Cockerels are specific pets. Their tropical origin creates problems for aquarists in caring for them.
Monitor the condition of the pet, to protect from diseases and manifested diseases cockerels.
Symptoms of diseases are associated with deterioration of appearance, impaired visual, olfactory functions, problems with the gastrointestinal tract, impaired motor functions and the respiratory system.
- If the symptoms manifested in all inhabitants at the same time, then the problem is usually in the environment: poor quality water, lack of oxygen in the water, low temperature, nitrates.
- If the problem affects only one species and the other does not, then infectious diseases develop in the aquarium.
- If one inhabitant is sick, then there are problems with physical, mental illnesses, old age, injuries.
Conduct a thorough examination of the diseased, check the water parameters and move the diseased representatives to the quarantine tank.
The most common symptom of the disease – the cockerel fish lies on the bottom.
- Old age.
- Cool water lowers the activity of tropical fish, because of which they fall into a hindered state: they no longer respond to food, is in one place, the cockerel lies at the bottom and breathes heavily. The lowest acceptable threshold for tropical inhabitants is considered to be a water temperature of 19–20 degrees.
- If the pet is breathing heavily and lying at the bottom after moving, moving to another, unfamiliar environment, new aquarium, to other inhabitants, then this is completely normal. Just a cock under stress. After acclimatization after a while the cockerel will become active again.
- But the symptom, when the inhabitant breathes heavily, lying on the bottom, there are more dangerous reasons. One of them is chemical poisoning of the body. Check the indicators of water with the help of tests, move the inhabitants to a favorable environment.
- Dropsy – swollen body.
- Fin rot – white bloom on the fins, their rot.
- Ichthyophthiriosis – white spots on the skin.
- Oodinioz – red plaque and spots on the skin.
- Gill flukes – the gills are covered with mucus, parasites are visible.
- Exophthalmia – bulging eyes.
- Zaprolegniosis – white fluffy coating on the head, body, tail, similar to mold spores. Treatment baths with salt and malachite green, antibiotics.
The course of treatment depends on the symptom-causing illness. For prevention, they feed the fighting fish 2 times a day in small portions, replace water, disinfect the new soil, do not overcrowd the aquarium.
Lack of appetite is not always caused by disease. The safe reasons are the rejection of a single type of feed by a cockerel (most often this happens with dry feed).
In this case, try replacing the usual feed with live: brine shrimp, bloodworm, pieces of lean fish, squid. Another such reason is feed particles that are too large and cannot be swallowed.
It is also normal that the cockerel does not eat after changing food or feeding with an unsuitable type of food (for example, if you do not feed predators with live food) or resettlement in an aquarium. Many species of fish do not eat during spawning and caring for fry.
If the cock takes food particles in his mouth, but then spits it out, does not swallow, then something is probably stuck in her throat. Usually it is a big lump of food, a particle of soil, a foreign object.
Catch and inspect the pet, it is advisable to call the vet.

A sharp loss of appetite indicates a possible constipation, especially if accompanied by a lack of excrement. But adult inhabitants are able to cope with it themselves, it’s enough not to feed pets for a couple of days.
But fry and pets with low immunity can suffer greatly.
But usually cockerels do not eat and move little due to illness. More often, lack of appetite means infectious internal disorders of the body.
Common diseases of males with no appetite:
- Ichthyophthiriosis – a disease caused by the type of ciliates, is detected when white spots appear on the pet’s skin.
- Trichodinosis – a disease caused by parasitic infusoria. Malachite baths with high temperature and aeration help.
- Mycobacteriosis is an infectious disease that affects cockerels and humans. Antibiotic treatment.
Not always a symptom of cockerel fish disease. The most common cause is overfeeding a pet. Males are voracious, so they easily overeat.
Feed them need 3 times a day. If you feed live food, the amount of food for one complementary food is not more than 3 moths per inhabitant.
About the amount of feeding with flakes and granules there are instructions on the package.
