Hello dear readers! Unfortunately, we have not yet invented an ambulance for aquarium fish in our country.
Based on this, aquarists themselves learn to treat their pets. In order to successfully confront various diseases and regularly carry out preventive measures, today we will talk with you about the signs of fish diseases and, prevention and treatment methods.
Before detailing the subtle points, let’s first define the non-communicable diseases of aquarium fish.
Since the fish are cold-water animals, the body temperature of the fish depends directly on the ambient temperature, that is, the water in the aquarium. It is not just that they say and write at what optimal temperature this or that fish should be kept.
If the aquarist breaks the temperature, it can lead to negative consequences.
Often, novice aquarists put their cans on the window sills or in the immediate vicinity of the window, from which cold air siphons in winter. This leads to the emergence of simple inmates.
And by the way, this can happen not only in winter. In the summer, when the water warms up well in the sun, at night it cools down and the fish may simply freeze due to the temperature drop to the lower side by 10-12 degrees.
What can lead to prolonged hypothermia? That’s right, to reduce the protective functions of the body. It seems that everything was normal, but at one point the pet refuses to feed, swims near the surface or often heats in front of the reflector.
Body color turned white and fins tucked. Cold water on young animals has a particularly negative effect.
If the fry are kept in cool water for a long time, they can completely lose their ability to breed, but if there is still a progeny, it can all perish.
But the excessively high temperature of the water also negatively affects the health of the fish. With prolonged content in water with high temperature, the fish becomes mature much earlier, and, as a result, it will have weak offspring. Aquarium fish do not hibernate, but if you try to watch a crucian carp or carp while cooling the water, you will notice how they get into anabiosis and bury themselves in silt until it warms.
If you keep domestic fish, they will not have an anabiotic state at a constant temperature of the aquatic environment. However, the chance to get colds is still high. It is not necessary much, it is enough to change 1/3 of the water to a cooler one and voila …
But it is considered extremely dangerous to transfer aquarium fish from warm water to a cooler one or vice versa. With such a transplant, the fish falls into shock: rapid breathing, swims up the abdomen.
If the state of shock passes, then the fish for some time can rush over the aqua and try to jump out of it. As a rule, this disease is accompanied by saprolegnosis.
A gray bloom appears on the body of the fish, brown-white threads may appear from the nose and the fish eventually die.
When transporting fish from the place of purchase to a home aquarium, always monitor the water temperature. It is possible to transplant fish from a purchased vessel to an aquarium if the temperature difference between them is no more than 3 degrees.
The disease manifests itself in the swimming of all fish near the surface, where they greedily try to swallow the atmospheric air. If within 30 days the aquarist does not pay attention to this symptom, then the fish will die to every single one. The main cause of suffocation is a sufficient amount of oxygen dissolved in water.
This is due to excess feed floating in the water, overheating of the water and a large number of plants.
What should an aquarist do in this case with his nursery? First you need to remove from the aquarium all the uneaten food, dead leaves and plant stems and the remnants of various living organisms.
Also, you must reduce the feed and lengthen the daylight hours and turn on enhanced aeration. The increase in the duration of daylight hours is especially important for the winter season.
Among other things, you must adhere to at least the minimum certain standards when planting fish and avoid overcrowding the aquarium. If your snails are very fertile, then lead a constant struggle with them.
Snails are a kind of signaling device. In particular, this applies to sandy Melania, which, when there is a shortage of oxygen in the water, will be selected from the bottom to the walls of the aquarium.
In order not to destroy your fish from asphyxia, it is better to regularly conduct a couple of times a month research of aquarium water on its oxygen content.
In the summer, on warm sunny days, excessive amounts of oxygen can accumulate in intensively aerated water. Its excess can lead to a disease called gas embolism and the death of fish. Sick fish become very restless, jerking fins, rushing around the aquarium and trembling all over.
Look carefully at the gill covers, their movement may be slow or they may stop moving altogether. Also in fish, the lens of the eye may become cloudy, and there is necrosis of the fins, as well as the dusting of the scales.
In this case, the fish need to be transplanted into another aquarium, where the amount of dissolved oxygen in water is not more than 15 mg per liter. In just one hour of time, the fish recover completely.
Obesity occurs when a one-time and very abundant feeding. In fish, the fatty tissue on the abdomen and internal organs begins to increase rapidly. The disease is chronic.
This disease affects fish living in small aquariums, where there is no aquatic vegetation, or if you keep pets only on dry food.
Symptom of the disease is an increase in the anterior part of the abdomen. The liver also increases in volume, the genitals are covered with fatty tissue and hydrobionts become infertile.
I have always told my readers – feed your fish with a variety of food, as this is a guarantee of health. Often come to the mail questions that with the fishes. When we start to figure out what they feed, the answer sometimes kills – only dry flakes.
Gentlemen, it’s also impossible, you eat a variety of food every day. Also should eat and aquarium fish.
This disease usually occurs in fish when it feeds on spoiled dry and live food. Pets will eat it more than willingly, but then problems begin: the fish become lethargic and their color fades, the anus swells up and the belly slightly increases.
Excrement becomes filiform and mucous and blood.
It is possible to establish the diagnosis only when opening the belly. In sick individuals, hemorrhage can be seen (multiple hemorrhages into the abdominal cavity of varying severity).
If you can not avoid the disease, then immediately change the feed. In no case do not use the food for fish, which you mined in reservoirs, where wastewater flows.
A sore can occur if you have kept males and females apart from each other for a long time. As a rule, a cyst is noticed when it is too late. Milk and caviar in mature fish turn into jelly, and the belly at the same time significantly increases in volume, which leads to squeezing of internal organs.
Fish stop eating and eventually die.
It is impossible to cure young animals from such a sore, and in large fish you can try to give out a cyst through the anus. However, after such a procedure, the fish will not live long.
To prevent such a disease from occurring, keep the males and females always in the same aquarium and feed them with various food.
That’s all for today, stay tuned to the news on the blog and do not miss the sequel!
