Treatment of common diseases of parrot fish

Parrot fish, also known as parrot fish, is a kind of tropical fish living in coral reefs, colorful and highly ornamental. So, what are the common diseases of parrot fish? What are the treatments? Let's get to know it together.

1. White spot disease

White spot disease is a highly contagious external parasitic disease, and it is also a common disease of parrot fish. White spot disease has the following symptoms: in the early stage, each fin and body have individual small white spots, which have appetite and little change in spirit; in the middle stage, the fins and body are full of white spots, no appetite, no activity, scratching everywhere, and the color darkens. In the late stage, the white spots covered the whole body, the fish floated on the surface or sank into the bottom of the box, the fish were weak, swayed left and right, increased mucous membranes on the body surface, difficulty breathing and suffocated to death.

If the disease is to be treated comprehensively, medicine alone is not effective, and it is very important to strengthen feeding and management. first of all, it is necessary to stop eating for 4-5 days, reduce pollution, keep the water temperature constant, the temperature is 2-3 degrees higher than the original water temperature, and can be properly administered in the absence of aquatic plants. Aquatic plants are sensitive to various drugs and die quickly. The commonly used prescriptions are as follows:

In the early stage of ①, 0.5% or 1% salt can be used, and some results can be achieved.

In the early and middle stages of ②, furacillin powder of 1~5ppm can be used to sprinkle the whole box. Dip the match stick in methyl blue crystal powder and rinse it into the diseased fish box to change color, all of which have good results.

In the early and middle stages of ③, red mercury was put into water and turned light red, which had a good effect on killing pathogens, but could not be used repeatedly because mercury was toxic and it was not easy for fish to be excreted from the body.

In the middle and late stages of ④, the specific drug is mercurous nitrate, but fish are very sensitive to this drug and are easy to cause death, so it is generally not used. You can put a piece of mung bean in a 90 × 45 × 60 (cm) box, and this medicine can not be used repeatedly.

2. Hemorrhagic rot

Hemorrhagic rot is a bacterial infectious disease. after getting hemorrhagic rot, the fish appears bleeding spots, each fin changes from bright red hyperemia to pale and rotten, the cheek wire also changes from red to white, partially rotten, anatomical viscera has bleeding spots, often complicated with enteritis, the disease is urgent, and spreads fast. in general, two to three days, it is easy to cause a large number of deaths.

For the treatment of this disease, stop eating for 4-5 days, put penicillin 90 × 45 × 60 (per cent) box 800000 units in the whole box, one in the morning and one in the afternoon, for 3 consecutive days as a course of treatment, generally 4-5 days can be cured, the initial stage can be cured, the middle period can be controlled, the rotten fins need about 1 month to grow well, pull out the water plants from the affected box, rinse with clean water and disinfect with methylene blue for 15-30 minutes. When furacillin powder (1-5ppm) is put into the sick fish box, it can be controlled in 3 days and cured in about 6 days.

3. Rotifer

Rotifer is infectious protozoa. The symptoms of rotifer are rotifer gathering in the box, fish floating on the water surface, parasitic everywhere in fish body and Gill, increased mucous membrane of color body, dyspnea. If diseased fish are not treated in time, a large number of fish will die.

The best treatment 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. The 90 × 45 × 60 (cm) box can put mung bean-sized crystal blocks. Aquatic plants are particularly sensitive to copper sulfate. To pull out the grass and then apply the medicine, you can not use the partial water change method to deal with it. Instead, it will accelerate the mass reproduction of rotifers and accelerate the death of fish, so it is necessary to change the water and the medicine at the same time. In addition, it can also be treated with 0.5%, 1% concentrated saline is also effective.

4. Water mildew

Water mold is a fungal infectious disease. The pathogen of water mold is a variety of water mold. There are molds everywhere in houses that have raised fish for 2-3 years. Fresh water can pollute mold in 2-3 days. When the fish is not injured or the fish is strong, it does not occur. If the fish has trauma, it can occur immediately. Although the incidence is not high, the mortality rate is not high, but the course of the disease is long, it is not easy to cure, and the fish eggs are more likely to be infected.

There is no specific cure for water mildew, mainly to prevent, keep the water quality clean and strong, be light in daily operation and fishing, do not cause fish body trauma, use 0.5% UV radiation, pay attention to ventilation and bask in the sun, and increase ultraviolet radiation. In addition, you can also fish out the affected fish, remove the white hair from the injured area with tweezers, and apply some furacilin dry powder to the affected area, which has a certain effect.