One of the causes of bloating in the rooster is the spawning period. The sides and stomach of the females are rounded.
Especially often, swelling precedes dropsy when the internal fluid fills the entire body.
Another common cause is a settlement in the body of tapeworms, due to which the belly of the rooster swells. Special treatments are used for the treatment, which the inhabitants swallow.
The probability of an internal tumor is high. Most often, these inhabitants can not be saved, especially in the later period of the disease.
Vibriosis also causes swelling of the abdomen. It is caused by vibrio bacteria. The disease is usually transmitted in salt aquariums, but in freshwater reservoirs the bacteria survive.
Treated with antibiotics.
The adhesion of the fins and tail indicate the wrong content of the rooster or internal disease. Most often, adhesion of the fins indicates the onset of the disease ichthyology or fin rot.
Treat them with antibiotics and baths with edible salt or malachite green.
Causes of tail dissolution are divided into mechanical and caused by the disease. Mechanical damage is determined by observation of life in the aquarium.
Some inhabitants are not advised to keep with owners of lush fins like cockerels, because they bite and pluck them. These are small species, not necessarily aggressive and territorial.
From overcrowding aquarium inhabitants become nervous. Some fighting fish even bite themselves by the tail, perceiving it as an enemy.
Biting off of the fins usually ends when a separate reservoir is selected. To fight a fish was not boring, a mirror is installed in the aquarium, then the pet flaunts in front of the virtual enemy.
Still plant thick vegetation and sometimes rearrange the decor in the aquarium so that the pet can explore new places.
Peel off the tail and fins with improper care of the cockerel. The fish is sensitive to water parameters, temperature, chemical composition.
The cockerel is able to live in inappropriate conditions and small volume, but only for the period of transportation or movement.
Beautiful tail and fins indicate health, and in case of overcrowding, low temperatures, the tail will climb hard water.
Another reason for fin and tail peeling is fin rot.
Swelling of the gills usually does not pose a serious danger in the form of a symptom of any disease.
- The cockerel flaunts in front of his rival, expecting the other to chicken out and swim away. Thus, in a flock, a hierarchy is formed with a strict definition of places for each inhabitant. The cockerel inflates the gills before a fight to appear bigger and stronger.
- The fighting fish inflates the gills during the breeding and spawning period to impress the females with their dimensions and bright colors. And females already choose the most beautiful male for continuation of the race.
- Feeling unwell. This is manifested not only in swollen gills, but also raised, ruffled scales, passivity, lack of appetite. Usually such a condition indicates a bacterial or viral disease.
Contrary to popular belief, swelling of the gills of a rooster does not indicate a lack of air in the water and does not oblige to buy a compressor to enrich the water with oxygen. Males belong to the labyrinth fish, which are characterized by the ability to breathe atmospheric air.
Therefore, additional aerating devices do not need anything for them; on the contrary, they will harm a rooster that does not tolerate water currents.
- Fighting and active pets constantly want to explore new territories and places, so they tend to leave the aquarium. This is more characteristic of species found in the upper layers of the water in the reservoir.
- More attempts to leave the aquarium are conditioned by fear and stress. Fish are frightened by sudden on / off lights, loud noise, strikes against the glass of a tank with inhabitants, finding a number of large animals (cats) and they accidentally jump out of the water in an attempt to hide.
- The poorly chosen form of the aquarium also contributes to attempts to escape from the water. Rounded shapes enhance external sounds and fish experience stress and nervousness.
- The lack of space or overcrowding of the aquarium makes the fish jump out in search of a place to move and swim.
- Dirty water worsens a condition of fishes, and they try to leave in more favorable environment.
- Disruption of electrical equipment leads to a leakage of current, which is manifested by electric shocks of fish, and the man himself will not even feel them.
- Large and predatory, carnivorous fish scare smaller creatures, and they tend to leave the dangerous territory.
