Dear colleagues! Today we will talk with you about aquarium fish diseases and on the agenda we have fish tuberculosis. The causative agent of this infectious disease is the bacterium Mycobacterium piscium which looks like a fixed stick.
When the pathogen enters, several fish are infected at the same time. The labyrinth, carp, harazinki and tooth-toothed are most susceptible to the disease.
Petsilievye and tsikhlovye less susceptible.
It is possible to bring the pathogen Mycobacteriosis into your aquarium together with the soil, food for fish and aquarium plants. Also carriers can be fish and mollusks.
There are also cases when fish tuberculosis enters the aquarium through insects that crawl into the water to drink water. In addition, fish with weakened immunity and those fish that were kept in poor conditions are very often sick.
It was noted that the causative agent is sufficiently resistant to various acids and the most suitable temperature for its active development ranges from 18-25 degrees Celsius.
There are a lot of symptoms and they are diverse, but in almost all of the diseased fish you can see common signs of this disease: lack of appetite, destruction of fins, lethargy, honebord, blanching of color and eyeballs and loss of scales. In rare cases, infected fish show ulcers and black spots over time.
The above symptoms can appear in a single case, and in all sorts of combinations. More rare fish species may exhibit specific symptoms:
- Macropod may cause reddening of the body or skin damage. The scales will begin to rise due to excessive pressure of fluid accumulating in the scaled pockets. Over time, such a damaged scale will fall. Otherwise, an eyesore or peep eye can form, which further leads to blindness;
- in zebrafish due to fish tuberculosis, eyes may fall out of orbit and the abdomen will increase;
- Petsilievye no longer in contact with other fish of their family and cease to eat. After that, they are waiting for complete exhaustion, their back arches, the belly retracts and bones begin to bulge out from under the skin;
- the skin on the abdomen of the males begins to stretch and after a month or two it becomes completely transparent. This is all accompanied by a rejection of food intake and the fish move in spurts around the pond.
Fish tuberculosis is treatable only at an early stage, that is, until the aquarium fish begins to refuse to feed. Treat fish with tuberculosis need kanamycin, which must be mixed into feed.
The aquarist should prepare a mixture of proportionality: 10 milligrams of kanamycin per 10 grams of fish food. The later stages of fish tuberculosis are not treated, that is, you have to destroy all seriously ill aquarium inhabitants. After that you will need to disinfect the entire aquarium equipment with 5% bleach solution or 3% bleach solution.
For disinfection, you will need to pour a liter of treatment solution into the aquarium and wipe with a rag all the walls of the aquarium, both inside and outside, two or three times a day. Next, you need to thoroughly wash the aquarium and fill it with soil, then plant the plants and fill with water.
That is, to make the launch of the aquarium on the new. And after a couple of weeks, you can run the first aquarium fish.
The causative agent of fish tuberculosis is dangerous both for aquarium inhabitants and for humans. You need to be extremely careful when contacting an infected aquarium.
Do not take water in your mouth and do not immerse your hands in it. Mycobacterium piscium can get into our bodies through a tiny abrasion or a wound. After several weeks, changes in the skin will appear at the site of contact.
Complete healing of the affected skin occurs after a couple of years. If contact could not be avoided, then it is better to immediately consult a dermatologist for treatment.
As I mentioned a little higher, the inhabitants most vulnerable to infection with fish tuberculosis are those who have weakened immunity. In addition, it increases the chance of developing the disease can cause an overpopulated aquarium, poor quality aquarium water and a lack of oxygen.
In order not to encounter this scourge, you need to maintain cleanliness and order in the aquarium, as well as provide balanced nutrition to the inhabitants of the underwater garden. To prevent the development of harmful microorganisms in your tank, use ultraviolet lamps.
