How can the tropical fish I raise be white all over

It is believed that it is caused by the ectoparasite (small melon worm) of fish, which is more likely to occur at the turn of the season.

**Method 1: Raise the water temperature to more than 30 degrees, add a pinch of salt, and add oxygen for 24 hours. This method is relatively safe and effective for white spots.

Note: If there is grass in the fish tank, heating may cause the grass to die, and the grass tank is not recommended. If there is a scavenger in the fish tank, adding salt may cause the scavenger to die, and if there is a scavenger, you can't add salt, just heat up and add oxygen.

**Method 2: Add yellow powder or methyl blue, these two medicinal properties are relatively mild, suitable for use in grass tanks, and can also treat other diseases, such as rotten tails. After being cured, there is no need to change the water in the whole tank, and the water pollution is small.

**Method 3: Add white spot net, the effect is fast, but the water pollution is heavy, and this medicine contains harmful ingredients to the human body, it is not recommended to use it in very serious cases. After the medication, the water should be changed in the whole tank.

**Method 4: Use potassium permanganate, potassium permanganate can not be placed directly in the fish tank, to be dissolved in another container, the proportion can not exceed 1/5000, put the sick fish in, 5-10 minutes after the medicinal bath, the sick fish are fished out, and the diseased fish are conditionally separated into separate tanks. This kind of effect is fast, but it is more harmful to the fish, and improper use may also cause the death of the fish, so it is not recommended to use.

White spot disease is not difficult to treat, and when changing seasons, pay attention to the water temperature of the water change should not differ more than 2 degrees from the water temperature in the fish tank, which can reduce the incidence of white spots.

That's all you can think of, I hope your little fish will be healthy :)

If you have the most common white spot disease, the reason for the low water temperature, the water quality is bad, you can increase the water temperature to 28 degrees to 30 degrees, increase the grain salt in the tank, at this time the fish try to feed as little as possible, and wait for the white spots to be less in the slow change of water, you can also add gentamicin.

If you get sick, it's either white spot disease or water mold disease.

If you are able to eat normally, there may be three reasons:

1. The water temperature is low.

2. The feed is not good.

3. The fish is dyed.

If you are sluggish, you may be sick, pay attention to the water quality.

It is best to choose a special **white spot disease drug**, which can make tropical fish recover faster, and the white spot treatment method on the tropical fish body is because of the white spot disease caused by the small melon worm infection, only need to change the water, strengthen the filtration system, and raise the temperature to about 30 degrees, rest for a week to see if it can be cured.

It must be a lack of water, and I would suggest that he change some clean water sources and give him some food every day.

Usually after the fish are sick, they need to stop feeding, because of the disease, the appetite of the fish will decrease, or even not eat at all, at this time feeding not only does not help, but will pollute the water, which is not good for the fish, so it is best to stop eating for a period of time, and wait for it to feed later.

It's white spot disease.

Due to the large temperature difference between day and night, tropical fish in tanks without thermostats are most susceptible to white spot disease. White spot disease is also known as small melon worm disease, after tropical fish get this disease, first grow small white spots on the gill cover and each fin, and then grow all over the body, and the mucus on the body surface increases in the later stage, and the white spots become white cyst bubbles, which seem to be covered with a layer of white membrane. Diseased fish tend to be significantly less active, floating on the surface of the water or congregating in a corner, and if not timed**, they will gradually lose weight until they die.

The melon worm is a parasite, which likes to parasitize the surface of the fish body when the temperature is 10-20 degrees Celsius, so it is most prone to disease in spring and autumn, with strong seasonality. It is very simple to deal with white spot disease, in addition to the drugs that are sold in aquariums to treat white spot disease, you can also use economical, simple and effective methods.