- Incorrect water change in the aquarium. It is impossible to replace all the water at once, the fish gets into a completely unfamiliar medium with a new chemical composition and is under severe stress. Trying to return to the old water, the fish jumps out of the water.
- Parasites irritate fish, interfering with their normal life. For treatment, use drugs against endo- and ectoparasites.
If the color of a bright cockerel suddenly began to change, become discolored and some parts of the body turned white, then this is not a symptom of the disease, but a completely harmless mutation. In some selections, fish with this feature are rejected, but partial white coloring does not affect the health, behavior, and ability to reproduce the fish. The whiteing of the cockerel is only a result, a consequence of many crosses and selection, in which the goal was to bring out new colors by suppressing some genes.
But some representatives of these suppressed genes appear. One of them is the marble gene, which is responsible for the sudden change in the color of body parts with white.
The whitened cock does not need treatment, sometimes the marble gene is again suppressed and the original color of the fish returns.
The clouding or protrusion of one or both eyes in a cockerel fish is a consequence of improper care of the inhabitants of the aquarium. The water in these tanks is dirty, muddy, they have a high content of chemicals that appear during the decomposition of food debris and fish excrement.
First, check the quality of the water using tests for nitrates, nitrites, ammonia. Replace ¼ of the water with clean and separated water.
Do not forget about the temperature difference, which also lowers the immunity of the fish, which contributes to the further protrusion of the eyes.
Blurred eyes are still a consequence of incorrect indicators of acidity, hardness. For roosters, acidity is considered to be the optimal conditions for keeping – 6–7.5 pH, hardness – 5–15 gH, water temperature – 27–31 degrees.
High likelihood of the disease is microbacteriosis or otherwise fish tuberculosis. All fish are carriers of this disease, but it only affects the body when conditions are poor and the rooster is low in immunity.
If the fish is sick, then they treat it with antibiotics.
Another eye bulging indicates aeromonosis, pseudomonosis, which have similar manifestations. Eyes bulging is the first of the symptoms, so there is a chance to cure the fighting fish with medicines.
On the body of the fish appear large spots of different colors: white, gray, red, black. This usually indicates a bacterial or fungal disease.
But rubella disease or spring viremia is especially common with this symptom. It manifests itself at any time of the year.
The incubation period of the disease is a week. The disease is quickly transmitted from one fish to another.
Red spots are localized around the head and fins in front of the body. On multi-colored and brightly colored fish, the spots are easily overlooked, they are especially clearly seen on white representatives.
To cure a rooster, consult a veterinarian who will prescribe pills or antibiotics. But sick fish, especially if spring viremia has progressed greatly, are difficult to cure, stopping the spread of the disease becomes the main task.
After curing the fish, the aquarium, the soil is treated and disinfected.
Spots are a sign of spring viremia, ichthyoftyriosis and oodinosis. But in this case the spots are small, and their colors are white or golden, depending on the disease.
Another sharply arising fish spotting indicates poisoning by nitrogenous compounds in water. Make water tests and replace ¼ of the volume of the aquarium with fresh one.
Irrigation of scales is one of the symptoms of a representative’s poor state of health, usually the fish cannot be helped, because this means a long-term development of diseases. Disheveled scales are closely related to edema. Usually, the scaling scales means that soon the body of the fish swells from the internal fluid, and this is a symptom of kidney failure.
Without the proper functioning of the kidneys, the fish do not live long. Therefore, disheveled scales must be recognized and acted upon. To do this, during the daily inspection of fish, you need to inspect not only the fish on the sides.
Open the lid of the aquarium and view the inhabitants from above. This increases the chance to recognize the flaking of scales before dropsy.
The cause of ruffled scales are bacteria and viruses that have penetrated into the body of the fish and are already breeding inside the body. For the treatment using antibiotics and disinfection of the entire aquarium. Sick fish are removed from healthy ones.
Healthy and not showing signs of illness until the fish make baths with salt, malachite green.
A safer reason for disheveled scales is ectoparasites that have settled between scales and feed on fish skin and skin secretions. They are destroyed by baths with edible salt.
