The aquarium fish swollen belly: a reason and what to do?
Bloating in fish is very exciting for many owners of home aquariums, especially at the initial stage of breeding pets. Then the aquarists worry about the slightest external changes or changes in fish behavior. The most common problem of aquatic life is bloating. The reasons for its appearance can be both bad and good, so you should learn to distinguish between them.
The disease - "abdominal dropsy"
This disease has some hallmarks. The main one is tousled scales, from which the fish resembles a pine cone. Also, the fish has rapid breathing, weakness and dullness of the color. The disease occurs as a result of viral or bacterial infections, and also occurs with the disease hexamitosis. Old individuals are susceptible to dropsy, weakened fish or fish with obesity. Unfavorable conditions, frequent stresses also contribute to the infection of aquarium fish. In order to prevent dropsy, it is advisable to keep the fish in optimal conditions for them, moderately feed them with high-quality and varied food, but keep new fish in quarantine.
The appearance of caviar
This is perhaps the most pleasant and harmless reason for bloating the abdomen of a fish. In the stomach of the female, caviar forms and develops, due to which the stomach can become quite impressive.
What to do: be patient and wait for spawning, while properly caring for the expectant mother.
Some fish swallow large chunks of food, which can then be in their body for up to several days, inflate their bellies and cause digestive upset. To prevent this from happening, crush the food into smaller pieces.
Food insecurity leads to the appearance of obesity in fish, as a result of which their stomachs again swell.
What to do: unfortunately, nothing can be done here, in 99.9% everything ends in death.
Such fish often suffer additional abdominal dropsy during life and cannot reproduce due to obesity of the ovaries and testes. And the advice can be only one - do not overfeed.
Gastrointestinal tract inflammation
If the fish confirms inflammation of the stomach and intestines, then this indicates a lack of various feeds. Symptoms of this disease in aquatic pets:
- Darkening color of fins and body.
- Loss of balance.
- Change in excrement.
- Swelling of the abdomen with a good appetite.
What to do:
To prevent this disease, it is worthwhile to reduce the consumption of dry food by fish. It is recommended to do their washing, soaking, disinfection of bloodworm and tubule, diversify the diet.
Inside the body of the fish, a tumor appears and begins to grow, inflating the abdomen. Genetic characteristics or external factors (the effect of "chemistry", radiation, etc.) can cause it.
What to do: unfortunately, nothing can be done here, and most often such fish are disposed of.
You can bring them into the aquarium with live food, but this rarely happens. Most often they do not bring harm. But if there are too many of them in the fish’s body, then everything can end with its death.
What to do: treat drugs for worms that are sold in pet stores.
Its causative agent is the vibrio bacterium. The disease affects fish that live in salt or brackish water. However, bacteria can also enter a freshwater home pond with seafood feed.
At risk are all fish that have poor living conditions and weakened immunity.
The disease can occur acutely or chronically and is manifested by lethargy, apathy, rapid breathing, desire to retire, subcutaneous hemorrhage, change in fin skin on the back, tumors, ulcers and so on, including bloating of the abdomen.
Often, vibriosis is confused with other infectious sores, and only a laboratory study can reveal the truth.
What to do: quarantine and treat with antibiotics, nitrofurans and sulfonamides, adding them to water, as well as chloramphenicol (for food). All drugs are purchased at the pet store, and the dosages and treatment time are indicated in the instructions for them. Prevention consists in careful care, disinfection of water and feed, control of nitrates, nitrites and ammonia in water.
This disease affects cichlids of water bodies in East Africa. It was first discovered in fish from Lake Malawi. Symptoms are similar to dropsy, but this is a completely different disease. Little investigated.
It can be identified by lethargy, loss of appetite, shortness of breath or rapid breathing. At first, the fish stays at the surface of the water, but during the day the abdomen swells greatly and it can no longer swim, it lies at the bottom. Death occurs after a maximum of three days.
The causes of the disease are considered to be poor quality water, the presence of sodium chloride in water for a long time, and a diet consisting only of dry feed and mammalian meat.
What to do: eliminate the causes of the disease. You can try to cure antibiotics with a wide spectrum of action, but their effectiveness has not been proven.
Fishes most often die, before suffering, therefore, most often they are euthanized.
If the breeder has an unsuccessful conclusion to the fry, then they may have an enlarged abdominal cavity. Such individuals are not considered harmful or sick, but simply inferior.
Tips for aquarium owners!
- Slow bloating of the fish abdominal cavity can occur due to obesity, the multiplication of tapeworms, or tumor-like neoplasms.
- Rapid bloating if the health of waterfowl is affected by bacteria or poor aquarium conditions.
After the death of an individual inside the aquarium, fermentation of its abdominal cavity occurs, as a result of which it increases in size, but this is not the cause of the death of the pet. To minimize the risks of bloating the abdomen of fish, you will need to create the most favorable conditions for them, proper nutrition and only healthy new roommates. In this case, a home aquarium will delight the eyes of its owners for years.
