb nutrients, and germinate rapidly. the hyphae go deep into the muscle at one end and grow outward at one end to form cotton hyphae. The skin of infected fish is usually covered with a layer of white nebula, especially black and red fish, thus losing the luster that the fish should have, and then moving slowly, often dull, floating on the surface, if left untreated, the mold spreads, muscle decay and loss of appetite in the affected area lead to death.

[prevention and control methods] attention should be paid to prevent damage to fish bodies and parasitic bites during operation, and a small amount of salt can be put into the water to inhibit the occurrence of water mildew. When it is found that the fish is infected with water mold, it can be washed with 3% salt water, once a day, 5-10 minutes each time, and other methods to inhibit the growth of water mold. The installation of a 15-watt ultraviolet lamp at the top of the aquarium for several hours a day can also effectively restrain or eliminate the growth of water mildew.

6. water mildew

[symptoms] Water mildew is a fungal infectious disease, and the pathogen is a variety of water mold, which is mainly transmitted through water fleas and diseased fish. although it is contagious, the incidence rate is not high and the mortality rate is not high, but the course of the disease is long and it is not easy to cure it. Long white hairs or white hairs entangled in fish injuries.

[prevention and treatment methods] there is no specific cure, mainly prevention, pay attention to keep the water quality clean, and the fish body is strong, ventilated and bask in the sun, increase ultraviolet radiation, and flowing water are the best preventive measures. The infected rain can be fished out. Remove the white hair from the trauma with tweezers and apply some furacilin dry powder to the affected area, which has a certain curative effect.

7. Furunculosis

[symptoms] furunculosis is a bacterial infectious disease. When parrot fish develop furunculosis, hard vesicles grow from the muscle layer, and sometimes a large amount of purulent blood can be shed.

[prevention and treatment] after soaking, the operation is performed to remove pus, then rinse with furacilin water, better results can be obtained by applying furacillin dry powder or antibiotic powder, and serious ones should be eliminated immediately. Large fish can be injected with penicillin (40-80,000 units) or rinse the sore surface with solution.

8. Gill rot disease

Gill rot disease is a bacterial infectious disease, when it occurs, the cheek silk changes from bright red to pale, begins to rot and fall off from the outer edge, congestion in the parotid bone, necrosis and shedding of the central bone, increase of mucous membrane between the parotid filaments, dyspnea, and the light ones float to the surface. The heavy ones died quickly at the bottom of the caisson.

[prevention and control methods] individual fish get sick and get rid of them. If the disease is common, the whole pond should be sprinkled with pesticide and stop eating for 4-5 days. Furacillin powder can also be sprinkled at a concentration of 1-2ppm.

For those who are four to five years old, it should be no problem to survive for more than six years under the careful care of their owners. Because its growth cycle is 3 years, it may be reasonable to live 10 years in theory, but most people raise it for only three years, which is closely related to the surrounding environmental impact.