- The most natural cause of death is old age.
- Strong stress caused by sudden changes in the chemical composition and parameters of water. This includes a complete, rather than a partial replacement of water, in which the cockerel ends up in a completely new environment. Too low temperatures also lead to death.
- Toxins and poisons in water – nitrites, nitrates, nitrogenous bases, ammonium, ammonia. Poisoning by nitrogenous bases is determined by the persistent smell of decay emanating from water and turbidity.
- If you put an inhabitant in the water recruited from the tap, she may die from a gas embolus.
- Unnoticed and untreated diseases such as ichthyophthyriosis, dropsy, oodinia, bone disease lead to death.
What to do if you find a dead fish in an aquarium:
- Remove the dead inhabitant from the aquarium.
- Check other representatives for painful symptoms, all pets must be quarantined.
- Inspect the dead pet, check the condition of the abdomen, fins, eyes, gills, after wearing gloves, because many diseases of underwater inhabitants are transmitted to humans.
- If inflammation, rotting of any parts of the body were found, then check other inhabitants for the same symptoms and select the appropriate treatment.
- Check the water parameters.
Pseudomonosis is especially painful in cockerels, because their fluttering, lush fins become obleshimi, rotting. If left untreated, it completely corrodes the skin of the fin, leaving only the fin rays.
Causes: Fin rot rot bacteria are constantly present in the aquarium and do not cause harm if there is no reason for a sudden development. These include:
- Soil contamination by waste and food.
- High population density of the reservoir.
- Infringement of chemical characteristics of water or biobalance.
- Infections falling with new inhabitants.
- Bad water filtration.
- Lack of cleaning aquarium.
Symptoms: fading, bright color of the cockerel, fins stick together, skin puffs up and peels, cornea is cloudy, ulcers form at the roots of fins, holes appear, the skin of fins decomposes, only rays remain.
Treatment: drugs to combat bacterial and fungal diseases. Baths with edible salt, malachite green, bicillin also help.
Developed specialized drugs to combat fin rot.
Prevention: cleanliness and timely cleaning of the soil, the presence of a powerful filter.
A dangerous disease in fish, referring to the bacterial, but still cause it parasites. Dropsy is characterized by swelling of individual parts of the body or the whole body.
But dropsy is usually considered a symptom for more serious illnesses. The most common are mycobacteriosis, aeromonosis, hexamitosis.
The disease affects not all representatives at the same time – in fish with strong immunity, dropsy may not develop at all. More often the young growth suffers. The first place that affects dropsy becomes the intestines, because bacteria and parasites get through the mouth into the digestive organs.
The excrement becomes unhealthy in color and becomes covered with mucus. Fish is not able to fully digest food, but sometimes it still continues to use it. Other organs are gradually affected.
When the disease reaches the kidneys, and they do not do the work, then the characteristic sign of dropsy manifests itself – the body swells from the internal fluid, provoking a bug eye, lifting scales.
Causes: bacteria, parasites, kidney problems, stress for a long time, sudden and frequent temperature changes, poor quality food, mainly from warm-blooded meat.
Symptomatology: swelling of the abdominal cavity, peaking eyes, mucus in the excrement, white mucous pieces of the intestine protruding from the anus.
Treatment: drugs and feed, depending on the cause of the disease.
Prevention: maintaining the purity of the aquarium, maintaining immunity, varied diet.
Aquarists refer to exophthalmia or straggling as a separate, isolated disease, as well as one of the symptoms of more serious diseases. Most often caused by parasitic in the body inhabitants, infection.
Usually manifested with dropsy – the accumulation of fluid in the insides of the fish.
During exophthalmia, fluid accumulates behind the eyeball and gradually penetrates the eye itself. Both one and both eyes can suffer.
Causes: bacterial diseases, infection, fungal diseases, insufficient amount of vitamins in food due to monotonous nutrition, abnormal physiological processes, viruses, eye trematodes. Poor water quality, chemical additives, nitrates, toxins help the development of the disease.
