The situation when there is a noticeable semolina on the fish in the aquarium, is unpleasant and requires prompt action. From this point on, we can assume that the aquarium has abandoned well-being. All residents of such a water home are at risk of disease.
We vainly begin to think about the cause of what happened, feverishly read tips in literature and the Internet, and, most importantly, take urgent measures. Here it is important to find a competent solution and get rid of the problem to the end.
The manka on the body of a fish is a disease caused by the smallest fish parasites – ominous ichthyophthirius. To date, there are many opinions about the classification of ichthyophthirius.
They differ in the shape and size of the cell nucleus, as well as other biological properties. But one thing remains constant – for the life of parasites a tissue substrate of fish is necessary.
It is in it that the cyst germinates, matures, increasing in size, matures and separates as it finally forms.
What happens to the fish in this situation? It is covered with small white dots.
Her movements become abrupt and erratic. Sometimes she tends to rub on a hard surface. Often hiding in the undergrowth.
The fins sometimes stick together and look pitiful. The appetite of the fish is practically absent.
Such fish have a miserable appearance and require urgent treatment.
The disease of one fish is unpleasant. But the danger consists in the following: the cyst, detached from the body, is the place where several hundred future ciliates are concentrated. They, easily moving on water, reach the body of healthy fishes, penetrate into its upper tissues and form pustules.
Another name for such formations is dermoid tubercles. In them, the process takes several days and ends with the formation of the same cysts, which is subsequently separated.
So we answered the question: where did the white bulging dots come from on the fish?
If you do not take timely measures to destroy the ciliates and disinfect all that is in the aquarium, living things can die.

Like any parasite, ichthyophthirius cannot exist without a host organism. Water is only a way (factor) of its transfer from one individual to another. Therefore, the parasite can get into a healthy aquarium environment in several ways:
- with diseased fish (perhaps, during the period of purchase there were no obvious manifestations of the disease – the so-called “incubation period”);
- with water containing cysts;
- with plants, if they recently grew in an infected aquarium;
- with live food obtained from an aquarium in which such pathogens were present.
Unlike fish covered with white tubercles, pathogens are not visible in the water and on plants. Therefore, this factor is more dangerous.
Thus, ichthyophthiriosis – ciliates ichthyophthirius in action.
Fish with ichthyophthyriosis are weak and not immune to other diseases. Their condition often worsens when joining a bacterial or viral infection.
In this case, inflammation and intoxication are added to the symptoms of ichthyophthiriosis.
It is equally important to make a diagnosis right away. At first, the disease can be confused with fungal lesions (for example, ringworm).
However, in this case, over time, the points will acquire fluffiness (can be seen in the photo).
White dots are also the first symptom of lepidortosis symptoms. True, its formations are pustules with a liquid content.
Correct diagnosis is a guarantee of timely and effective specific treatment.
The first step, which aquarists go to, is to heat the water to 28-32 ° C. At the same time, ordinary table salt is added to the water.
Its amount is calculated from the proportion of 2 g of salt per liter of water.
The exposure time of these factors should be at least a week.
At the initial stage of pathological processes in the aquarium, the method can help. True, many argue that this applies only to certain ichthyophthirius that are sensitive to salt and temperature increases.
The second most popular home treatment can be considered the addition of chemicals. Copper sulphate, malachite green, methylene blue (blue), formalin, potassium permanganate, furatsilin: ichthyoftiriosis can be defeated. But do all other inhabitants remain viable: plants, snails, shrimps and others?
It is better to think about it in advance.
How else to try to treat?
Sometimes with tropical fish, ichthyophthirius resistant to furatsilin, bicillin, furazolidone are imported to pet stores.
Symptoms of “decoys” in fish continue to develop, despite the rather high concentration created in the water. How to treat then manifestations of ichthyophthyriosis?
Today, Antipar is considered an effective tool. It has antiparasitic properties, a powerful antibiotic and antifungal composition.
In parallel with ichthyophthiriosis, it is possible to get rid of secondary bacterial infections.
The liquid is characterized by a blue-green color and a specific odor. This is due to the presence of malachite green and formalin.
Additional components in the medicine help the regeneration of the skin of the fish, the normalization of their overall condition. An aquarist seeking to cure fish completely must tune in to repeated treatments, at least twice every other day.
It is necessary to add means at the rate of 1 ml per 10 liters of water in the aquarium.
A similar composition at the means of Sera Costapur. Its concentrate character makes the product more economical. A 50 ml pack is enough to disinfect an 800-liter aquarium.
The German manufacturer made sure that the tool does not possess the poisoning ability of the fish.
People often ask: is it possible to effectively sanitize an aquarium after evicting fish with ichthyophthiriasis? Having removed all inhabitants from the aquarium, thoroughly washing out the internal surfaces and pouring in fresh clean water, it can be disinfected for preventive purposes.
To do this, add 3-4 drops for every 25 liters of water. In this case there is a condition: filtering or aeration should not be carried out.
Exposure (exposure time) must be maintained according to the manufacturer’s instructions in a calm state. The introduction of the composition must be repeated on the third day.
Among professional aquarists and lovers high authority has another tool – Tetra ContraIck plus. Multipurpose tool.
It helps to disinfect the aquarium from many pathogens, including ichthyophthyriosis.
According to the description, its composition does not have an aggressive effect on the biocenosis that has developed in the water house.
The advantage of the drug is a short period of exposure. Already on the fourth day, the situation will improve a lot, and in a couple of days the well-being will fully recover: the aquarium will look like before.
With the manifestations of semolina on the body can be dealt with the help of “Delagil” and “Yodinola” Before you process the aquarium, you must read the instructions. Despite the fact that they are considered safe in relation to fish and plants, sometimes the fish fins begin to collapse (they are later restored).
Feed in such periods aquarium residents should be less, as their appetite decreases.
Iodinol, in addition to the described properties, helps to cope with iodine deficiency and has regenerating properties that accelerate the healing process of wounds on the body. There is information about the use of this medicine during spawning.
Disinfectant properties positively affect the quality of eggs: they do not form rotten areas and there are no signs of poor quality.
Means inert to increase the hardness of water, their re-introduction into the water has an accumulating effect.
Having noticed the “semolina” on the body of the fish, it is impossible to delay. Many, especially if there are fry in an aquarium, prefer to wait or use gentle home-made techniques.
This plays into the hands of parasites: they are given the time needed for reproduction. One sick fish in a few days can infect a dozen living nearby. Experienced aquarists advise: immediately buy professional tools and act according to the instructions.
If you have not managed to seed fry, it is better to donate them for the overall health of the water house. Proper and timely treatment is the key to a positive outcome in the fight against ichthyophthyriosis.
