Fin rot in fish: how to treat?

Almost every aquarist at least once and noticed the symptoms of fin rot, the cause of its appearance can be dirty water, fin damage, stress, violation of feeding conditions. Most often, viviparous and labyrinth fish, neon and some voile species suffer from rotting fins.

Juveniles may die, and in adults there are more chances not only to recover, but also to grow new fins.

The causative agents of the disease are bacteria of the genus Vibrio, Pseudomonas, Aeromonas. In the initial stages, fin rot can be successfully cured, but the fins, which have been destroyed to the ground, cannot be recovered.

  • The fins begin to grow cloudy at the edges, a light-blue rim appears, which gradually expands – it is easier to notice signs in young fish with translucent fins;
  • Reddish spots and stripes – one of the symptoms of vascular occlusion in the fins, also starts from the edges;
  • Inflamed edges of the fins, they will split and shorten;
  • Whitish ulcers may form on the surface of the fins: if the disease is not treated, they transfer to the whole body;
  • In some species of fish, eyeballs begin to cloud;
  • Loss of scales.

The defeat of the fins is only external symptoms, in fact, a bacterial infection penetrates much deeper, affecting the muscles and internal organs, which is why it is very important to start treatment and isolate sick individuals in a timely manner.

It is possible to bring an infection to the aquarium, if you did not stand the quarantine and launched new residents into the reservoir, also the pathogenic bacteria are transmitted with live food or bad water. Rot can begin as a result of injury to the fins, so check that all the fish in your pond are compatible and that it is not overpopulated.

Treatment should begin with a water change (about 30%). Raise the temperature to a minimum of 25 degrees: if there are fish in your tank that cannot withstand such conditions, it is better to put sick individuals in an otsadnik.

The aquarium is cleaned of sludge, washed all the plants, pebbles, siphon ground.

If after a couple of days the disease continues to progress, you need to start medication.

  • Salt baths. They are not suitable only for soms. For 2 liters of water you need to dissolve 1 teaspoon of table salt and put the fish here for about 20-30 minutes. Baths do for 5 days;
  • Levomycetin. We buy tablets with the calculation of 1 piece per 20 liters of water, thoroughly grind, dissolve in a separate container (it will dissolve for a long time) and then pour it into the aquarium. After 3 days, you need to replace 30% of the total amount of water and add a new dose of medication;
  • Streptocid. Based on 1.5 grams per 10 liters. The scheme is the same as with chloramphenicol;
  • Bicillin-5. Mainly sold in ampoules (dissolve only 1/6 part per 10 liters of water). Pour water into a basin and place the diseased fish there for half an hour, repeat the course for 6 days;
  • Biseptol-480. 1/8 part of a pill for a 5-liter jar; previously, the pill needs to be pounded and dissolved in water. We settle the fish in this tank for a week, every day the solution should be new

Also for the treatment of fin rot, you can use other drugs, the most famous – Antipar, Biomitsin, Fiozept, Sulfonamid, Chloramphenicol, Malachite Green, Antibac, chloramine solution, hydrogen peroxide 3% and others.

  • Follow the regimes of feeding fish;
  • Promptly replace the water and clean the aquarium;
  • Keep fish with compatible species to avoid fin injuries;
  • Do not overcrowd the aquarium;
  • Maintain quarantine when replanting new fish;
  • Monitor the health of the inhabitants of the reservoir.

Fin rot is well treatable, the main thing is to start it in a timely manner.
