Have you noticed that your aquarium fish's fins have become ragged, as if someone had bitten them? Or maybe they look dull, covered with a white or reddish border? Most likely, you are dealing with one of the most common diseases in aquarium keeping — fin rot.
This disease is most often bacterial in nature. It is caused by opportunistic bacteria that are almost always present in the water. They attack fish only when their immunity is weakened. Cold water, stress from overcrowding, aggressive neighbors, injuries — all of these open the door to infection.
The good news is that fin rot is fairly easy to cure in its early stages. Fish fins have the ability to regenerate. The main thing is to notice the warning signs in time and create the right conditions for your pet to recover.
Fish that can get sick
Pseudomonosis mainly affects barbs, blue neon tetras, goldfish, livebearers, and labyrinth fish. This disease poses a greater threat to young fish. Older fish are less susceptible to pseudomonosis, and the disease is not as severe in them.
The disease poses the greatest threat to fish with fancy tails and fins. Veiltail goldfish are particularly susceptible to this disease. Once the disease has taken hold, it can completely rob these aquarium inhabitants of their former beauty.
Causes of the disease
Causative agent of the disease – aeromonas or Vibrio Pseudomonas bacteria, which are the cause of infectious disease in fish.
Causes of the disease fin rot:
- Infection occurred after using “live food.”
- The disease was transmitted from new inhabitants of the aquarium.
- Fish live in unsuitable conditions (inappropriate water temperature, pH level).
- Stressful circumstances
- Excessive aggression in fish.
- Lack of aquarium care.
For the purposes of prevention you need to choose your fish carefully in aquarium: give preference to healthy, active specimens without any signs of infection. Quarantine must be observed for newcomers. Proper aquarium maintenance is important: adequate aeration, filtration, systematic water replacement, water quality control, and optimal temperature.
Symptoms of pseudomonosis
If fin rot has occurred in a community aquarium, all inhabitants must be treated, even if symptoms are only found in one or a few fish.
The main symptoms of the disease:
- Fin rot is clearly visible on young fish when their pectoral fins and tail fins disintegrate. In adult fish, the disease is identified by the rotting of the tips of the fins, which spreads to their bases.
- The bluish-white tint on the fins begins to cloud over. In diseased fish, the white-blue border becomes larger and covers the entire fin. This is especially noticeable in young fish with semi-transparent fins.
- Red tips and spots appear in the fin area. Blood vessels become blocked, causing the fin to disintegrate.
- If the infection is not destroyed in time, it will spread from the end of the fin to its beginning, causing inflammation and decay. The fin rays fall off and, as a result, the fins become shorter. In fry with fin rot, the fins disappear completely.
- Bacteria cause the destruction of the entire fin. They develop white purulent ulcers. If the fish is not treated in time, the rot will spread throughout the body. Infected tissues will turn pale and take on a pinkish hue. Untimely treatment can also result in the death of the fish.
- The eyeball becomes cloudy.
Fin rot is a fish disease in which the edges of the fins become cloudy, tear, and gradually deteriorate. It most often appears due to poor conditions: dirty water, overcrowding, poor care. The causative agent is a bacterium that easily attacks already weakened aquarium inhabitants. The main thing is not to wait, but to immediately improve water purity, choose the right food and, if necessary, treat with antiseptics or special preparations. The best protection is prevention: a clean aquarium and healthy care.
Treatment
The initial stage of therapy consists of examining and improving the microclimate of the aquarium.
First, you need to:
- clean the filters;
- remove rotten aquatic plants from the aquarium.
- boil the soil, decorations, and net for 15-20 minutes before putting them back.
Next, you need to replace the water. It is better to increase the water temperature to the maximum tolerable for this species of fish.
The main thing is to remember about all the aquarium inhabitants. It may happen that others cannot tolerate changes in temperature. In such a situation, the sick fish can be moved to another place, or you can wait a couple of days without changing the temperature.
If its condition improves, no further action is required.
If raising the water temperature does not help, then medication therapy is necessary. In most cases, in the early stages of the disease, treatment will consist of adding a mixture of a specific element to the general aquarium in the appropriate dose, or giving the fish separate treatment baths.
Fin rot is one of the most common but manageable problems in aquarium keeping. Don't panic if you notice its symptoms in your fish. Timely action is the key to success.
Treatment should always be comprehensive. It is important not just to add medicine to the water, but first and foremost to establish the right conditions in the aquarium. Clean water, proper nutrition, and no stress for the fish often work better than any pharmacy remedies.
Remember that the health of your pets directly depends on regular care and your attention. Observe the behavior and appearance of the fish, react to changes in time, and then many diseases, including fin rot, will bypass your aquarium.
