How to understand that the fish is sick?
All illnesses are either the result of improper maintenance practices or of different infections and parasites getting inside the aquarium.
It is crucial to realize that inadequate care considerably reduces a fish’s immunity, increasing the likelihood of fungus or virus infection.
Most of the time, a quick glance is sufficient to determine whether someone is ill:
- the fish stops swimming, lies on the bottom or becomes inactive;
- sometimes sick Swordtails, on the contrary, move chaotically throughout the aquarium, try to rub against the walls or the ground;
- the individual loses its appetite, its belly swells;
- white dots, spots, a cloudy coating, fluffy tufts appear on the body;
- fins break off or become thinner.
It is preferable to move a fish into a quarantine tank if such symptoms are seen in just one fish.
Fish kept in quarantine are kept for a considerable amount of time in a separate, specially designed aquarium (quarantine tank).
Diseases and treatment: their description and external signs, causes, prevention of a specific disease
Swordtails fall ill frequently, but the most common illnesses are limited to those that are easily treated. Please contact a veterinarian to establish an accurate diagnosis and prescribe the appropriate treatment for fish. The information in this article is written purely for informational purposes and does not carry any recommendations.
What causes sudden death?
Swordtails are known to die suddenly and mysteriously, according to some aquarists. Owners occasionally discover that a fish has stopped eating, and a day later it passes away. The explanation for this phenomenon is straightforward: nitrites, which are waste products in aquariums, cause severe poisoning in pets.
The following are the causes of nitrite buildup in water:
- overcrowding of the tank;
- lack or small number of plants;
- untimely water change;
- poor cleaning (bad filter).
There are more dangerous substances present as a result of all these factors.
It is critical to realize that nitrites are extremely toxic substances that are bad for swordtails.
Further oxidation transforms nitrites into less toxic nitrates. You must do an instant nitrate and nitrite test on the water if the fish start to die out of the blue. You can accomplish this by buying test strips that require dipping in water and comparing the strip’s color to the scale that is attached.
In order to achieve balanced conditions in the aquarium, you must add fresh water if the indicators are too high.
Long poop
The long, thread-like feces that swordtails produce—up to 4-5 cm—are frequently noticed by aquarists. Since the fish’s digestive system responds in this way to the digestion of dry food, this phenomenon is typically accepted as normal. However, it is advised to vary the diet, as it will undoubtedly not be helpful to maintain on dry flakes for an extended period of time.
It is crucial to pay attention to the type of feces: mucous or transparent feces may be a sign of overeating or digestive tract disorders.
Try feeding fish less food and keep an eye on their health. The remaining negative symptoms won’t take long to manifest if the violation is brought on by a bacterial infection. Speak with the veterinarian in order to provide a precise diagnosis and treatment plan for your pet.
Why lies at the bottom of the aquarium?
Swordsmen may drop to the bottom for the reasons listed below:
- Physical trauma received from an aggressive neighbor or objects in the aquarium. In this case, it is better to inspect the fish and, if necessary, put in a separate container. For recovery, it is recommended to add a little dissolved salt (at the rate of 2 hours.l. salt per liter of water).
- Pregnancy. Before giving birth, females (like other viviparous) often look for a secluded place or lie on the bottom. If you intend to get offspring, then the female should be moved to a spawning tank.
- Overeating. Perhaps the fish simply overate or ate too large food. To prevent obesity and subsequent death of the individual, review the diet.
- Parasitic or infectious diseases. At the initial stages, the usual symptoms (plaques, growths) do not appear, the Swordtail simply loses the desire to move. If the above-mentioned signs join apathy, then the individual must be quarantined and treated with special drugs. To establish an accurate diagnosis, in this case, it is imperative to consult a veterinarian.
- Disruption of the swim bladder. The individual lies on the bottom, and when trying to swim, behaves as if drunk and cannot hold its body.
Even when the water’s parameters change—for instance, when too much fresh water is added or when they are removed from quarantine or spawning grounds—sometimes swordtails lie on the bottom. They will eventually acclimate to the new surroundings and resume swimming.
Fin rot
A frequent infection that typically strikes weak or fry fish.
Since bacteria can affect internal organs (usually the nervous system), treatment should be initiated as soon as possible to prevent a rapid death.
The disease’s initial symptom is clouding of the fins, which quickly worsen.
A veterinarian should also prescribe the necessary medication, which should be administered to all afflicted swordtails and kept in a quarantine tank right away. The fish are kept in quarantine (at least for five to six days) if the treatment is successful.
Semolina
Although Semolina (ichthyophthirius) has not escaped Swordtails, it usually affects fish with compromised immune systems. Small white dots will appear on the skin of the fish if the ciliate has been able to establish itself inside it. The fish will also scratch itself against the walls, the dirt, and any decorations.
A simple method for getting rid of semolina is to raise the water’s temperature gradually to 26 °C (or, if it was already that high, another 2-4 degrees). The rash ought to disappear in a couple of days.
Rare diseases that occur in Swordtails
Swordtails are rarely afflicted with other diseases. Among them, the following stand out:
- "cotton wool disease" – looks like a thin fluffy coating on the body of the fish, which is caused by a fungal infection and usually appears when overcooled;
- columnaris (mouth rot) – a white coating around the mouth, caused by bacteria;
- swelling or clouding of the eyes – can be caused by physical injury, infection or poisoning with nitrogenous substances.
Although swordtails are colorful and well-liked fish, they are susceptible to several illnesses that can harm their physical and general well-being. We’ll look at the top five diseases affecting Swordtails in this post, along with thorough images, explanations, causes, symptoms, and helpful treatment and prevention tips. Whether you’re a novice or an experienced aquarium keeper, knowing these requirements will help you maintain the health and well-being of your swordtails.
In what cases can you treat in a common aquarium, and when is it better to remove a sick fish?
The sick person needs to be kept in a quarantine container if the illness is brought on by a bacterial or fungal infection in order to prevent spreading the disease to other Swordtails and aquarium occupants.
When pet health issues result from disregarding maintenance guidelines, the owner must take care of the fish in a shared aquarium. It is important for new fish to acclimate to the water they will inhabit in the future. Going forward, you ought to offer top-notch treatment.