Symptomatology: turbidity of the eye shell, one or both eyes bulging, maybe even falling out of orbits. Appetite worsens, fish activity decreases, cowardice and photophobia appear.
Treatment: establish the causes of the disease: infection, parasites, viruses, bacteria and get rid of the cause of the disease with the help of drugs. When the cornea is clouded (which indicates a poor-quality composition of the water), replace part of the water every 2 days.
Prevention: Timely cleaning of the aquarium.
Ichthyobiasis or bone disease (outdated name) causes a unicellular ichthyobodus – flagellate parasite. Especially often affects young fish, which are prepared for sale – because they live in cramped conditions. Quickly transmitted to all fish of all kinds.
Adult fish suffer less frequently, but they tolerate ichthyobodus and infect others on contact. These parasites are hardy, it is rather difficult to recognize and destroy them, because they tolerate low and high temperatures and are indifferent to the acidity of water.
It is difficult to save fish with ichthyobiasis.
Causes: caused by parasites when sharing diseased fish that have not passed quarantine, feeding infected and unprocessed live food, non-disinfected soil.
Symptoms: the cockerel experiences severe itching of the skin, so it begins to rub and itch against the walls of the aquarium, plant stalks, and stones. Motor functions are disturbed, the fish swims not smoothly, but makes sharp, angular movements.
Often swims not head forward, but sideways. On skin appear blue-gray spots of medium size. The fish feel choking and lack of oxygen due to accumulation of mucus on the surface of the body, gills, fins.
Lack of appetite.
Treatment: immediately after the discovery of ichthyobodose, prepare a tank for a salt bath. Per day put there sick fish 3 times for 10 minutes.
Salt concentration: 1 teaspoon edible salt per liter of pure water. Strengthen the action of salt with the crystal of potassium permanganate.
Prevention: quarantine for purchased fish.
Common aquarium fish disease. In another way, columnaria is also called an oral fungus, because the external manifestations of the disease are similar to a fungal infection.
Causes: The causative agent of the disease – bacteria that live in freshwater tanks. Often they are found in tropical fish species, because for successful reproduction the bacteria require a high temperature, which is present in tropical representatives. They are especially active in cramped conditions, where bacteria are quickly transferred when fish come into contact.
Therefore, a small aquarium or overcrowding, uncleanliness of the aquarist and contamination of the aquarium with waste and food leads to the creation of a favorable environment for the development of columnaria. Another reason is the lack of oxygen in the water, which often happens if the filter does not work well.
Symptoms: detachment, detachment from the outside world, the fish do not perceive the outside world. A cockerel spends a long time in one place (usually clogged up in shelter or vegetation) and does not float.
On the head, lips, in the area of the mouth, gills, fins gray-white spots are formed, similar to cotton wool, fluff. If there is no treatment at the site of white spots, the bacteria corrodes the skin and muscles, and the gills decompose.
Treatment: helps to reduce water hardness and acidity. Help bath with salt and antibiotics.
Prevention: Do not allow overpopulation of fish.
Corduroy or oodiniosis or velvet disease is a disease, the causative agent is considered to be the Oodinum parasite. External manifestations of oodinia are similar to ichthyophthyriosis, but the difference lies in the color of the tumors on the skin.
With ichthyophthiriosis, they are white, while with oodinia they are yellowish.
Infection and development of the disease passes quickly. If you look at the moment of the first manifestations of velvet disease, then the fish will be difficult to cure, sometimes even impossible.
Causes: overcrowding, high water temperature, lack of cleanliness of the aquarium.
Symptomatology: small nodules resembling golden dust or flour are formed on the body and fins. The behavior of the fish varies: some swim nervously, rub against the walls and plants because of the itching of the skin, others are sedentary, they are long in one place in the shade.
In males, long fins due to mucus stick together and hang as a lump. Later, the skin of the fins between the rays rot.