According to my experience, the general breeding of tropical fish tank, only need to adjust the temperature to 30, 3-4 days later, the white spot will disappear naturally, this is because in the water temperature above 28, the small melon insect can not develop and grow, according to its short life cycle, will be able to eliminate the hidden danger of white spots. But if it is an aquatic plant ecological tank, the water temperature of 30 will be unfavorable to the growth of aquatic plants, at this time, methyl blue and malachite green can be configured in water according to 1:1, drip into the fish tank, so that the water in the fish tank is slightly blue, and it can also kill small melon insects for 2 consecutive days, methyl blue and malachite green have no effect on nitrifying bacteria, and will not destroy the circulating filtration ecosystem of the fish tank, and after 1-2 days, the micro blue in the water will disappear by itself.

To prevent the occurrence of white spot disease, the key is to control the water temperature, do not let the water temperature drop below 22-25, especially in spring and autumn, we must pay attention to keeping warm at night.

Is it white or white spots? If the whole body is not necessarily sick, for example, parrot fish will be like this, just feed the red feed, and the white spots can be warmed for 30+ 2 days.

First of all, there are two possibilities for the growth of bubbles on the body.

1: Your oxygenation system is too powerful, which directly leads to bubble disease in the fish body, which is very popularly said that the aeration equipment in your tank sprays too many bubbles, and the fine bubbles adhere to the fish body, resulting in **inflammation. This is usually only available to large fish.

2: You read it wrong, it's not the bubble but the location of the spores of the melon worm.

If there are no flocculent filaments on the white spots on the black skirt fish, there are a large number of white spots (strong worms of small melon worms), and there should also be on the tail. It is normal for a black dress to change color as long as it is sick or frightened.

White spot disease is contagious, and if you don't get it right, it will cover the whole cylinder.

**Method: Considering that you are a small fish in the tank, the current water temperature can only be 30 degrees, stop feeding, use white point net + malachite green or methyl blue + sterilization water, and administer medicine daily. Salt is placed in the tank. Change the water every day 3 1 with the dried water, pay attention to the temperature of the new and old water should be the same (the temperature of the new water can not go up, you can heat it to 30 degrees on the stove, don't boil it) 3 days to be effective, within 7 days**.

If there is only a black skirt and Mary fish in the tank, it can be dosed, and if there is a fish of the lamp family, it is a problem, and the lamp fish are not resistant to many drugs (if there is, nitrofuracillin + methyl blue can be used, and it can be separated below the standard measurement of 3 1).

I hope it can help you, and I hope the little fish can be ** as soon as possible. . . If you have a problem, you will be secreting me directly...

This is white spot disease, also known as small melon worm disease, the weather is cold and the fish will generally get, slightly raise the temperature to 28 themselves will be good, serious to add a special ** white spot disease medicine.

What is the reason for this? Most of the water temperature is the water temperature, and the color of the black dress will become lighter as soon as the water is changed or frightened. You must have just bought it or just changed the water! It is often said that there is a phenomenon of color loss, and the temperature of the water, the water quality.

Most of the fish have a lighter belly, generally milky white, commonly known as "fish belly white"; The color of the back is relatively strong, such as black, dark gray, grass green or russet. The color of fish with a strong back and a light belly plays a very important role in its life to hide itself and avoid predators. In zoology, this phenomenon is called "protective color".

Fish can also adapt to different environments and have different colors, making their body color similar to their surroundings. In particular, the fish in the tropical seas are even more colorful and dazzling. For example, the peppercorn bream, which lives in seaweed bushes, has blue stripes and green spots on its body.

Some fish near red coral reefs have dark red bodies.

The body of the glass fish moving in the clear water is almost completely transparent, and even the bones and internal organs in the body can be seen. Flounder, which crawls on the sediment of the seabed, has a russet body.

Why do some fish have a particularly bright color, while others change color? This is because the dermis and scales of fish have pigment cells, which include red, orange, yellow, black and other pigments. These pigments can be mixed to form many different colors, giving the body a vivid color, with spots or stripes of different sizes, etc.

In the fish pigment cells, there is also a kind of "silver light" cell called struvin, which is mixed with the pigment cells to produce pigment, which can make the fish's ** sparkle and radiate a dazzling light. At the same time, due to the expansion and shrinkage of pigment cells, the color of the fish changes.