Parasites increase the secretion of mucus, which causes lack of air, asphyxiation.
Treatment: sick fish are transplanted into a separate tank with a temperature of 26 degrees. They are treated with a solution of malachite green or trypaflavin, and then fed with live food in small quantities. Then the next day, process the copper sulfate and raise the temperature to 30 degrees.
Handle all inventory and aquarium.
Prevention: maintaining the purity of the aquarium.
Ichthyophthiriosis is a fish disease that causes ichthyophthirius by ciliated infusoria. In large reservoirs, where there is a constant change of water, the disease develops poorly, but in closed systems, especially in aquariums, ciliates quickly infect all inhabitants.
Aquarists often believe that these ciliates live in any water and the fish organism can easily cope with them. But this is not the case – the ichthyophthiriuses enter the new environment by means of settling new fish, decor, and unsuccessful sterilization.
More often carriers of ichthyophthirius become representatives with a light color, since they do not show the symptoms of parasites.
Causes: lack of quarantine for newly purchased fish, lack of disinfection, untimely cleaning of the aquarium, pollution, overfeeding, high density of fish in the aquarium, low temperature.
Symptomatology: on the body of a fighting fish, white spots of ichthyophthiriosis appear, which look like semolina granules. Sluggish condition, lack of appetite, difficulty breathing, itching of the skin.
Treatment: for the destruction of parasites on the surface of the skin of fish that live in the water column, help drugs that have a strong effect, but do not affect the fish. Even ichthyophthiriuses do not like high temperature, so 35 degrees will shorten the life cycle of parasites and kill them.
Prevention: all new fish are quarantined, cleanliness is maintained in the aquarium.
A small fish that has become ill with gill flukes or monogenes, which were not found in time, is killed by insufficient air or asphyxia.
Reasons: the relocation to the aquarium of a new fish of exotic breeds, which were recently caught from the wild and did not conduct quarantine. Rarely there is an infection with unprocessed live food.
Symptomatology: the skin and gills of the rooster are covered with thick mucus, which interferes with breathing, the color fades, the body swells, the gills bulge to the sides. Still there is swelling of the gills. The patient refuses to eat, spends all the time lying on the bottom.
Rarely, an aquarist himself can see gill flukes when they are large in size and protrude from the gills due to lack of space.
Treatment: to get rid of gill flukes, effective baths with formalin, potassium permanganate, very weak ammonia, chlorophos and karbofosom. Feed the fish rarely and in small portions.
Diseased sick fish in a separate container to prevent further spread of the disease.
Prevention: feed frozen and not live food, keep the aquarium clean, change part of the water every week, monitor the water parameters.
Many pathogens of dangerous diseases all the time in contact with fish, live in the same environment and do not manifest themselves for no reason. Therefore, treatment of diseases of cockerel fish is not required if they are prevented with the help of prophylaxis.
- The best preventive measure for all diseases is to keep the aquarium clean. In the polluted tank, pathogenic bacteria and viruses actively proliferate.
- Knowledge of optimal conditions for keeping cockerels. They have limits in care, outside of which they feel bad and sick. This particularly applies to the temperature of the water, to the testimony of which the roosters are particularly sensitive: sudden drops in fish cause stress and reduce immunity.
- The parameters of water, acidity, gases, hardness, chemical indicators strongly affect the health and health of fish. These parameters the aquarist should follow to keep them at an acceptable rate.
- Quarantine is required for all purchased fish. New inhabitants can not be run into the aquarium until the monthly quarantine is over. And only after you are convinced of the health of the fish, it is launched to other inhabitants.
- Disinfection of new elements of decor, soil, artificial plants is required.
Diseases of fighting fish are difficult to recognize without the experience and knowledge of a veterinarian, but according to the symptoms, even a beginner aquarist is able to recognize the disease and help the pet in a timely manner. But it is better not to bring the disease at all, maintaining the necessary balance and cleanliness in the aquarium.
